PHYSICS

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.

Heat capacity depends on mass. More the mass of a substance, more is the heat capacity. That's why the cooking vessels have thick bases to absorb more heat and to tranfer more heat to the food for longer period of time.
