Answer:
Water in an artificial lake held behind a dam
Explanation:
Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.
Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.
sound travels through a medium in mechanical waves a mechanical wave is a disturbance that moves and transports energy from one place to another through a medium
Answer:
The velocity of the one thrown up will be the same as the second one
Explanation:
They will fall and hit the ground at the same time although they have the same velocity because object one although has double height it has initial velocity of zero
Answer:
25,300,000,000,000 miles away
Cardiac, smooth, and skeletal. cardiac muscle cells are located in the walls of the heart and appear striated and are under involuntary control. smooth muscle fibers are located in walls of hollow visceral organs except the heart they also appear striated. skeleton muscle is found between bones and uses tendons to connect to the epimysium to the periosteum, or the outer covering of bone. skeletal muscle is shaped and adapted in many ways.
