Shale/Coal/Oil are the most important mineral resources in Appalachia and are used as a source of energy by many in the world.
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:
Sand Stones!
Explanation:
Sand Stones are the most common types of sedimentary rocks.
The guiding principle of composite risk management (CRM) is to integrate CRM into all phases of missions and operations. All phases of the missions and operations include planning, preparation, execution, and recovery. Risk must be assessed at all levels of the mission and operations.
