Answer: D) Mass, speed and radius all impact the centripetal force
Explanation:
If we change either the mass, speed, and/or radius, then the centripetal force will be different. Though on rare occasions we could change the variables together in a way to have the centripetal forces line up, but in general the before and after forces will likely be different. Changing one variable at a time only will definitely result in a different centripetal force.
This is because the centripetal force F is determined by the formula
F = (m*v^2)/r
where,
m = mass
v = velocity
r = radius
