Sea Breeze...How is it formed?

theloveforphysics

Water has higher specific heat capacity* than that of land(sand) due to which water is heated at slower rate than the land. As the land is heated, the hot air above the land rises up  creating low pressure above the land. As the air above water is comparatively cooler than the air above the land , this air moves towards the land due to the pressure difference. This cool breeze blowing towards the land from sea is called sea breeze.

As heating is required for its formation,  sea breeze blows during day time.

* Specific heat capacity is the amount of heat required to raise the temperature of unit mass of a substance by 1 K or 1°C.

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.

ECHO IN LIVING ROOM

Why is echo not heard in our living rooms? To hear echo, the minimum distance between the source and the reflector must be 17m. When this distance is more than 17m, the reflected sound can be distinguished from the original. As the length of our rooms is less than 17m, we don't hear echo.
