In an electrical storm, an electric field builds up in the space between a cloud and the ground. Lightning occurs when the magni

tude of the electric field reaches a critical value EC, at which air is ionized.
Required:
a. Treat the cloud as a flat square with sides of length L. If it is at a height h above the ground, find the amount of energy released in the lightning strike.
b. Based on your answer from part a, which is more dangerous, a lightning strike from a high-altitude cloud or a low-altitude one

A golfer strikes a 0.059-kg golf ball with a force of 290 N. If the ball moves with a velocity of 69 m/s,
Ymorist [56]

Answer:

0.014s

Explanation:

Given parameters:

mass of golf ball  = 0.059kg

force applied  = 290N

velocity = 69m/s

initial velocity  = 0m/s

Unknown:

Time of contact  = ?

Solution;

We know that momentum is the quantity of motion of body possess;

  Momentum  = mass x velocity

  Momentum  = 0.059 x 69  = 4.1kgm/s

Also; impulse is the effect of the force acting on a body;

  impulse  = force x time  = momentum

  So;

            Force x time  = momentum

                  Time  = \frac{momentum}{force }    = \frac{4.1}{290}    = 0.014s

A push or a pull on an object is known as a(n)
balu736 [363]
Force is a push or a pull of an object that causes the object to speed up, slow down, or stay in one place. In other words, a force is what causes an object to move. Friction and gravity are two types of forces that influence how an object moves.

Hope I can help you!

An object has a mass of 5 kg a displacement of 5 m and time of 25 seconds what is the momentum
PSYCHO15rus [73]

Answer:

1 Ns

Explanation:

Velocity = Displacement / time taken

           v = 5/25 ⇒ v = 0.2 ms⁻¹

Momentum = mass × velocity

                   = 5 × 0.2 = 1 Ns
