By definition we know that Force is equal to mass by acceleration F = m * a. Also, by definition acceleration equals velocity between time a = v / t. Therefore, the expression for the force will be given by: F = m * (v / t). Substituting the values: F = 17 * (6/3) = 34N. The force is 34N

Two particles with charges are initially very far apart (effectively an infinite distance apart). They are then fixed at positio
ddd [48]

Answer:

potential energy increases.

Explanation:

The potential energy between the two charged particles is given by

U = k Q q / r

If they are very far apart then r tends to infinity and the potential energy is zero.

If they come closer then the potential energy between the two charged particles increases.

Thus, the potential energy increases.

What factors affect the speed of water waves
Aneli [31]
Hey there,

Your question states: What factors affect the speed of water waves
Let's get one thing out the way, (wavelength) does NOT affect the the speed of water. If anything, it would be how high the wavelength's are. The higher the wavelengths are, the more that it would affect the speed, because there very high, but if it were to go longer on the width side, that would increase the speed, but that's not the case. Your correct answer would be (higher wavelength).

Hope this really helps you.
