For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

If you put a helium-filled balloon in the refrigerator, what will happen?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
