Answer:
Change in momentum will be -4.4 kgm/sec
So option (A) is correct option
Explanation:
Mass of the ball is given m = 0.10 kg
Initial velocity of ball 
And velocity after rebound 
We have to find the change in momentum
So change in momentum is equal to
( here negative sign shows only direction )
So option (A) will be correct answer

Answer:
720 V
Explanation:
Given that,
The number of turns in primary coil, N₁ = 60
The number of turns in secondary coil, N₂ = 360
The input rms voltage, V₁ = 120 V
We need to find the output rms voltage of the secondary coil
. The relation between number of turns in primary coil - secondary coil to the input rms voltage to the output rms voltage is given by :

<h3>So, the output rms voltage of the secondary coil is 720 V. Hence, the correct option is (b).</h3>
