nutrient that we consume have chemical energy stored within their chemical bond. This nutrient molecules are our main source of energy for metabolism.
chemical energy is potential of chemical substances to undergo transformation through a chemical reaction to transform other chemical substance. food energy is released during digestion whereby molecules in our food are broken into smaller pieces.As bond between these atom loses a chemical reaction occurs.
Answer:
- Mars-sized planetesimal collides with Earth
- The molten material is ejected from Earth
- Material accretes to form the Moon
- The moon begins rotating and revolving around Earth
Explanation:
This is how it is believed that the moon was formed. During the formation of the solar system, rocks, ice, and gases came together in a collision, due to their own gravity, forming the rock and gas planets that we see today. During this bombardment, some material became ejected the earth to form the moon. The moon revolves around the earth because it is within the pull of the earths gravitational field.
Answer: Option D.
Newton's cradle has the most potential energy when the balls are at rest.
Explanation:
Newton's cradle demonstrate principle of conservation of momentum which states that when two objects collide, the total momentum before it's collision is the same as it's momentum after it collision.
Newton's cradle has the most potential energy when the balls are at rest because an object at rest or by virtue of it's position has potential energy when it's not moving or stationary. A stationary or objects at rest posses potential energy.
Potential energy is the energy posses by a body or object that is not moving or at rest or energy stored by an object by virtue of it's position.
