I really need help

Around faucet handle is part of a(n) a. lever b. screw c. inclined plane d. wheel and axle

In the first law of thermodynamics, triangle e=q-w, what does q stand for

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.
