The diagram shows a swinging pendulum. A pendulum hanging from a bar is shown in 3 positions. 1 is swung to the right, 1 to the left, and 1 in the middle. Solid lines connect the bob to he support in the right and left positions. A dotted line connects the bob to the support in the center position. Dotted lines connect right, left, and center along the arc of the pendulum swing.

Which best explains what happens to the motion of the pendulum due to the law of conservation of energy?

The mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving.
The mechanical energy disappears as the pendulum slows and eventually stops moving.
The pendulum will continue moving at the same speed until someone stops it because energy cannot be destroyed.
The pendulum will slow down but will never stop moving because energy cannot be destroyed.

B. The mechanical energy disappears as the pendulum slows and eventually stops moving.

Explanation:

the top will have the most kinetic and the bottom will have the most potential.

Don’t listen to the other person, B is incorrect. A is the correct answer.

Explanation: The law of conservation of energy states that energy cannot be created nor destroyed. B says that the mechanical energy disappears, but this is wrong. It changes into another energy, but the energy doesn’t disappear.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
