How many miles in 5568 kilometers?

Miles is the imperial unit of measuring distances. Kilometers or meters is the metric unit. 1 mile is 1.6093 km. So to convert km to miles, we divide by 1.6093. 1 feet = 0.0001893 miles.1 yard=0.9144 meters. The corresponding distance in miles is 3459.80


What are the equations for velocity of falling objects?

The acceleration of free fall on earth, near the surface of the earth is 9.8 m/s2. On the moon it is 1.6m/s2But as the object moves further and further away from the earth, or any massive body, the acceleration due to gravity decreases by the inverse square law. Thus rather than being a constant value, the acceleration infinitely approaches zero as the object infinitely approaches infinity.The equation for this acceleration (which is identical to the equation for gravitational field, except for acceleration it is looking at inertial mass, while field is gravitational mass, but for all purposes they are the same):a = GM / r2Where G is the gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2 and M is the massive body creating the gravitational fieldand r is the distance from the center of the object to the center of the massive bodyAnd with this information, you can solve anything! The work done to move a body through space, the velocity to launch a satellite. Its amazing how physics actually work!


What are some ways you can conserve energy?

You can save energy in many ways, including unplugging your electric devices when you are not at home or switching off lights. Another good one in the winter includes wearing a sweater instead of turning up the heat. Those are just some examples.1) Install a programmable thermostat. It's surprisingly easy to install one yourself.2) Don't set the thermostat higher than you actually want it.3) Don't let furniture and draperies block the air flow from air registers.4) If your home has a boiler system, avoid covering radiators with screens or blocking them with furniture.5) Use rags or hand towels instead of paper towels or napkins.6) When using the fireplace, turn down the furnace to 55 degrees. If you don't, all the warm air from the furnace will go right up the chimney, wasting energy and money.7) Save on energy costs by comparing electricity rates from different power providers in your state.8) Keep plantings at least one foot away from your central air conditioning unit for adequate airflow.9) During late afternoon and early evening, turn off unnecessary lights and wait to use heat-producing appliances.10) Shade south- and west- facing windows during the hottest part of the day in the summer.11) Plant a tree. One well-placed shade tree can reduce your cooling costs by 25 percent.12) When planting trees, place leafy shade trees to the south and west, and evergreens to the north.13) As if it wasn't already obvious, use CFL light bulbs in your home. Get them for under a buck if you buy in bulk.14) A ceiling fan should blow air down in the winter and up in the summer.15) Set the fan on your central air conditioner to "on" rather than "auto." This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.16) Make sure your window air conditioner is the proper size.17) Vacuum registers and vents regularly.18) Raise the thermostat to about 78 to 80 degrees whenever you go to bed or leave the house.19) If your home can't accommodate central air conditioning, try a whole house attic fan.20) During the winter, remove window air conditioners and seal the windows with caulk and weatherstripping.21) Use safety plugs in all unused outlets. These are prime places for outside air to leak into your home.22) Hire an environmental consultant to assess your residence for hazards.23) If your home has a large, single-pane picture window, use heavy draperies during the winter to help hold back cold air.24) Reflective window film can help reduce heat gain during the summer, and it will keep furniture and carpets from fading.25) Check window panes to see if they need new glazing. If the glass is loose, replace the putty holding the pane in place.26) If drafts sneak in under exterior doors, replace the threshold.27) If you cannot install a weatherstripping threshold in a door, block the drafts with a rolled-up towel or blanket.28) Add fireproof caulk where the chimney meets the wall, inside and outside.29) When the fireplace is not in use, make sure fireplace dampers are sealed tight, and keep the glass doors closed.30) If you never use your fireplace, plug the chimney with fiberglass insulation and seal the doors with silicone caulk.31) Maintain your central air conditioner by cleaning the outside compressor with a garden hose (be sure to shut off power at the fuse or breaker first).32) Seal the edges of unused doors and windows with rope caulk.33) Don't forget to weatherize the attic access. Secure batt insulation to the back of the hatch or door, and use weatherstripping to seal the opening.34) Set the water heater temperature at 120 degrees - about halfway between low and medium.35) Cover the central air compressor with a tarp to keep it clean during the winter.36) Seal doors and windows with caulk and weatherstripping in the summer and the winter. A $15 weatherstripping kit can deliver similar effects to buying brand new windows..37) Add foam gaskets behind all outlet covers and switch plates.38) Unplug all electrical devices when not in use to reduce phantom load.39) Fix leaky faucets, especially if it's a hot water faucet. One drop per second can add up to 165 gallons a month - that's more than one person uses in two weeks.40) Use aerators on kitchen and bathroom sink faucets.41) Take showers, not baths.41) Purchase a residential wind power generator. You can find local providers here: wind power companies42) If your water heater is more than 15 years old, install an