Final answer:
The period of a pendulum with the axis placed at the end of a 104-cm measuring stick can be calculated using the formula for a simple pendulum using half of the total length, since the center of mass is at the midpoint.
Step-by-step explanation:
The period of a pendulum when the axis is placed at the end of the measuring stick, which is 104 cm (or 1.04 meters) long, can be calculated using the formula for the period of a simple pendulum: T = 2π√(L/g), where T is the period, L is the length from the pivot to the center of mass, and g is the acceleration due to gravity which is approximately 9.81 m/s² on the surface of the Earth. Assuming the measuring stick is uniform, the center of mass will be at its center. Since the axis is placed at the end of the stick, the pendulum behaves as a physical pendulum where the distance to the center of mass is half the length of the stick. Therefore, we calculate the period by substituting L = 1.04/2 = 0.52 m into the formula to find T.
The calculated period (T) will indicate how long it takes the pendulum to complete one full oscillation back and forth.
