Nuclear chosen would be the gamma because it’s the one choose to be radioactive more than others
Answer:
Gravity Force
Gravity Force(also known as Weight) The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object <em><u>your welcome </u></em>
We start from the definition of Torque,

Where ,
I = moment of inertia
Angular acceleration.
The torque given in the problem is 1.96mN.
We look for the moment of inertia of a solid cylinder,

Where m is the mass of 4Kg and R the radius 0.035m


Replacing,

A) With angular acceleration we can find the number of revolutions, the given equation would be,




B) We apply the rotational dynamics formula and we can find the time,