insulating wrap to reduce "standby" heat loss.43) If accessible, insulate hot water pipes passing through unconditioned space.44) Use smaller kitchen appliances whenever possible.45) Vacuum the refrigerator coils about twice a year to keep the compressor running efficiently.46) Don't leave the refrigerator door open.47) Don't leave the oven door open either.48) Keep the refrigerator temperature about 36-38 degrees, and the freezer at 0-5 degrees.49) Don't overload the refrigerator or freezer.50) Make sure the refrigerator is level, so the door automatically swings shut instead of open.51) Check the seal on your refrigerator door by closing it on a dollar bill. If you can pull the bill out easily, it's time to replace the gaskets52) Use your oven's self-cleaning feature immediately after cooking, while the oven is still hot.53) Use lids on pots and pans to reduce cooking times.54) Don't put a small pan on a large burner.55) Use energy saving power strips on your heaviest energy draining devices.56) Run the dishwasher only with full loads, and use the air-dry cycle.57) Wash only full loads of clothes, and be sure to set the water level appropriately.58) Use hot water only for very dirty loads, and always use cold water for the rinse cycle.59) Clean the lint screen on the dryer every time you use the machine.60) Remove clothes from the dryer while they're still damp and hang them up.61) Dry one load of clothes immediately after another.62) Switch to compact fluorescent light bulbs.63) Use light dimmers. Be careful with CFC bulbs because they may not be compatible with dimmer switches.64) Use motion sensors in your switches to have lights turn off when no one is in the room.65) Install timers on lights that tend to be left on for longer than they are needed.66) Keep lamps away from thermostats.67) Dust light fixtures regularly.68) Use only a single bulb in a multi-socket fixture.69) Replace an incandescent outdoor light or high-intensity floodlight with a high-pressure sodium fixture.70) Get a thermal link detectorto identifyhidden sources of cold or hot air entering your home. A side benefit is that they're really cool and you can use them telling how hot your pans are when you cook!71) Decorate with pale colors on walls, ceilings and floors. You will use less light.72) Get rid of spare refrigerators or freezers.73) Keep outdoor hot tubs covered when not in use.74) Keep waterbeds covered with quilts or blankets to help retain their heat.75) Install timers on appliances that tend to be left on longer than they are needed.76) Keep the garage door closed, especially during the winter.77) If you need a new lawn mower, consider an electric model.78) Instead of air-polluting and expensive charcoal or propane, try an electric or natural gas grill79) Install a low flow showerhead; don't worry they're well engineered today to still deliver high water pressure.80) Place humidifiers and dehumidifiers away from walls and bulky furniture81) If your home has no sidewall insulation, place heavy furniture like bookshelves, armoires and sofas along exterior walls, and use decorative quilts as wall hangings.82) When you take a vacation, turn off and unplug everything you can.83) When you're away from the house for an extended time, set your water heating to the lowest setting.84) Remember that it pays to invest in energy efficiency.85) Add a reflecting panel behind radiators86) If your home has electric baseboard heating, be sure to keep furniture and draperies away from the heaters, and leave at least a three-inch clearance under the heating unit.87) Keep curtains and blinds closed at night to keep cold air out, but open them during the day to let the sun warm the room.88) Avoid using space heaters, including electric, kerosene or propane models. Not only are they expensive to operate, they're also very dangerous.89) If you have hardwood or tile floors, add area rugs to keep your feet warm.90) If you'll be going on vacation, lower the thermostat to 55 degrees. This will save energy while preventing water pipes from freezing.91) If you have a wood-burning fireplace, have the chimney cleaned and inspected regularly, and burn only fully dried hardwoods to produce the most heat output.92) Always read the Energy Guide label carefully, and make sure you're comparing "apples to apples".93) When purchasing a refrigerator, choose the capacity that's right for your family.94) When replacing your furnace, make sure you choose the capacity that's right for your home.95) When replacing your central air conditioning, choose the appropriate capacity for your home.96) In almost every case, a natural gas appliance is more economical to use than an electric model.97) Replace your inefficient furnace with a geothermal heat pump. You can find geothermal heating companies online.98) Shop during the off-season. Many heating and cooling manufacturers offer significant rebates during seasonal sales promotions, and dealers may charge less for installation.99) Investigate new technology carefully. Some innovations, like convection ovens or argon-filled windows, may save energy and make life more convenient.100) Look for the "Energy Star" logo when you make a purchase.101) Don't over-dry your laundry.102) Don't bother pre-rinsing dishes with the idea that your dishwasher will work less hard.103) Start websites about saving energy to convince other people to do the same. That way your efforts can be multiplied.104) You can operate a couple of fans with a fraction of the electricity needed for air conditioning, and their cooling effect may make it possible to cut back on AC use.105) Heating food in the microwave uses only 20 percent of the energy required by a full-sized oven.106) Drive steadily--and a bit slower. Hard acceleration and abrupt braking will use more fuel than if you