In a waterfall, water falls 100 ft. Assume all the potential energy change increases its enthalpy (or internal energy, in this case they change by the same amount because this is an incompressible liquid). Assume the specific heat capacity for water is equal to 1.0008 Btu/(lbm·°F). Calculate the temperature rise of the water in °F. (6 points)

Which features on mars point to the possibility of liquid water on the planet? impact craters with sharp rims volcanic cones with craters gullies and stream-like channels mountain ranges with faults

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.
