Which fundamental force causes some forms of radioactivity? a. gravity b. electromagnetic force c. strong nuclear force d. weak nuclear force?

Hello.

The answer is: D. weak nuclear force.

The weak force causes beta decay, a form of radioactivity. It could not be explained by the strong nuclear force, the force that’s responsible for holding the atomic nucleus together, because this force doesn’t affect electrons.

It couldn’t be the electromagnetic force, because this does not affect neutrons, and the force of gravity is far too weak to be responsible.

Have a nice day

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
