Can average speed and instaneous speed by equal? Explain.

Average speed and instantaneous speed are always equal.(True/ False)

How is average speed obtained ?

How do you distinguish between average speed and root mean square speed of the molecules of a gas?

Define the terms: most probable speed, average speed and root mean square speed. How are these speeds related to each other?

Can a trapezium have all angles equal ? Can it have all sides equal ? Explain .

Obtain the frequency of revolution of the electron in its circular orbit. Does the answer depend on the speed of the electron ? Explain.

In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why ?
