Why is the sun considere d earth main energy source?
The sun is a major source of power.....because, it gives us warmth, and light-well duh! It also can be used with solar panels, just simply buy a solar panel, put it outside, and that solar panel will power your WHOLE house! Its better to put out solar panels if you live in another place. sorry its not very clear, but i hope it will do!
What branch of science involves the study of all forms of energy?
For thermal energy it is thermodynamics, for mechanical energy it would be mechanics or mechanical engineering, for electrical energy electrical engineering, and for nuclear energy, nuclear physics. There doesn't seem to be one branch of science for energy as a whole.
Is radiant energy a form of potential energy only?
Neither. It is an electromagnetic radiation, that is one that is part of a whole spectrum or range of radiation of the same basic type, that stretches from long wave radio waves to gamma rays, and includes visible light, microwaves, and x-rays. These all carry energy dependent on the power of the source. Humans react most to the infra red range which is what you feel on your skin in front of a radiant electric fire. Visible light is generally not so powerful and we absorb it in our eyes, but it can be made dangerous as in lasers. Microwave energy is used in cookers where it causes water molecules to vibrate and heat up. Xray and gamma Ray energy is dangerous when more than the safe level, because they cause ionization in the body material which can induce cancer. These are all forms of radiant energy.
What type of energy do people get from the food they eat?
we get chemical energy from food.but they are expressed in calories.two persons misread the questions i think.ok,see about the chemical energy. The energy held in the covalent bonds between atoms in a molecule is called chemical energy. Every bond has a certain amount of energy. To break the bond requires energy -- in chemical language it is called endothermic. These broken bonds then join together to create new molecules, and in the process release heat -- chemists call this exothermic. If the total heat given out is more than the heat taken in then the whole reaction is called exothermic, and the chemicals get hot. The burning of methane in oxygen is an example of this. If the heat taken in is more than the heat given out then the whole reaction is endothermic and the chemicals get cold. Combining carbon and hydrogen to make methane is an example. We rarely meet such reactions in every day life. They happen in living cells, the energy being supplied by sunlight or some other source. ATP is the molecule used by life to carry chemical energy. The bond between two of its phosphate groups carries a lot of energy because both phosphates have negative electric charge.
What are facts about autotrophs?
1. They can make their own food. 2. They usually obtain energy through the synthesis of substances, like plants get energy from photosynthesis. 3. They support the whole earth's ecological system. They are at the bottom of the food chain.
Which is easier to use as an energy source ATP or glucose?
The whole point of cellular respiration is to harness energy from the original source, glucose, and transform it into a usable and stable source, ATP.
How does energy move through hydroelectric energy?
energy moves through hydroelectric energy because of all the heating and the movement of the whole source
What distance does the Gower peninsula cover?
the gower peninsula covers the whole of south wales the gower peninsula covers the whole of south wales

Of what are carbohydrates a good source?
Carbohydrates are a good source of energy.
Can generators be connected to any source of mechanical energy that makes their parts spin?
That's the whole point of a generator - to convert mechanical energy into electrical energy, by making the generator's parts spin.
What is needed to start a fire?
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
What is the disadvantage of hydrolectric energy?
It blocks rivers, which is bad for migrating fish, is ugly to humans and is only a limited source of energy: it could never supply enough to power the whole world.
What is mitt Romney's position on pollution?
Considering that he is in favor of coal as an energy source, he doesn't seem to care about pollution or the environment a whole lot.
