Question

A grandfather clock depends on the period of a pendulum to keep correct time. Suppose a grandfather clock is calibrated correctly and then a mischievous child slides the bob of the pendulum downward on the oscillating rod. The grandfather clock will run:

Answer 1

The grandfather clock will run: slower

Explanation:

A grandfather clock depends on the period of a pendulum to keep correct time. Suppose a grandfather clock is calibrated correctly and then a mischievous child slides the bob of the pendulum downward on the oscillating rod.

A pendulum is a weight that get suspended from a pivot, therefore it can swing freely. A pendulum clock is the clock using a pendulum, a swinging weight, as its timekeeping element.

Calibrate in physics means to ascertain the caliber of and to determine, rectify, or mark the graduations of something, such as a thermometer tube.

A bob is the weight located on the end of a pendulum found in pendulum clocks.

The time period of simple pendulum is given by:

$T = 2 \pi \sqrt{\frac{L}{g} }$

The time period of a simple pendulum is defined as the time taken by the pendulum to finish one full oscillation.

Where l is the effective length of the pendulum, and g is the acceleration due to gravity

The grandfather clock will run: Slower. Because as the length of the pendulum increase, the tie period of the pendulum also increase.  It means the clock run slow.

Answer 2

Answer:

Slow

Explanation:

As we know that the time period of simple pendulum is given by

$T = 2\pi \sqrt{\frac{L}{g}}$

Where, l be the effective length of the pendulum and g be the acceleration due to gravity

As the length of the pendulum increase, then the tie period of the pendulum will also increase.

It means the clock run slow.
