Question

Математический маятник совершает колебания с периодом Т=0,3c. Определить длину нити маятника. Ускорение свободного падения считать равным 10 м/с2 Ответ записать в см.​

Answer 1

Формула периода колебаний математического маятника:
T=2π$\sqrt{l/g}$

Откуда $l=T^{2}*g /$2π=0.3^2*10/2*3.14=0.143 м

Answer 2

Calculation of the Length of the Pendulum

To determine the length of the pendulum, we can use the formula for the period of a pendulum:

T = 2π√(L/g)

where: - T is the period of the pendulum, - L is the length of the pendulum, and - g is the acceleration due to gravity.

Given that the period of the pendulum is T = 0.3 seconds and the acceleration due to gravity is g = 10 m/s^2, we can rearrange the formula to solve for L:

L = (T^2 * g) / (4π^2)

Substituting the given values, we have:

L = (0.3^2 * 10) / (4π^2)

Now, let's calculate the length of the pendulum using the given values.

Using the formula, we find that the length of the pendulum is approximately 15 cm.
