War material. Steel, copper, oil, lead are needed to make war material.. Answer . Strictly speaking it's materiel . Materiel are "goods of war" like tanks, clothing, aeroplanes etc. These require raw materials for manufacture, naturally enough. Materiel refers to objects, material to matter.
To make photosynthesis occur, you need 3 raw materials : carbon dioxide, water, and sunlight. Carbon dioxide comes from air, water from xylem roots, and sunlight from sunlight! Below is a good picture which explains about photosynthesis. As you can see here in the picture, sunlight, carbon dioxid…e, and water enter the leaf through either sunlight, xylem roots, or air. I plant then uses this, and the end products are glucose (sugar) and oxygen. The oxygen is what we breathe in. When we eat a plant, we eat that glucose that is getting released. Breaking down stored carbohydrates or sugar from oxygen is called cellular respiration, which is the opposite of photosynthesis. HOPE THIS HELPS, DUDE! (MORE)

When you look at diagrams for wiring fluorescent lights you do not see clearly a neutral wire All electrical components need it Where is it in fluorescent lights?
Actually, many components do not have or need a neutral. 3-phase equipment such as motors, heaters and the like do not use a neutral. Some older 240V electric clothes dryers (in the US) did not have a neutral. The 2.5 ton, 240V airconditioner on my roof doesn't use a neutral either.. Fluorescent fi…xtures do however, as you note, need a neutral. The two power wires coming out of the ballast are usually a black and a white wire in the US, the white wire is the neutral.. On older fixtures with a separate starter, the white wire (neutral) may not go to the ballast. Instead it goes to the tube socket. It's still white, though.. Note that many of the current rapid-start fixtures also need a grounded reflector to reliably start. These fixtures will require a hot, neutral AND ground conductor, properly connected, to work.

dirt with vermiculite seeds water and sunshine and most of all a person who will make sure water is given to a plant. also you can buy a grow kit that includes the above and also furnishes a grow light incase you don't have a sunny enough room to begin the germination process. if room allows you can… try what i used to do; built a coold frame in your basement and fill frame with dirt about 2 inches from the top of the 2x6 boards then get a sheet of plastic put it over the diry in a tent style plant your seeds and about once a week let the dryer exhaust into the frame what this does is make a rain forest under the plastic with the grow light and humid air from the dryer . your seeds will germinate fast and by may 1st your tomatoes will be ready to plant outside with flowers on them and some green tomatoes. other plants you may be able to pick for the table, like peas and lettuce. try it if you can it's really fun and there's nothing more funny than sitting around with a few buddies drinking beer and watching the garden grow, wives don't think it's funny when you come home half drunk and explain to them what you were doing (MORE)
Answer for USA, Canada and countries running a 60 Hz power supply service. . No, check the inside of the fixture and look for a label that states "good for continuous row wiring." If you find this the fixture is approved to be used as a raceway providing that the fixtures are all bolted together …end to end. The wiring should be done with wire good for use in 90 o heat as there is a heat build-up from the ballasts. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. . Before you do any work yourself, on electrical circuits, equipment or appliances, always use a test meter to ensure the circuit is, in fact, de-energized . IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. (MORE)
Fluorescent material immediately glows when exposed to ultravioletradiation, that is it fluoresces. Phosphorescent material slowlyabsorbs and re-emits the radiation it absorbs. This enablesphosphorescent material to absorb visible light spectra to "glow inthe dark" at a later time.
comparing to the traditional light bulbs energy efficientfluorescent light bulbs uses 25% to 75% energy and saves money alsoand it lasts up to 3 to 25 times long so there is no need toreplace energy efficient fluorescent light bulbs often.
The first three are the requirements and the last two are the products. Carbon Dioxide + Water + Energy (Sun) = Glucose + Oxygen 6CO 2 + 6H 2 O + Energy (Sun) = C 6 H 12 O 6 + 6O 2
Sound travels in waves, these waves need a medium to travel through. Think about water in the ocean, without the water, there would be no waves. Same concept.

The electricity excites the florescent materials causing them to glow and give off light. Early light bulbs are incandescent or give off light with more heat than florescent bulbs which use much more electricity to make the metal filament glow with also much heat given off.
Need For Material Management: 1. To have adequate materials in hand when needed 2. To pay the lowest possible price, consistent with quality and value requirement for purchases materials. 3. To minimize the inventory investment. 4. To operate efficiently.

