When administered to a normally hydrated patient, isotonic solutions have what effect?

Match the type of fluid with its classification.

A linear graph of r vs s2 is plotted for the equation , 

If a mass of 100 g is able to extend a spring by 4 cm, the spring constant will be

A 2 kg mass moving along a straight line with 5 m/s, strikes to a 3 Kg mass at rest. If the collision has 0% elasticity, the final speed of the 2 kg mass is

If the spring constant of a spring in 60 N/m, and one unknown mass suspended on it was able to extend the spring by 25 cm. The unknown mass will be 

If you suspended a mass of 875 g on one side of a balanced meter stick (at its center of gravity) at 45 cm from the center of gravity. How much force do you need on the opposite side of the meter stick at 25 cm from the center of gravity to have the equilibrium condition?
