maxwell law of molecular velocities

We have, Applying the law of parallelogram of vectors, Since, This equation gives the magnitude of the resultant velocity of the projectile at any time. The direction of the projectile is given by the angle equation, which the resultant velocity v makes with the horizo..

Expression for Velocity Vector - The curved line in the figure represents the trajectory of a particle. Let the particle be at P at time t. The position of p with reference to origin O is given by . Let the particle be at Q at time (t + D t). The position of Q with reference to P is given..

Consider an object of mass 'm' placed on the surface of the earth. According to Newton's law of gravitation, the gravitational pull of the earth on that object is given by Where F is the force of attraction between the earth and the object, M e is the mass of the earth and R e is the radi..

Stokes' Law - When small spherical bodies move through a viscous medium, the bodies drag the layers of the medium that are in contact with them. This dragging results in relative motion between different layers, which are away from the body. Therefore, a viscous drag comes into play, oppo..

When more than one type of molecule is present (at constant T) then, the total pressure exerted by the mixture should be equal to the sum of their individual pressures when present alone. The pressure exerted by each gas is..

. Thus, the gas gains energy as heat gets supplied to it and it loses energy as work is done by it. Suppose, in a process, an amount D Q of heat is given to the gas and an amount D W of work is done by it, the total energy of the gas must increase by ( D Q - D W). As a result, the entire gas, toget..

We know that the properties of a medium that govern the propagation of a mechanical wave are: a restoring force an inertial mass The restoring force acting on the particles of the medium is intimately connected to the approximate elastic modulus of the medium and the inertial mass, to its density. ..

Let m be the mass of a body in an orbit of radius r, velocity v and angular velocity ' w '. the centripetal force If T is the time period then, According to Kepler's third law, ..

Action and reaction forces result in change in velocities of both the bodies which in turn change the momenta of these bodie..

Stokes' law explains why the speed of a raindrop is less than a freely falling body with constant velocity, from the height of clouds. The same law helps a man coming down with the help of a parachute, to slow down. Terminal velocity refers to the consta..
