The most significant change in the comet's energy as it moves from point D to point A KE increases, GPE decreases.Option C is correct.
<h3>What are comets?</h3>
Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice.
They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a plane.
As the comet transitions from point D to point A, the biggest energy shift is seen. GPE declines as KE rises. The right answer is C.
Hence option C is correct.

Answer:

Explanation:
The period of a physical pendulum is:



The length of the leg is approximately the height of the person:

The period is:


The definition of density is
Density = (mass) / (volume)
Multiply each side by 'volume' : (density) x (volume) = (mass)
Divide each side by 'density' : Volume = (mass) / (density)
Scientists have designed solar cells to trap solar energy and convert it to D electrical energy. Its D because converting something has to do with recharging something and electronics have to charge. I hope I helped.
Kinetic energy is energy that is in motion, thats all I remember
