A uranium atom traveling with a velocity of 5.00 x 105 m s-1 relative to the containing tube breaks up into Krypton and Barium. The Krypton atom is ejected directly backwards at a velocity of
2.35 x 106 m s- relative to the barium after separation. With what velocity does the barium atom move
F:
forward relative to the tube? What is the velocity of the Krypton atom relative to the containing
tube?(mass of Kr = 95.0; Ba = 140; U = 235)
Ans: 1.45 x 106 m s-1, 9.0 x 105 m s-1​

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 !
