If an unbalanced force applied to an object doubles, then
A)its velocity doubles.
B)its acceleration doubles.
C)its acceleration is cut in half.
D)its acceleration increases by a factor of four.

According to Newton's Second Law, force is directly proportional to acceleration. Therefore, if the force doubles, the acceleration would also double. Velocity is dependent on both force and time, so it may or may not change depending on the specifics of the situation. The other choices are not correct because the acceleration would not be cut in half, nor would it increase by a factor of four as a result of a doubling of force.
