**Question 3:** You notice that your favorite pendulum clock is running too slow. Which of the following adjustments of the weight would make it more accurate?
- **A) Raise the weight.**
- **B) Lower the weight.**
- **C) Add more mass to the weight.**
- **D) Remove some mass from the weight.**
- **E) Increase the amplitude of swing by a small amount.**
In the provided illustration, there is a simple drawing of a grandfather clock, which includes a clock face at the top and a pendulum weight at the bottom.
**Explanation of Options:**
Option A) Raising the weight would generally make the clock run faster. This is because raising the weight effectively shortens the length of the pendulum, thereby increasing the frequency of its swing.
Option B) Lowering the weight would make the clock run slower since it increases the effective length of the pendulum, reducing the frequency of its swing.
Option C) Adding more mass to the weight does not affect the period of the pendulum’s swing in an ideal pendulum. The period is only dependent on the length of the pendulum and the acceleration due to gravity.
Option D) Removing some mass from the weight would also not affect the period of the pendulum for similar reasons mentioned in option C.
Option E) Increasing the amplitude of the swing might have a slight timing effect for very large angles due to the nonlinear nature of large pendulum swings, but this is typically a minor effect and not a standard adjustment method for accuracy.
**Correct Answer:** **A) Raise the weight.**
Raising the weight shortens the pendulum's effective length, increasing the swing frequency and making the clock run faster, thus correcting the slow running.
