Answer:
25J
Explanation:
power = work done ÷ time taken.
and work done = force applied × distance covered.
according to the question, the athlete lifts the weight of 100N upto 5m therefore;
100N × 5m = 500N/m
then onwards,
the work done (500 N/m) should be divided by the time taken to calculate the power,
500 ÷ 20s = 25J
is your answer.
hope this helped. :)
It look like a storm is forming out into the ocean and building pressure and maybe become a hurricane.
I hope this helps :)!!!
Answer:
D is the answer I think (0 w 0 )
Explanation:
Answer:
Explanation:
Kinetic energy of ball in motion = 1/2 m v² . Potential energy = 0
Let the minimum distance between the balls be d on collision.
Electric potential energy at that time= k Q²/d , Here kinetic energy is converted into potential energy . So
1/2 m v² = kQ²/d
d =2 k Q² / mv²,= 18 x 10⁹ x Q²/ m v².
