Energy was lost due to work done by the ball pushing on the floor during the collision.
Answer:
Option B
Explanation:
As per Newton's third law of motion, every action has an equal and opposite reaction. So if an object is made to drop from height to reach the floor, then its kinetic energy when the object is moving will be transferred to the floor on hitting the floor. Thus, this loss of kinetic energy will lead to rebounding of ball to 90% of original fixed height and not to the same height. So the point the ball hits the floor, the kinetic energy of the ball will be utilized to push on the the floor such that the ball can rebound itself. Hence, it is stated that the loss of kinetic energy of the ball during collision is because it is lost due to work done by the ball pushing on the floor during the collision.
The answer is B, to maintain law and order in a country
I believe the answer is: Sheet metal
Self tapping screws are made by creating a gap in the connector within the thread of a crew, which creates a flute and cutting edge just like what we see on tap. This makes self tapping screws able to tap their own hole in a sheet metal while normal screws can't.
