Rock 3, because it has the most mass while still moving at the same speed, it is kinetic because there is movement and energy being used
The electrostatic force between two charges Q1 and q is given by

where
ke is the Coulomb's constant
Q1 is the first charge
q is the second charge
r is the distance between the two charges
Re-arranging the formula, we have

and since we know the value of the force F, of the charge Q1 and the distance r between the two charges, we can calculate the value of q:

And since the force is attractive, the two charges must have opposite sign, so the charge q must have negative sign.
Precipitation from the sky to the earth can come in several forms. Four types are:
1) Rain
2) Snow
3) Sleet (think of a more liquidity slushy snow)
4) Hail (pretty much solid chunks of ice)
the machine shown in the diagram is called a tramp.
the height of the tramp is 5 and the length is 12
It would be A. Because think of the explanations Jasons friend could say to them that would be a negative 'statement'.
