Answer:
The speed of the animals is 1.64m/s.
Explanation:
Let us work with variables and call the mass of the two rats
and
, and the length of the rod
.
Using the law of conservation of energy, which says the potential energies of the rats must equal their kinetic energies, we know that when the rod swings to the vertical position,

,
solving for
, we get:

Putting in the values for
,
,
, and
we get:


Therefore, as the rod swings through the vertical position , the speed of the rats is 1.64 m/s.
The largest transition metal is copernicium with 112 protons.
Answer:
mass =25 kg
using clockwise moment = anticlockwise moment
Answer:
According to Hook's law, we know,
strain/stress =Constant
Explanation: So, the ratio between stress and strain is always constant.
So, if stress is increased, then strain changes in that way so that this ratio always remains constant.
