A 70 kg block is pulled up a 25o slope by an applied force F = 500N as shown in the figure below. At point A of the incline, the speed of the block is 3.6 m/s. The block accelerates up the rough slope with the coefficient of kinetic friction μ = 0.25 between the block and the surface. Ignoring the air resistance, determine the following

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 !
