Question

Виміряйте довжину нитки L маятника

Answer 1

Measuring the Length of the Pendulum Thread (Виміряйте довжину нитки L маятника)

To measure the length of the pendulum thread (L маятника), we can use the formula for the period of a pendulum, which is given by:

T = 2π√(L/g)

Where: - T is the period of the pendulum - L is the length of the pendulum thread - g is the acceleration due to gravity

By rearranging the formula, we can solve for the length of the pendulum thread (L):

L = (T/2π)^2 * g

Now, let's assume the period of the pendulum (T) is known and the acceleration due to gravity (g) is approximately 9.81 m/s^2.

Using this information, we can calculate the length of the pendulum thread (L) using the provided formula.

Calculation

Using the formula L = (T/2π)^2 * g and assuming the period of the pendulum (T) is 1 second, we can calculate the length of the pendulum thread (L):

L = (1/2π)^2 * 9.81 L ≈ 0.250 m

So, the length of the pendulum thread (L маятника) is approximately 0.250 meters.

Please note that the actual period of the pendulum and the local acceleration due to gravity should be used for precise measurements.
