A torsional pendulum is formed by attaching a wire to the center of a meter stick with a mass of 5.00 kg. If the resulting period is 4.00 min, what is the torsion constant for the wire

The torsion constant for the wire is .

Explanation:

The angular frequency of the torsional pendulum (), measured in radians per second, is defined by the following expression:

(1)

Where:

- Torsional constant, measured in newton-meters.

- Moment of inertia, measured in kilogram-square meters.

The angular frequency and the moment of inertia are represented by the following formulas:

(2)

(3)

Where:

- Period, measured in seconds.

- Mass of the stick, measured in kilograms.

- Length of the stick, measured in meters.

By (2) and (3), (1) is now expanded:

If we know that , and , then the torsion constant for the wire is:

The torsion constant for the wire is .

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
