You roll a bowling ball down the lane and it takes 23 seconds to reach the pins. what is the total time it takes the ball to move?
question 1 options:

a 0s

b 23s

c 46s

d none of the above

t = 23 seconds      

Explanation:

It is given that, you roll a bowling ball down the lane and it takes 23 seconds to reach the pins. The ball moves under the action of gravity. The value of acceleration due to gravity on the surface of Earth is

The total time taken by the ball to move is equal to the time taken by th bowling ball down the lane.

So, total time it takes the ball to move is 23 seconds.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
