<u>The frequency of the sound</u> determines the pitch .The higher the frequency , the more high pitched it will sound. if the frequency is very low, it will sound very low pitched.
This is affected by motion of a sound source because if the sound source moves faster, this makes the frequency higher( since frequency is the number of waves/revolutions/whatever per second)
So , if for example , the sound source makes 4 vibrations or whatever in a second , it will have a frequency of 4Hz , but if a sound source makes 8 vibrations or whatever in a second , it will have a frequency of 8Hz . And since pitch is determined by frequency , the sound pitch with a frequency of 8Hz will have a higher pitch than sound source with a frequency of 4Hz.
When a swimmer is submerged into the water, the Gravitation energy is transformed into Kinetic Energy instead. Consequently, this also means that when the diver/swimmer chooses to get out of the water and becomes free from the water again, Potential Energy is restored. This is because it allows the swimmer to do further tasks.

The law of conservation of angular momentum.
What is angular momentum?
Angular momentum is the rotational analog of linear momentum in physics. It is a conserved quantity, meaning the total angular momentum of a closed system remains constant. Both the direction and magnitude of angular momentum are conserved.
What is the law of conservation of angular momentum?
The law of conservation of angular momentum asserts that a system's total angular momentum is conserved when there is no external torque present. In other words, the magnitude and direction of the total angular momentum of an isolated system remain constant.
According to the Nebular Theory, the solar system originated as a massive, slowly rotating cloud of gas measuring around one light-year in diameter. As the cloud cooled, its own gravity caused it to collapse. It distorted into a revolving pancake shape due to the conservation of angular momentum, which required it to spin faster as it shrank.
Hence, the law of conservation of angular momentum best explains why the solar nebula spun faster as it shrank in size.

C is the correct answer beacause it shows where it is happening in this cas “here”.