start and slow more moderately.107) If you travel at 65 mph instead of 55, you are penalized by lowering your mileage 12.5 percent. If you get your vehicle up to 75 mph, you're losing 25 percent compared with mileage at 55 mph.108) A loaded roof rack can decrease an SUV's fuel efficiency by 5 percent, and that of a more aerodynamic car by 15 percent or more.109) Stick with regular. If your car's manufacturer specifies regular gas, don't buy premium with the thought of going faster or operating more efficiently.110) After starting the car in the morning, begin driving right away; don't let it sit and "warm up" for several minutes.111) Try do-it-yourself low-E windows. If your windows don't have a low-E coating, consider applying a self-adhesive film on the glass.112) Stop Junk Mail write to: Mail Preference Service, Direct Marketing Association, 11 West 42nd St., PO Box 3861, New York, NY 10163-3861.113) Use reusable containers for food storage instead of wrapping food in foil or plastic wrap.114) Be aware of your paint you use - Use latex paint instead of oil-based paint. Oil-based paint is highly toxic.115) Inflate your tires well. This preserves the life of the tires and saves gas, which ultimately saves money.116) Recharge Your Batteries117) Bring your own shopping bags to the grocery store.118) If your purchase is small don't take any bag119) Use small plastic bottles, filled with water or stones to displace the amount of water in toilets120) Use cloth diapers when you put a diaper on your child121) Recycle your printer's toner cartridges. Find recycling companies near you.122) Buy products that are recycled. By purchasing these products, you are helping to conserve natural resources, and to protect the environment.123) Carpool or walk to reduce carbon dioxide pollution in the air.124) Buy in bulk--this saves not only on packaging that you would eventually have to dispose of, but reduces tremendously the amount of industrial waste generated to make the packaging.125) Shop for durable, long-lasting products. For example, use a metal razor instead of disposables, or a metal roasting pan instead of a disposable one.126) Reuse whatever you can, including aluminum pie tins, glassware, plastic cutlery and aluminum foil.127) Buy products with recycled contents.128) Precycle-make an effort to buy products with recyclable packaging.129) Leave the grass clippings on the lawn.130) Start a backyard composting bin for yard clippings.131) Make recycling easy by putting recycle bins in the rooms where you use the products.132) Replace paper cups, plates and napkins with washable, reusable cups and plates and cloth napkins.133) Keep used paper in a stack and use the flip side for scrap work. - - Perfect all of your documents before you print them.

Use caulk or expanding foam to fill those leaks.211) Look under your exterior doors to see if air is escaping. If it is, install a threshold.212) In the winter, use rope caulk to seal the moving parts of the window. You can remove this once the cold season is over.213) Make sure the access to your attic is sealed. You can also put insulation on the back of your access door.214) Set your hot water heater to the lowest temperature that will still allow you to have warm water.215) Water saving showerheads and faucets save hot water. Well designed units will not reduce your water pressure.216) One drop a second of hot water coming from a leaky faucet can use more hot water than one person uses in two weeks. Fix the leak.217) Baths use much more water than a 10 minute shower.218) Install insulation around your hot water if the label does instruct you not to do so. Many older units are not adequately insulated.219) Drain the sediment from you water heater.220) To conserve energy and reduce internal heat gain turn off computers, monitors, printers and copiers during non-business hours.221) Ensure that the built-in power management system for your office equipment is active.222) Ensure your screen saver is compatible with the computer's power management features, and that the setup allows the system to go into power saver mode.223) Using a laptop computer instead of a desk-top system can save 80-90% in electrical cost.223) Educate and encourage coworkers to be energy-conscious and to offer ideas about how energy can be saved.224) Designate a "responsible party" in your home to be responsible for and to promote good energy practices for the organization and/or facility.225) Reduce or replace inefficient, outdated or excessive lighting within your building.226) When replacing old lighting equipment evaluate new technologies that may need fewer fixtures and/or fewer lamps within existing fixtures.227) Ensure that light levels will remain at adequate levels before changing out technologies and/or reducing number of lamps.228) Where practical, replace incandescent lamps with compact fluorescent lamps (CFLs). Ensure you install compatible dimming technology if CFLs are used along with a dimming system.229) Replace incandescent "EXIT" signs with LED signs. LEDs use about one-tenth the wattage and last 50 times longer than incandescent-lamp signs.230) Install lighting occupancy sensors that automatically turn lights on or off, depending on occupancy. You can learn a lot about saving power on the websites of many local power companies.231) Take advantage of natural daylight: turn off or dim electric lighting when adequate sunlight is available to illuminate interior space.232) Ensure outdoor lighting is off during daytime.233) In winter, set office thermostat offices between 65 and 68 during the day/business hours, and 60 to 65 degrees during unoccupied times.234) In summer, set thermostats between 78 and 80 degrees during the day/business hours, and above 80 degrees during unoccupied hours.235) Adjust thermostats