Question

Математический маятник совершил 100 колебаний за 628 с. Чему равна длина нити маятника?

Answer 1

там все есть..дано и все такое..

Answer 2

Calculating the Length of the Pendulum

To calculate the length of the pendulum, we can use the formula for the period of a pendulum, which is given by:

T = 2π√(l/g)

Where: - T = period of the pendulum - l = length of the pendulum - g = acceleration due to gravity

Given that the pendulum completed 100 oscillations in 628 seconds, we can use this information to calculate the length of the pendulum.

Using the Period Formula

We can rearrange the formula for the period of a pendulum to solve for the length l:

l = (T^2 * g) / (4 * π^2)

Where: - T = period of the pendulum (in seconds) - g = acceleration due to gravity (approximately 9.81 m/s^2)

Calculation

Using the given values: - T = 628 seconds - g = 9.81 m/s^2

We can calculate the length of the pendulum using the formula: l = (628^2 * 9.81) / (4 * π^2)

Result

Calculating the above expression gives us the length of the pendulum.
