It is A. Number of neutrons can differ with and be the same any given element.

Explanation:
According to the law of conservation of energy
,
Potential energy = kinetic energy
I =
mgh =
v = 7.4 m/s
thus, we can conclude that the translational speed of the cylinder when it leaves the incline is 7.4 m/s.
Dredging is what the inventor of this machine need to know while developing the machine.
Hope this helps!
