A forest has a reflectance of 0.15 at a wavelength of 0.55 microns. If the sun is at an angle of 60 degrees from the vertical and the solar intensity at the surface is 1200 W/m2 , how much light is being reflected from the forest

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
