Question

Define heat...and angle of friction?​

Answer 1

Step-by-step explanation:

Heat is the form of energy that is transferred between systems or objects with different temperatures.....

Angle of friction : The angle which the resultant of force of limiting friction F and normal reaction R makes with direction of normal reaction R is called angle of friction...

Answer 2

physics the angle of a plane to the horizontal when a body placed on the plane will just start to slide. The tangent of the angle of friction is the coefficient of static friction.
