Consider a balloon filled with 1 liter of water (1000 cm3) in equilibrium in a container of water, as shown in Figure 1.
e. Discuss with your partner where these two vectors should be drawn on Figure 1: one for the weight of the balloon and the other for the buoyant force that acts on it. How do the size and directions of your vectors compare? |
Refer to the following information for the next five questions.
As a thought experiment, pretend we could remove the water from the balloon but still have it remain the same size of 1 liter. Then inside the balloon is a vacuum.
Refer to the following information for the next six questions.
Assume the balloon is replaced by a 0.5-kilogram piece of wood that has exactly the same volume (1000 cm3), as shown in Figure 2. The wood is held in the same submerged position beneath the surface of the water.
Refer to the following information for the next six questions.
Repeat parts a through f in the previous question for a 5-kg rock that has the same volume (1000 cm3), as shown in Figure 3. Assume the rock is suspended in the container of water by a string.
