In the game of pool, a player uses a stick called a cue to strike a white ball so that it will hit another ball. Suppose
that a pool player strikes the white ball so that it rolls
toward a motionless black ball. When the two balls collide,
the white ball stops moving and the black ball starts
moving
Which two statements provide evidence of conservation of energy in this
example?
O A. The black ball moved because the white ball created more energy
during the collision
B. The black ball moved because the white ball transferred kinetic
energy to it during the collision.
O C. The white ball stopped because all its kinetic energy was
transferred to the black ball.
D. The white ball stopped because energy naturally disappears over
time

The answer to this question would be B(The black ball moved because the white ball transferred kinetic  energy to it during the collision.)

Explanation:

For example, energy can't be created or destroyed, so D is wrong because it is saying the energy is naturally destroyed, C is incorrect because it didn't mention the collision, A is incorrect because it is saying energy is created. Because the law of conservation of energy states that energy can't be created nor destroyed

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
