PASCAL'S LAW

 PASCAL'S LAW:

The pressure exerted at any point in a confined liquid is transmitted equally and undiminished in all direction throughout the liquid.

Pressure at a point in a liquid =F/A, Pressure at any other point in the liquid=F'/A'

As pressure is transmitted equally,   F/A=F'/A'

Applications

1.Hydraulic press.

2. Hydraulic lift.

3.  Hydraulic brakes.

UNIFORM CIRCULAR MOTION

In uniform circular motion,  1. Speed is constant. 2. Velocity is variable and acts along tangential direction  at a point. 3. Centripetal Force and acceleration act along the radius towards the centre if the circular path.  4. Centrifugal force appears to  act radially outwards. It is a virtual  ,fictitious force, not a real force.

MIRAGE. HOW IS IT FORMED ?

MIRAGE is formed by the phenomenon of total INTERNAL reflection of light. Mirage is formed in extremely high or low temperature conditions. For example: When a sand surface (desert) or road surface is heated, the air above this surface is also heated and rises up. As a consequence, the density of air in the lower level is less than that of upper level.   Now , the light from any object starting from the upper layers (denser medium) travels to lower layers ( rarer medium), total internal reflection takes place i.e, the light is reflected back towards the denser medium. When these light rays reflected back, it seems that the light rays are refected from some bright reflecting surfaces on the ground.  Hence the  image is seen below the object.
