**Question 2: Tension in a String with a Fixed Pulley**A rock is suspended by a string wound around a fixed pulley. The rock accelerates downward. Which one of the following statements concerning the tension in the string is true?**Answer Options:**(a) The tension is greater than the mass of the rock.(b) The tension is less than the mass of the rock.(c) The tension is equal to the weight of the rock.(d) The tension is greater than the weight of the rock.(e) The tension is less than the weight of the rock.---**Explanation:**When analyzing the problem, we consider the forces acting on the rock:1. **Gravitational Force (Weight of the Rock)**: This force acts downward and is equal to the mass of the rock (\(m\)) multiplied by the acceleration due to gravity (\(g\)). \( \text{Weight} = mg \)2. **Tension in the String**: This force acts upward.Since the rock accelerates downward, we know that the net force on the rock must also be downward due to Newton's Second Law. The tension in the string is not enough to completely counterbalance the weight of the rock. Therefore, the tension in the string is less than the weight of the rock. Thus, the correct statement is:(e) The tension is less than the weight of the rock.

If you want to move a wooden crate along the ground, you will need to apply a force to get it started and to keep it moving. This is because there is a force exerted by the ground on the crate, parallel to the surface of the ground that opposes motion or attempted motion. This parallel force between surfaces in contact is called the friction force Ff. Make a few predictions: Q13 A wooden crate is sitting at rest on a horizontal table. There is no attempt to move it. Is there a friction force between the block and the table? Q14 Now suppose that you pull on a string attached to the crate, harder and harder, and the crate doesn't move because the friction force opposes your pull. As you pull harder, does Fr increase, decrease, or remain constant? Q15 Now suppose that you pull hard enough that the crate breaks free and moves along the table. Based on your everyday experience, is the force needed to almost get the crate sliding with constant velocity generally greater than / less than /…
