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.
For a cardiac arrest in the emergency department, the priority treatment for ventricular fibrillation is immediate bystander CPR.
cpr is short for cardiopulmonaryes reuscitation. we perform it by Push hard, push fast. Place your hands, one on top of the other, in the middle of the chest. Use your body weight to help you administer compressions that are at least 2 inches deep and delivered at a rate of at least 100 compressions per minute.
Cardiopulmonary resuscitation is a first aid technique for individuals in cardiac arrest that involves rescue breathing and a defibrillator. The aim of this technique is to ensure the brain remains operational and keeps blood pumping around the body, until further medical help can arrive.
