Explanation:
Using kinematics,
t = 4s
u = 0m/s
a = 9.8m/s^2
Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.

Answer:
The induced emf in the coil is
Explanation:
From the question we are told that
The magnitude of the emf for a single loop is
The number of turn of the new wire is N = 5
The magnitude of the emf induced in the coil is
substituting value
