When an atom has a high neutron-to-proton ration, that atom is very unstable and thus, radioactive. The more neutrons an atom has, the more radioactive it is. So,it is only logical that the element with the greatest number of neutrons is Uranium. It has 140 neutrons.
Answer:
Explanation:
momentum is written as p
p = mass * velocity
p = mv
30 km per hr = 30 * 1000 meters per 3600 seconds
velocity = 30000 meters per 3600 seconds
p = mv
p = 75 * 30000 / 3600
p = 625 kilogram per meter second
