Ou are to drive to an interview in another town, at a distance of 300 km on an expressway. the interview is at 11: 15 a. m. you plan to drive at 100 km/h, so you leave at 8: 00 a. m. to allow some extra time. you drive at that speed for the first 100 km, but then construction work forces you to slow to 40.0 km/h for 43.0 km. what would be the least speed (in km/h) needed for the rest of the trip to arrive in time for the interview?

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 !

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction. true or false?
