Answer:
The first egg is thrown at a wall and breaks because it has no time to decelerate and it breaks.
While, when a second egg is thrown at wall with same velocity and collides with a bed sheet, it does not break because it get more time to decelerate or collide with the wall. It reduces the amount of force exerted on the egg and it does not break.
the scientific study of natural forces such as light, sound, heat, electricity, pressure, etc.
Answer: 2000 watts
Explanation:
Given that,
power = ?
Weight of object = 200-N
height = 4 m
Time = 4 s
Power is the rate of work done per unit time i.e Power is simply obtained by dividing work by time. Its unit is watts.
i.e Power = work / time
(since work = force x distance, and weight is the force acting on the object due to gravity)
Then, Power = (weight x distance) / time
Power = (200N x 4m) / 4s
Power = 8000Nm / 4s
Power = 2000 watts
Thus, 2000 watts of power is needed to lift the object.
