| **The mathematical pendulum performs free oscillations in a carriage that is uniformly moving relative to the Earth. The period of its oscillations is equal to T. What will be the period of oscillations of this pendulum in a car stationary relative to the Earth?**

Because in both cases, we are talking about inertial reference systems, then the periods of oscillation of the pendulums will be the same and equal to T.