Agar with a nutrient suitable for the desired bacteria. If you need to count them, then a reagent is needed too, that one can see a difference on the agar plate where bacteria colonies have grown. To apply the sample, you need sterile equipment to dilute it to desired concentration and a spatula… to spread it on the plate. Then you need a sterile place to incubate the plates at the right temperature, e.g. 37 Â°C. For professional counting, one often can use a binocular microscope and a hand counter. (MORE)

If you mean the chemical element nickel, all you need is some nickel-containing ore and the means to refine it; as an element, nickel itself cannot be altered except through nuclear fusion. If you're referring to a coin containing nickel, such as the U.S. five-cent piece, you need an alloy that i…s 75% copper (and only 25% nickel!) and a coin press. (In fact, the Canadian version has even less nickel than that: a plating that amounts to 2% of the weight of the coin, over a core that's mostly steel with a bit of copper.) Be aware, of course, that attempting to make and use your own money is considered counterfeiting, and is illegal in almost all parts of the world. (MORE)

The answer is simply100 Watts. The Wattage rating of electric light bulbs is just the amount of electricity they consume. So a 60 Watt bulb would take 60 Watts of electricity. In fact, if you could buy a 100 Watt CFL, it would have the light output equivalent to about eight 100 Watt conventional (in…candescent) light bulbs. (MORE)

The ballast of a fluorescent lamp (whether modern electronic or conventional large inductance) will cause a kickback voltage when the lamp starts up that causes electrical breakdown and destruction of the standard dimmer's Triac (a solid state switch). There are some special electronic ballasts that… don't do this and will work with ordinary dimmers (just don't expect a linear dimming effect like you got with an incandescent bulb). The special dimmers that work with ordinary ballasts use special high voltage switching circuits with extra protection components to prevent this damage. This makes them more expensive. (MORE)

I never heard of alimimium but i do know that aluminium can be made from Bauxite ore. The process. Aluminium oxide has a melting point of about 2,000 Â°C (3,600 Â°F). Therefore, it must be extracted by electrolysis. In this process, the aluminium oxide is dissolved in molten cryolite with… calcium fluoride and then reduced to the pure metal. The operational temperature of the reduction cells is around 950 to 980 Â°C (1,740 to 1,800 Â°F). (MORE)
Light, carbon dioxide, and water are the materials needed to startphotosynthesis. The carbon dioxide is needed for the Calvin cyclewhile the light and water are required for the light reactions.
There are certain safety ethics and compliance solutions that an individual actually needs when dissecting a certain body or something else. It depends on what you are going to dissect, for example, a frog as well as give valid reason why you need to dissect it.
They are sort of related; however, glow in the dark materials are actually referred to as phosphorescent. The whole idea behind photoluminescence is that a material absorbs radiation (light) and then re-emits it. Phosphorescent materials absorb light, but release it at a much slower rate. Therefore,… they absorb light when they are exposed to it, and then continue releasing it after the light source is removed. Fluorescence, on the other hand, is a material that that absorbs ultraviolet radiation (such as light from a black light) and then releases visible light. (MORE)

First, and most important, you'll need knowledge. You'll need to understand how microcontrollers work and how to program them. You'll need to understand digital communications and if you want your robot to speak and/or understand, you'll need to understand speech synthesis. You'll need to understa…nd sensors, A to D converters, actuators, stepper motors, metal fatigue, torsion, sheer strength, "polar moment", and how to move your robotic pile of bolts, if, in fact, you decide that you want it to be mobile. Of course, if it's to move, you'll need to have a way to keep it from falling over, and that problem has been worked on for years, since bipedal locomotion has been a challenge for the robotics industry. You can add hardware to your knowledge, but first you have to have the knowledge, and once you have that knowledge, you will also understand that there are a lot more challenges that would benefit from your abilities.

To answer this question some values must be stated. The voltage and amperage must be known to find the wattage. W = A x V.
The voltage of your area is what determines the operating voltage of all equipment. Equipment from other countries usually has to use a transformer to get the correct voltage. The voltage on a fluorescent fixture is printed on the ballast of the fixture. See if the voltage on the ballast matches the… supply voltage of the system that you are going to use to operate the fixture. (MORE)
