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.
Answer: Information, communication and technology helps sustain people living together in a nation

Communication keeps the people informed and give them an understanding, information is that data of knowledge that is being communicated and technology is the means by which it's communicated.
Answer:
c. make the norms salient to participants.
Explanation:
Field experiment: In psychological research, the term "field experiment" is described as one of the different studies that utilize "experimental design" that happens in any natural setting. While conducting a field experiment, the experimenter tends to examine or analyze the degree to which the manipulation of a single independent variable causes a change or alteration in the given dependent variable related to the natural environment.
In the question above, the researchers suggest that the specific role of the given confederate in the mentioned study was to make the particular norms salient to participants as it is significantly described that participants will model the confederate's behavior i.e, they will get influenced.
