Answer:
C. Reciprocity law
Explanation:
The reciprocity law is based on the assumption that the density or blackening of a photographic film is dependent merely on the exposure or quantity of radiant energy which the film absorbs and is independent of the rate at which the energy is applied.
This law pertains to the milliampere-seconds in the sense that all combinations of milliamperes and time that amount to an equal quantity will produce the same amount of radiographic density.
The answer is:
C. Reciprocity law
A scalar or scalar quantity in physics is a physical quantity that can be described by a single element of a number field such as a real number, often accompanied by units of measurement. A scalar is usually said to be a physical quantity that only has magnitude and no other characteristics.
B is the only answer that makes sense.
A that would mean the car only moves 5 mi/hr
C just doesn't make sense
D the equation never mentions the velocity changing
<h3>Answer;</h3>
<em>Energy is transferred.</em>
<h3>Explanation;</h3>
- Work is the force applied over a given distance, in other words work is the product of force and distance. That is; Work = force × distance.
- Work is measured in Joules.
- Energy on the other hand, is the ability to do work.
- According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.
