A66-foot-tall woman walks at 55 ft/s toward a street light that is 2424 ft above the ground. what is the rate of change of the length of her shadow when she is 19 ft19 ft from the street light? at what rate is the tip of her shadow moving? let l be the length of the woman's shadow and let x be the woman's distance from the street light. write an equation that relates l and x.

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 !
