A0.57 kg rubber ball has a speed of 1.2 m/s at point a and kinetic energy 7.5 j at point b. find a) the ball’s kinetic energy at a.(b) what is its speed at point b? (c) what is the total work done on the particle as it moves froma to b?

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?

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 !

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is
