1. which combination of forces would cause the boat to sink?

a. force of water = 500n and force of masses = 500n
b. force of water = 500n and force of masses = 400n
c. force of water = 500n and force of masses = 300n
d. force of water = 500n and force of masses = 600n

Explanation:

Step1: Recall floating - sinking condition

A boat floats when the upward force of water (buoyant force) is greater than or equal to the downward force of masses (weight). It sinks when the downward force of masses is greater than the upward force of water.

Step2: Analyze Question 9

For the boat to float, the force of water should be at least equal to the force of masses. Among the options, only in option a where force of water = 500N and force of masses = 500N satisfies this condition.

Step3: Analyze Question 10

For the boat to sink, the force of masses should be greater than the force of water. In option d, force of water = 500N and force of masses = 600N, which satisfies this condition.

Answer:

1. A. Force of water = 500N and force of masses = 500N
2. D. Force of water = 500N and force of masses = 600N
