Question 46

What happens with things like liquids "falling" onto objects like sponges? Does the sponge exert an upward force onto the liquid?
When liquids fall onto sponges, the sponges do exert upward forces on the liquids. Otherwise, the liquids would continue to fall. When a raindrop hits your hair, you can feel it push on your hair and your hair pushes back, stopping the raindrop's descent.
