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​

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
