The Difference Between

Because velocity has a direction but speed does not. A vector has both a numerical value and a direction but a speed has only a numerical value and therefore it can't be represented by a vector.

Diffraction is the bending of waves around an obstacle, while interference is the meeting of two waves. For instance, diffraction is what results from a pinhole blocking a wave source, the wave spreads out from that one point. This effect is what creates shadows, regions where the light source is blocked but it is not completely dark. Interference, however, results from two waves colliding with one another undergoing constructive and destructive interference, as in two chords being played. I think the confusion concerning these two different phenomena is the fact that two pinholes, two diffraction sources, results in interference of two sources, which is what the diffraction grating is, which creates the characteristic bands of light and dark interference patterns.

yes the heads will bolt right on but if you are putting a 305 in there the flywheel is different in the sense that the 327 has a small hole where the flywheel meets the crank (you need the starter for the 305)

Mediums are individuals who claim to have the ability to communicate with spirits or beings from the afterlife. They often use different methods such as clairvoyance, clairaudience, or channeling to relay messages from the spirit world to living individuals. Mediums are often sought out for spiritual guidance, closure, or reassurance from departed loved ones.

Think about it for a moment. Which is better stronger liquid chlorine or weaker chlorine. And most likely the weaker chlor. has been sitting in the sun on a dock for hours and is now at about 8% in strength. Hmmm.

The nuclear force is what binds the nucleons, which are protons and neutrons, together in the nucleus of an atom.

The binding energy is the amount of energy needed to break the atom apart.

The one is a force, and the other is a measurement.

One method to remove baked-on plastic from metal is to use a heat gun or hairdryer to soften the plastic, then scrape it off with a plastic scraper or butter knife. Another option is to soak the metal object in hot, soapy water to loosen the plastic before scrubbing it off with a non-abrasive sponge. Additionally, you can try using a mixture of baking soda and water to create a paste to help scrub off the baked-on plastic.

== == White gold is "labeled" by the karat weight on the inner rim of the ring....ex: 10K, 14K, etc... Also, real gold will leave a black mark on your face if wearing base makeup...so I have always been told and found to be true as I only wear white gold or silver...I personally do not like yellow gold.

Adding to prior response; Marks on a piece generally don't mean much unless purchased from a reputable jeweler.

Buy a nitric acid testing kid and follow the instructions.

Also try using a magnet on the piece, if it's attracted to a magnet- don't bother buying the rest kit, it's not real.

Another way to tell between silver and gold- Silver is slightly more gray, gold has a brighter shine to it, silver will tarnish fairly quickly (5-20 years)- gold takes 100+ years to tarnish.

No relation The short answer is none, a ton is a measure of mass and a kilocalorie is a measure of energy and they are different things. BUT weight is the force applied to a given mass by gravity, and energy and mass are interchangeable by Einstein's famous equation E=mc^2 or energy equals mass times the speed of light squared. Thus a relationship can be shown. Let's start by converting everything to metric units which are easier to deal with mathematically. A ton is 2000 pounds. A kilogram weighs 2.2 pounds. Thus the mass, in metric units, of one ton is 2000/2.2=909.1 kilograms. The kilocalorie (1000 calories) is equal to 4186 joules of energy. The basic units of energy are mass times speed squared. The joule, being a metric unit, is equal to 1 kilogram times one meter squared per second squared or 1Kgm^2/s^2. The speed of light, in metric units, is 2.998x10^8 m/s. So, if we took one ton's worth of mass and converted it into energy (the sun does this several thousand times a second) what would we get? 909.1 Kg x (2.998m/s)^2 = 8.171x10^19 Kgm^2/s^2 or joules. Dividing that by 4186 to convert from joules to kilocalories gives us 1.952x10^16 kilocalories. So, one ton is equivalent to 19,520,000,000,000,000 kilocalories. That's nineteen quadrillion, five hundred twenty trillion. If we do the calculation the other way and convert one kilocalorie into mass then we get 4186 J/(2.998 x 10^8 m/s)^2 = 4.657x10^-14 kg. Dividing that by 909.1 to convert it into tons gives 5.123 x 10^-17 tons or 0.00000000000000005123 tons. By the way, the word calorie is used in two different ways by scientists. The standard calorie that is used by physicists and chemists is only equal to 4.186 joules. Biologists and nutritionists use the Large Calorie which is equal to one thousand standard calories or one kilocalorie (4186 joules). So, when you say, "That cheeseburger has 800 calories in it," you really mean 800 kilocalories. Unless the question poster meant one ton [explosive] One ton [explosive] is equivalent to one million kilocalories [thermochemical].

Okay, first off- if your piece is marked for gold content- ignore that. I can mark a BMW 14k after a quick gold paint job.

First test- Use a magnet to see if the piece is magnetic, if it isn't- your next step is to buy a nitric acid test kit; They run about $20-$30 on E-bay. Rub the metal onto the stone firmly, drip some nitric acid on the rubbing on the stone- if the rubbing stays strong, your piece is gold. If it turns orange your piece is likely a lower karat.

