Jason knows that the equation to calculate the period of a simple pendium T=2π√L/8, where T is the period, L is the length of th
e rod and g is the acceleration due to gravity. He who knows that the frequency (f) of the pendulum is the reciprocal of period. How can he express L in terms of g and f?

Answer:
The magnitude of the voltage is and the direction of the current is clockwise.
Explanation:
Given that,
Number of turns = 9
Magnetic field = 0.5 T
Diameter = 3 cm
Time t = 0.14 s
We need to calculate the flux
Using formula of flux
Put the value into the formula
We need to calculate the emf
Using formula of emf
Negative sign shows the direction of current.
Hence, The magnitude of the voltage is and the direction of the current is clockwise.
