Active Voice:- The fire damaged the buildings. Passive Voice:- The buildings were damaged by the fire
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.
Since not all the women have been asked (it's impossible, it would take too much time and be too expensive), we can only have an estimate - it's around 50%, or half the women.
The various statistics, depending on the county and a survey are between 40% and 60% - so that is the correct answer.
But as I said, depending on the sample and the source, that number can slightly vary.
