Answer: <u>Option A: </u>The gas and food are examples of energy.
Explanation:
Work and energy are inter-related. Energy is required to do the work. An equal amount of energy is converted into work. Work and energy have same units. The SI unit is Joule.
The gas and food are sources of energy. They act as fuel. This energy is utilized to perform work. The gas is used to run the car. The food is metabolized inside the body which is a source of energy and utilized to perform every day work.
Hence, The gas and food are examples of energy.
Answer:
<em>Answer A. Fission, steam, turbine, electricity, cool water</em>
Explanation:
<u>Nuclear Energy Production
</u>
Nuclear energy is produced by splitting uranium atoms in a process called fission. This generates heat and it's managed to produce steam, which later is used by a turbine generator to generate electricity. The heat must be taken out of the system, so a cooling process, usually involving water is the final step.
Because nuclear power plants don't burn fuel, they are known as clean energy sources.
Answer A. Fission, steam, turbine, electricity, cool water
No, Their arms and back legs are too short, but the mesosaurus was also a coastal animal! It's very unlikely.
-- Conserve. Don't use more than we need. There isn't any more of it.
-- Conserve. Don't pollute what we have. There isn't any more of it.
Of course, what we REALLY need to do is <u><em>convince</em></u> great numbers of people to go along with these suggestions. Otherwise it won't work.
Answer:
KE = 1/2 M V^2 = 1/2 * 25 * 10^2 = 1250 J
Check
M2 = 1/2 M1
V2 = V1 / 2
E2 = 1/2 * 1/4 E1 = E1 / 8 = 10000 / 8 = 1250 J
