2) A car starting from ret accelerate uniformly A and attain a speed of soms to 30seconds. It maintains t in steady speed for another 30 Seconds-It then slows de Unsformly until it comes to rest is the next 40 secor graph for the moties gloph determine; tine a) sketch the velouty 6 from the Its acceleration Decceleration 1. 11) The total distance covered by the car

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

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 !

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
