True or False. The mass of the pendulum determines the time of a period.

False

Explanation:

The time period of a pendulum is given by :

The terms used in the formula are :

l is length of pendulum

g is acceleration due to gravity

It is clear that the formula of time period of a pendulum is independent of its mass. So, the mass of the pendulum is not used to determine the time of a period. Hence, the given statement is false.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