higher when cooling and lower when heating an occupied building or unoccupied areas within a building, e.g., during weekends and non-working hours.236) During summer months, adjusting your thermostat setting up one degree typically can save 2-3% on cooling costs.237) Consider installing locking devices on thermostats to maintain desired temperature settings.238) Install programmable thermostats that automatically adjust temperature settings based on the time of day and day of the week. - If you have multiple HVAC units, set thermostats to return to the occupied temperature a half an hour apart.239) Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline.240) Consider buying a highly fuel-efficient vehicle. A fuel-efficient vehicle, a hybrid vehicle, or an alternative fuel vehicle could save you a lot at the gas pump and help the environment. Electric cars are also becoming available. With the innovation of Elon Musk Tesla Motors, and many additional followers, are starting to produce more electric vehicles that get great mileage and don't produce emissions.241) Combine errands into one trip. Several short trips, each one taken from a cold start, can use twice as much fuel as one trip covering the same distance when the engine is warm.242) Replace clogged air filters to improve gas mileage by as much as 10% and protect your engine.243) Get regular engine tune-ups and car maintenance checks to avoid fuel economy problems due to worn spark plugs, dragging brakes, low transmission fluid, or transmission problems.244) Keep tires properly inflated and aligned to improve your gasoline mileage by around 3.3%.245) Use the grade of motor oil recommended by your car's manufacturer. Using a different motor oil can lower your gasoline mileage by 1%-2%.246) Check into telecommuting, carpooling and public transit to cut mileage and car maintenance costs.247) Reduce drag by placing items inside the car or trunk rather than on roof racks.248) Clear out your car; extra weight decreases gas mileage.249) Use air conditioning only when necessary.250) Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.251) When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces wear.252) Avoid high speeds. Above 60 mph, gas mileage drops rapidly253) Idling gets you 0 miles per gallon. The best way to warm up a vehicle is to drive it. No more than 30 seconds of idling on winter days is needed.254) Leaving the refrigerator door open really does waste energy.255) Your refrigerator should be set around 38 degrees.256) Make sure there is a firm seal on your refrigerator. If it releases even just a small amount of cold air, the energy costs will be significant.257) If you are going to use your oven's self cleaning feature, use it after cooking while the oven still has heat.258) Always use lids on your pots while cooking.259) Match your cooking pan to the size of the burner; don't cook on a large burner with a small pan.260) Purchase new grease plates under range burners because they will reflect heat more efficiently.261) Don't run your dishwasher until there is a full load. When you do, make sure to use the air dry cycle.262) Don't wash loads of laundry until you have a full load to put together.263) Use cold water for all but your most dirty loads of laundry. Always use cold water for the rinse cycle.264) Make sure to clean the lint screen every time you use the dryer.265) Dry one load of clothes immediately after another to take advantage of the heat built up in the machine.266) Switch to compact fluorescent light bulbs today!267) Use motion sensors in your switches to have lights turn off when no one is in the room.268) Install timers on lights that tend to be left on for longer than they are needed.269) Install timers on appliances that tend to be left on longer than they are needed.270) Keep lamps away from thermostats.271) Dust light fixtures regularly.272) Use only a single bulb in a multi-socket fixture.273) Replace an incandescent outdoor light or high-intensity floodlight with a high-pressure sodium fixture.274) Use low-voltage lighting kits to light walkways, patios and decks.275) Decorate with pale colors on walls, ceilings and floors. You will use less light.276) Get rid of spare refrigerators or freezers.277) Keep outdoor hot tubs covered when not in use.278) Keep waterbeds covered with quilts or blankets to help retain their heat.279) Keep the garage door closed, especially during the winter.280) If you need a new lawn mower consider an electric model.281) Instead of air-polluting and expensive charcoal or propane, try an electric or natural gas grill282) Unplug any electrical device that's not being used.283) Place humidifiers and dehumidifiers away from walls and bulky furniture284) If your home has no sidewall insulation, place heavy furniture like bookshelves, armoires and sofas along exterior walls, and use decorative quilts as wall hangings.285) When you take a vacation turn off and unplug everything you can.286) When you're away from the house for an extended time set your water heating to the lowest setting.287) Remember that it pays to invest in energy efficiency. One way to do so would be by contacting local solar companies to have photovoltaic panels installed on your residence.288) Always read the Energy Guide label carefully, and make sure you're comparing "apples to apples".289) When purchasing a refrigerator choose the capacity that's right for your family.290) When replacing your furnace make sure you choose the capacity that's right for your home.291) When replacing your central air conditioning choose the appropriate capacity for your home.292) In almost every case, a natural gas appliance is more economical to use than an electric model.293) Replace inefficient appliances - even if they're still working294) Shop during the off-season.
