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: Yes
Explanation: if the US has the resources to help the US should.
A cultural system creates a unique world that is experienced as "reality" by its members. The people of a certain culture come to accept the "realities" which form its culture.
However, when groups of different cultures come together, their "realities" become confronted. Creating a clash of cultures. The outcome of this clash is decided by the material power of each of this groups. The group with the most material will emerge victoriously and end up influencing the other group with its cultural system. Therefore, individuals from the influenced culture will end up learning a new "reality" by force. On the other hand, individuals of the influencing culture tend to see the others as "objects of study".
Clashes of cultures have been occurring throughout time, affecting the cultural authenticity of groups. Due to the constant blend of cultures, it is nowadays, very difficult to consider that a certain cultural group is "truly authentic".
I'm pretty sure it is: " D) None of the above "
