Write relation between speed and magnitude of velocity.

Write relation between the magnitudes of shear modulus and Young's modulus.

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?

Write relation between instantaneous and relative velocity for uniform motion.

Write relation between torr and millibar .

A bird files due north at velocity 20 ms^(-1) for 15s it rests for 5s and then files due south at velocity 24 ms^(-1) for 10s. For the whole trip find the average speed and magnitude of average velocity

Write relation between pure water and water potential.

Relation between poise and decapoise.

Write the relation between linear speed and angular speed.
