which is one kind of evidence that work is done on an object?
a. the object stays in one place.
b. the object moves some distance.
c. the object has a force on it.
d. the object changes shape.

B. The object moves some distance

Explanation:Work is the product of force and distance.Work is done on an object when a force is applied on the object making it move some distance.For example; If a mason applies a force of 5 N to move a stone at a distance of 10 m, then the work done will be 50 Joules.Applying a force on an object without making it move some distance then there is no work done.Consider a boy pushing a wall really hard and the wall doesn't move even for a single inch, this means there is no work done.

No. an alpha particle is a pair of protons and a pair of neutrons, i.e. a helium
