Answer:

Explanation:
The force is equal to the negative of the derivative of the potential energy function:

In this problem, the potential energy function is

Therefore, the force function is:

So, adding the units of measurement,

Answer:
8.5 ohms
Explanation:
from ohms law
V=IR
120=14.1R
divide both sides by 14.1
120/14.1=14.1R/14.1
R=8.5ohms
A fire because you feed it wood, it lives longer but if you give it a drink, water, then it dies.
