### Chabot College Physics Lab Experiment: Balsa Wood in Seawater

In this experiment, a piece of balsa wood is entirely submerged in seawater. The wood is initially at rest and tethered by a string to the bottom of a seawater container. The balsa wood has a volume of \(1.333 \times 10^{-6} \, \text{m}^3\) and a density of \(0.157 \times 10^{3} \, \text{kg/m}^3\). The density of seawater is \(1.023 \times 10^{3} \, \text{kg/m}^3\).

**Questions:**

(a) **Buoyant Force Direction:** What is the direction of the buoyant force acting on the wood, up or down? Circle "up" or "down."

(b) **Tension Force Direction:** What is the direction of the tension force acting on the wood, up or down? Circle "up" or "down"?

(c) **Gravity Force Direction:** What is the direction of the force of gravity acting on the wood, up or down? Circle "up" or "down"?

(d) **Tension Magnitude:** What is the magnitude \(T\) of the tension in the string?

(e) **Upward Acceleration:** Suppose the cord is cut and the tension becomes zero. What is the upward acceleration \(a\) of the object? See Figure 2 for guidance. The first step is to determine the difference between the buoyant force and the weight from the available information. That step provides the net force, and from that, the acceleration follows, in \(\text{m/s}^2\).

### Diagrams Explanation:

- **Top Diagram:** A rectangular container with water is shown. A block representing balsa wood is submerged and tethered by a string, labeled with tension \(T = ?\). The string points downward from the balsa wood to the container’s base.

- **Bottom Diagram:** Similar to the top diagram, but without the string. An arrow pointing upward from the balsa wood block indicates the direction of acceleration \(a\) upon cutting the string.

Both figures are collectively labeled as Figure 2.
