I NEED THIS ASAP. Please :) Please post the answers as soon as you are done one question. Thank you so much! :)

During a physics lab on Conservation of Energy, a student pulls the pendulum back and releases it to set it in motion. Then they observe the pendulum swinging back and forth. A) Describe the energy transfers that occur as the pendulum swings back and forth. B) After a while, the student notices that the pendulum's swing is getting smaller and smaller, and it eventually stops its motion. Explain why this is not a violation of the law of conservation of energy.
