Suppose two cylinders of equal size and diameter are connected by a hollow tube and filled with a liquid. Inside these two cylinders are equal-sized pistons. If one of the pistons is pressed down, the liquid will transfer the force and motion to the other piston, moving it A. half the distance with an unequal amount of force. B. twice the distance with an equal amount of force. C. an unequal distance with an equal amount of force. D. an equal distance with an equal amount of force.

Mike · Answer 1

The answer is D. an equal distance with an equal amount of force.

This is because the two cylinders have the same diameter and the liquid inside them will not compress. So when one of the pistons (both pistons are also equal size) is pressed, the same amount of liquid is moved from one to another.
