Answer: he ran with the most energy from the first to the second point…(2.1 m/s - 4.5 m/s)
Explanation:
Answer:
It would be lower than because, if the boiling point of that element is 77 Kelvin degrees then if it isn’t at boiling point it would automatically be cooler than that. Even if it’s at its original state. The normal temperature of Liquid Nitrogen is really cold -320.8 degrees.

The source of this energy is from the release of gravitational energy as the protostar continues to shrink.
<h3>How are stars born and what is a protostar?</h3>
Nebulae have as possible differences in gas and dust. Some factors, such as turbulence, can cause one of them to contract. This contraction of the set of materials causes the elaboration and execution of this phase of materials, generating what is usually called, in this protostar.
A protostar is formed by the contraction of a giant molecular cloud in the interstellar medium. Stars form within relatively dense concentrations of interstellar gas and dust known as molecular clouds.

Answer:
The correct answer is C , because it increases and decreases
Explanation:
Reference frames describe the position of points relative to the body. These frames <span>are used to specify the relationship between a moving </span>observer and the phenomenon or phenomena under observation. Reference frame definitely changes when the body is changing. That is the reason that in order t<span>o describe the position of a point that moves relative to a body that is moving relative to the Earth, it is usually convenient to use a reference frame attached to the moving body.</span>