If the rubbing; Disappears or turns green- your piece is fake.

The weight of a silver coin is typically higher than a copper-nickel coin of the same denomination due to the higher density of silver compared to copper and nickel alloy. For example, a US silver dime weighs 2.5 grams, while a US copper-nickel dime weighs 2.27 grams.

First, the term "test tube" is popular, but it is not the terminology used by scientists. They instead use the latin term 'in vitro' (literal definition: in glass; but modern definition more like 'outside the organism'; the opposite is 'in vivo'),

In vitro fertilization is simply putting sperm and egg together outside the body (and it's generally done in a dish, not a test tube!).

Cloning comes in two different forms: Reproductive Cloning and therapeutic cloning.

Reproductive cloning is the making of copy of an organism. It can be done in different ways. A natural form of cloning is to simply split an early embryo into two. At very early stages - say when the embryo is only a couple dozen cells, splitting it in half will result in the development of two genetically identical individuals. When this happens in nature, we call the offspring 'identical twins'.

Reproductive cloning can also be done by injecting the DNA from one organism into an embyronic stem cell of another, and then letting that cell divide and develop into an embryo and eventually an organism.

Therapeutic cloning is a completely different thing - When scientists talk about cloning - they are almost always talking about therapeutic cloning. Therapeutic cloning is the making of a copy of a single gene, or at it's most advanced, the copying of an entire strand of DNA. This is not used to produce another organism, but rather, to make copies of genes that can be altered and then engineered back into an animals genome.

For example, there might be a gene that confers a certain disease resistance, then can be cloned, and then spliced into the genome of a crop plant so that the plant is now disease-resistant.

Test tube cloning is altering the embryo. Test tube fertilization is when they take a sperm and egg and join them outside of the body. Then after fertilization it is placed back into the mother.

The muzzle velocity of a .270 caliber rifle can vary depending on the specific ammunition being used. On average, a .270 Winchester round can have a muzzle velocity of around 3,000-3,200 feet per second. It's always best to check the specific manufacturer's data for the most accurate information.

depends on what year it is, if it's been built for performance, kind of heads....lots of different compressions. usually for an early built engine somewhere in the ballpark of 8.5/1 up to 10.5/1. good luck with that!

No, not significantly. The fact that you use a solar cover at all is much more significant then what color it is. For all of the physicists out there, there ARE differences between the colors, but there are other factors like air temperature, ground temperature, and amount of sun that your pool receives, that will have a much greater effect on the water temperature than the color of the solar blanket. Thus, many people make their color choice based on other factors: - appearance (some people don't like the look of a black pool cover) - cost (some retailers charge different prices) - availability (some retailers only stock certain colors). Overall, I would say that Blue is probably the most common. Hope this helps ... Thanks for the input Tom. I purchased a 12 mil Blue/Silver solar blanket about a month ago. I agree, color doesn't make a great big difference and I like the appearance of the Blue. So far I see a pretty significant retention in heat and I also use quite a bit less liquid chlorine when the cover is in use.

The pressure in the tank will vary from your cutin pressure to your cutout pressure. If you increased the pressure in the system, your air-charge will now be wrong. A good rule of thumb is cutin - 2 psi.

ONLY if you can run a single wire along side the 2-wires. If not, running a 3rd by itself will cause the magnetic field of the wire to overheat (when they're run together, the magnetic fields cancel each other out).

Short answer: Probably not.

You cannot run a separte wire all by itself if the 8-2 is in a cable assembly. It isn't allowed by code. Technically you could run 8-2 cable, and then a separate #8 within a conduit, overheating will not occur and the wires do not cancell each other out when considering magnetic fields. It is however true that Phase A and Phase B have completely opposite magnetic fields, but overheating still occurs, this is why wires are derated when they are all run in the same conduit.

No, it is not safe to use a power strip to connect multiple pieces of equipment that each require a dedicated 20A outlet. This can overload the circuit and pose a fire hazard. It is recommended to consult with an electrician to install the appropriate outlets for your equipment.

Eat more protein, eat less fat. This is the general formula to complete your task. Also, eat carbs (fruits, vegetables, pasta-- all without butter or oil) for quick energy. Exercise: Aerobics will cause you to look thinner, free weights and weight machines will build bulk. The middle ground will make you lean and hard: pushups, situps, chinups. You can also try Isometrics, which will build up mass without making you lithe. Whatever you do, be careful when you first start exercising, and take it easy on yourself. The point is to be fit, not to kill yourself.

Liposuction. Seriously, this is controversial in the medical community. Many doctors claim you NEVER lose fat cells, the cells themselves only become smaller. Thus, if you develop a large number of fat cells in early childhood, you will probably struggle with weight all your life.

Hey Ray==I presume the fuse is blown is why you think there is a short. You have to examine the wiring to find where the wire is shorted out. If you have a trailer harness, start there. If the vehicle has been wrecked. look there as body men have a habit of pinching wires in the repair. If not, you just have to follow the wiring harness and find out where it is. Goodluck, Joe
