Solid and liquids are much more denser than gas because their molecules are close to each other and with that the molecules of them can't move that freely unlike the gas molecules. Also, because of being near to each other the molecules of solid and liquids became heavy making them dense.
Answer:
Charge of the alpha particle
Explanation:
Answer:
The elastic potential energy PE=143.47kJ
Explanation:
This problem bothers on the potential energy stored in a material.
Given data
Mass of the bungee jumper
m= 75kg
Height of jump down the cliff h=195m
We know that the elastic potential energy stored is same as the potential energy of the bungee jumper
PE= 1/2kx²= mgh
Assuming g is 9.81m/s²
PE= 75*9.81*195
PE= 143471.25J
PE=143.47kJ
What is potential energy?
Potential energy is the energy possessed by a body by virtue of it position.
