Chapter 12.2, Problem 4cT
A third block, C, of the same size and shape as A and B but with slightly greater mass thanblock B is released from rest at the center of the beaker. Two students predict the finalposition of the block and draw the sketch at right.
| Student 1: | Since this block is heavier than block B, it will not go up as high after it is released, as shown at right. |
| Student 2: | Yes, I agree, the buoyant force is slightly less than the weight of this block, so it should come to rest a bit below the surface. |
Explain what is wrong with each statement and with the diagram.

The figure below depicts a ball in flight. The direction of the airflow is indicated by the stack of straight arrows pointing to the right towards the ball. The linear velocity of the ball is indicated by the
vector, VB. The curved arrow represents the direction of rotation of the ball. What direction will the Magnus force act (i.e., which direction will the ball be pushed due to its interaction with the fluid
flow)?

TRUE OR FALSE. On the answer sheet, shade the circle for Letter A if the statement is correct.
Otherwise, shade the circle for Letter E.

1. Boat floats because there is a force that is pushing it up.
2. Only the weight of the object determines if the object will sink or float.
3. If I change the shape of the clay, its weight and volume also change.
4. Cutting a wood in half will also make its density half of the original density.
5. The pressure exerted by the fluid at rest on an object is directly proportional to the density of the liquid
and depth and is sometimes called as gauge pressure.
The mechanism shown in (Figure 1) is used in a riveting
machine. It consists of a driving piston A, three links, and a
