Q. Given a global mean vertical latent heat flux at the surface of 80 W/m^2 , what is the globally averages rate of evaporation in terms of depth of water per year?

Q. An 8.0 m, 200 N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.55, and the ladder makes a 50.0° angle with the ground. How far up the ladder can an 800 N person climb before the ladder begins to slip?
