The human small intestine moves food along its 6.9- m length by means of peristalsis, a contraction and relaxation of muscles that propagate in a wave along the digestive tract. part a if the average force exerted by peristalsis is 0.18 n , how much work does the small intestine do to move food along its entire length?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
