Your friends sit in a sled in the snow. if you apply a force of 120 n to them, they have an acceleration of 1.3 m/s^2.what is their mass?

Mass of the sled, m = 92.30 kg

Explanation:

It is given that, your friends sit in a sled in the snow.

Force applied on the sled, F = 120 N

Acceleration,

We need to find the mass of the sled. The force acting on the sled is equal to the mass of the sled and the acceleration produced i.e.

m = 92.30 kg

So, the mass of the sled is 92.30 kg. Hence, this is the required solution.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.
