When the temperature of an object increases, what happens to the kinetic energy of the particles in the object?

b. it equals zero.

c. it increases.

d. it decreases.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
