12 kg-m, calculate the angular acceleration if the rod in the previous problem has a moment of inertia, i caused by these torques. 19. a 6n force and a 15 n force act on an object. the moment arm of the 6 n force is 0.4 m. if the 15 n 20. force provides 5 times the torque of the 6 n force, what is its moment arm?

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 !
