What is the relation of physics to biology?

Write an expression for an acceleration rectangular components.

An artificial satellite of mass 3000 kg is orbiting around the earth with speed of 4500 ms^-1 at a distance of 10000 km from the earth. Calculate the centripetal force acting on it.

A block of mass 5 kg is placed on the floor, the coefficient of static friction is 0.6. A force of 3.8 N is applied on the block. Find the force on friction between the block and the floor.

A force of 36 dynes is inclined to the horizontal at an angle of 60°. Find the acceleration in a mass of 18 g that moves in a horizontal direction.

How high must a body be lifted to gain an amount of P.E. equal to the K.E. it has when moving at speed 20 ms^-1. (The value of acceleration due to gravity at a place is 9.8 ms^-2).

Distinguish between static and dynamic equilibrium.

A Geo-stationary satellite bits around the earth in a circular but of radius 36,000 m then what will be the time period of a specially satellite orbiting a few hundred km above the earth's surface (R_earth = 6400 km)

A cylinder with a movable piston contains 3 moles of hydrogen at constant temperature and pressure. The walls of a cylinder are made up of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of a gas increases if the gas is compressed to half its original volume?

How are sound waves-classified?
