Answer:
An electric generator creates a time-dependent induced voltage.
An electric generator converts mechanical energy into electrical energy.
Explanation:
An electric generator works on the principle of electromagnetic induction. This phenomenon hinges on the fact that moving a conducting wire through a magnetic field produces electricity. Electricity is generated as long as there is relative motion between the conductor and the magnetic field. The emf generated is known as induced emf or induced voltage.
The electric generator converts mechanical energy to electrical energy.
Answer:
kE=1/2mv^2
Explanation:
here
KE= 15000j
velocity =20m/s
mass=?
now
mass=
15000×2= (m)20^2
30000=m ×400
30000÷400=m
Mass (m)= 75
therefore mass is 75kilogram
