Answer:
Height, h = 16.67 m
Explanation:
We have,
Mass of a squirrel is 0.765 kg.
He jumps off the tree and hits the ground with 125 joules of energy.
It is required to find the height up on the tree the squirrel was when it jumped.
The energy possessed by the squirrel is called its gravitational potential energy. It can be given by :
h is height up on the tree the squirrel was when it jumped
So, the squirrel will go to a height of 16.67 m.
Anytime that an unstable nucleus emits alpha or bets particles, the number of protons and neutrons changes. ... In the fission process, when the nucleus splits, both neutrons and energy are released
