kvasek [131]

NO. Since "c" has no dimensions, the value of its exponent "n" is irrelevant to dimensional analysis, and thus dimension analysis cannot be used to determine the value of "n".

Dimensional analysis is not applicable to proportionality constants, trigonometrical or exponential equations, equation consisting of sum or difference of some quantities and equation consisting of more than three fundamental quantities.

What is Dimensional analysis?

Dimensional Analysis is a problem-solving technique that makes use of the fact that any number or expression can be multiplied by one without changing its value.
It is also known as the Factor-Label Method or the Unit Factor Method. It is a practical method.

What is a dimensional analysis used for?

Dimensional analysis is a method used in engineering and the physical sciences to reduce physical properties like acceleration, viscosity, and energy to their three basic dimensions of length, mass, and time (T).

The force between two very small charged bodies is found to be F. If the distance between them is tripled without altering their

SpyIntel [72]

Answer:

if the old force is F, the new force is F/9

Explanation:

Recall that the Coulomb force between to charges is inversely proportional to the square of the distance between the charges.

Therefore, if the original distance "d" changes now to be "3d" (tripled), the denominator of the force expression will change from:
