What is the ultimate source of the energy that drives a tornado?
As with all weather on Earth, the ultimate source of energy is the sun. The sun heats the Earth, which create masses of warm, moist air that act as fuel for thunderstorms. Under the right conditions, these storms can sometimes produce tornadoes.
What is the source of energy for waves?
The question asks for the source and may mean the energy source that generates the waves. Alternatively, the question may be asking how waves can be a source of energy. In the first case, energy goes into the wave and in the second case energy comes out of the wave. Briefly, waves are the regular repetition of an action, which may be vertical rise and fall of water as in water waves or compression and rarefaction of air as in sound waves or regular variations in electromagnetic fields as in light or radio waves. In all these cases, waves also move which is another characteristic. (To get technical, there are also standing waves but such waves may be taken to be two counter moving waves.) Physical waves are generated when the medium in which they exist is caused to move by some source of energy. A vibrating drum head makes a sound wave. The wind makes water waves. In the case of electromagnetic waves, the source of the fields, i.e. charges and currents, move in a regular way to generate the waves. The "source" of energy is the the energy that goes into moving the medium, e.g. the wind or mechanical motion of the drum membrane or the causative forces that move charges and currents in electromagnetic waves. In these cases, energy comes from the "source" to create the wave. To have a wave act as an energy "source", or to get energy out of a wave, you have to have the waving or oscillating material exerting a force on something else. Clearly, water waves may exert a buoyant force on a floating object, for instance, and that floating object as it moves up and down may exert a force and thereby do work and so act as an energy source. The same applies to sound, but the pressure waves are typically going to create movement over very small, perhaps micron scales, so mechanical work is less obvious. Perhaps more obvious would be sound causing an object to vibrate and that vibration being converted into heat energy. In the case of electromagnetic waves, the microwave oven actually heats objects by having the electromagnetic waves act on charges in atoms and molecules which then physically move and vibrate and that motion is heat. In summary, there are many kinds of waves and to create a wave there must be an energy source. The waves then contain that energy and the energy can be extracted from the wave thereby diminishing the wave.
How did the National Energy Act help ease America's energy crisis?
Out of the battle came the National Energy Act. The act placed a tax on gas-guzzling cars, removed price controls on oil and natural gas produced in the United States, and extended tax credits for the development of alternative energy. With the help of the act, as well as voluntary conservation measures, U.S. dependence on foreign oil had eased slightly by 1979.
Which sources of energy come indirectly from the sun?
Fossil fuel energy: originated in plant and animal life which depended on the sun as a source of energy.Wind energy: comes from the sun heating the air both directly and indirectly by heating the land and water surfaces of the earth which then transfer energy to the air.Wave energy: comes from the wind acting on the surface of the ocean and the wind got its energy from the sun.Biomass energy: comes from plants which get their energy from the sun via photosynthesis.Nuclear energy: doesn't come indirectly from the sun, but it does come from dying stars since the heavy element uranium was produced in novas and supernovas.Geothermal energy: comes partially from radioactive decay of the heavy elements uranium and thorium which originated in novas and supernovas, but the rest comes from gravity during the original formation of the earth.
How does a hair dryer act as an energy converter?
it is an energy converter because you are using electrical energy and converting it to heat energy when drying your hair
What law was passed by congress to prevent financial panic?
The Federal Reserve Act...Apex:)
What was the singular achievement of the Federal Reserve Act?
Establishing the Federal Reserve was the singular achievement of the Federal Reserve Act.
What law was passed by congress to prevent financcial panics?
The Federal Reserve Act...Apex:)
Why is emulsification of fats is necessary?
Emulsification of fats is necessary because a fat globule has large surface area for enzymes to act upon it. Emulsification reduces the surface area and then more enzymes can act upon it and thus can produce more energy.
Who signed the Federal Reserve Act?
President Woodrow Wilson signed the Federal Reserve Act into law in 1913.
What is the difference in the way saturated and unsaturated fats act in the body?
The difference between saturated and unsaturated fats lies in the bond, because the shapes determine how the various fats act in the body.
How many federal reserve districts did the Federal Reserve Act divide the US into?
There are twelve Federal Reserve districts in the U.S.
What is one of the functions of fat?
Fats have several functions in the body: They are primarily a store of energy. The body stores excess starches as fat, which contains twice the amount of energy as the same mass of carbohydrates or protein. Fat oxidation provides the body tissues with warmth. Fat layers provide insulation in the skin and cushioning of the major internal organs (especially in the abdomen where there are no protective bones).
Is the breakdown of glucose endothermic or exothermic?
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
What did the federal reserve act signed by president Woodrow Wilson in 1913 establish?
The Federal Reserve.
What do the 4 organic compounds do for the body?
The 4 main organic compounds: Carbohydrates = create energy Lidids = act as an energy reserve nucleic acids = compose RNA and DNA proteins = do most of the work in a cell
Fats oils and waxes are all classified as what?
Fats, waxes and oils are all also known as lipids.
