Answer:
fog and mist are the examples
There are a lot of same examples that you may have worked before, where the mass on a spring uses a classics when it comes to mechanics. So in this system, always put in your mind that there is an enormous quantum standard that one can use in the equation. It should be 2.10x10 raise to a negative sixth. J.
Answer:
The magnitude of the force is 1.29*10^-3N in the positive x direction
Explanation:
In order to calculate the magnitude and direction of the force, you take into account that the force is the space derivative of the potential enrgy, as follow:
(1)
where:

You replace the expression for U into the equation (1) and solve for F:
(2)
The force on the particle, for x = -0.080m is:

The magnitude of the force is 1.29*10^-3N in the positive x direction
1 watt = 1 joule per second
1 joule = 1 newton-meter
1 newton = 1 kg-meter per second²
Put it all together and you have . . .
1 watt = 1 <em>kg-meter² / second³
