Answer:
The number of turns in the secondary coil is 48.
(B) is correct option.
Explanation:
Given that,
Number of turns on primary coil= 1000
Primary voltage = 2500 V
Secondary voltage = 120 v
We need to calculate the turns in the secondary coil
Using relation between voltage and number of turns in primary and secondary coil

Put the value into the formula



Hence, The number of turns in the secondary coil is 48.
Centripetal Force (Fcp) = ?
His arm length = Radius (R) = 0.75 m
Discus velocity = Linear Velocity (V) = 5 m/s
Discus mass (m) = 2 kg
Centripetal Acceleration (Acp) = V^2/R or W^2 x R
In this case i will use the V^2/R formula, because it uses the discus velocity (V).
