Answer:
Explanation:
A generator is a device which converts mechanical energy into electrical energy.
It is based on the principle of electromagnetic induction.
The armature coil of the generator rotates by using the mechanical energy. As the armature of the generator rotates, the magnetic flux linked with the coil changes. When the magnetic flux linked with the coil changes, an induced emf is developed.
the magnitude of the induced emf is equal to the rate of change of magnetic flux.
Explanation:
A) use the formula:
B) use the formula:
with angular velocity u calculated in A)
B. Fusion requires very high pressure and temperature.
Explanation:
Nuclear fusion is the combination of atomic nuclei into larger ones with the release of a large amount of energy.
Nuclear fission is the decay process in which a heavy nuclide is bombarded with with neutrons.
- Both processes release a huge amount of energy.
- But fusion produces far more energy.
- The reason why nuclear fusion is not in use is because of the high pressure and temperature needed start it.
- The activation energy is high and the energy barrier is very great.
- Only the core of the sun naturally favors fusion
