A student drops a bowling ball and an apple from a third-story window. Both objects hit the ground at the same time. From the experiment, the student should conclude that

• the apple weighs more than the bowling ball

• more air friction is acting on the apple than on the bowling ball

• gravity pulls on both objects, causing them to fall at the same time.
