The diagram below shows the path of a comet around the Sun. с
How does the comet's energy change as it moves from point B to point C?
(Assume that total mechanical energy is conserved.)
A. KE decreases, GPE decreases
B. KE increases, GPE increases
C. KE increases, GPE decreases
D. KE decreases, GPE increases

What is true for a substance that releases energy

The famous scientist galileo galilei did several experiments with sloping planes, which he rolled metal balls down so that he could study motion. by changing the slope, he could study how the speed at which the ball rolled was affected. what was the independent variable in galileo's experiment? a. the speed of the ball b. the slope of the plane c. whether the ball moved d. what the ball was made of

How does a sample of helium at 15 degree celsius compare to a sample of helium at 215 k? a) the helium at 15 degrees celsius has a higher average kinetic energy that the sample at 215 k. b) the helium at 15 degrees celsius has lower nuclear energy that the sample at 215 k. c) the helium at 15 degrees celsius has slower- moving atoms that the sample at 215 k. d) the helium at 15 degrees celsius has smaller atoms than the sample at 215 k.
