HELP QUICK A 1 kg bird is sitting in a tree 20 meters tall. Thebird leaves its nest and flies away at a velocity of 3 meters per second. Calculate the bird’spotential energy when it is sitting in the tree and its kinetic energy when the bird fliesaway.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
