As per Faraday's law of induction we know that induced EMF in a conducting closed loop is equal to rate of change in flux in that loop
So here we have
now when we move out a coil from magnetic field then in this case there will be EMF induced in that coil as here magnetic flux is changing with time linked with the coil.
Now this induced voltage will remain constant if coil is moved out uniformly
But it will not remain constant if coil is moved out with non uniform speed
So this statement is not always true
so answer must be
<u>FALSE</u>
Answer:
its speed is insignificant before the diver's speed change, so the result does not change
Explanation:
In this exercise of conservation of the momentum, the system is formed by the diver and the Earth
initial instant (before jumping)
p₀ = 0
final instant (after jumping)
= m v + M v²
how momentum is conserved
p₀ = p_{f}
0 = m v + M v²
v² = m / M v
since the mass of the Earth is M = 10²⁴ kg
its speed is insignificant before the diver's speed change, so the result does not change
