Answer:
Use F = m*a
Explanation:
If you are given the mass of the two different bodies, you could rearrange these equations, plug in the mass of the unknown body to find the unknown force
Answer:
D. 2.5 V
Explanation:
Electric potential of a point in space is a scalar magnitude that allows a measurement of the electric field at that point to be obtained through the electrostatic potential energy that a electric charge would acquire if it is placed at that point.
Your average speed was
(100 m) / (13.8 s) = 7.25 m/s .
If you finished 0.001s ahead of him, then at your average speed, that corresponds to
(7.25 m/s) x (0.001 s) = 0.00725 m
That's 7.25 millimeters ... about 0.28 of an inch !
NOTE:. I think this is only valid if your speed was a constant ~7.25 m/s all the way.
It would be 22 depths inside the glass of water.
