The very first scientist was galileo and was the very first person to know the speed of light
A. momentum = mass x velocity
b. kinetic energy = 1/2 x mass x velocity^2
Although total momentum is conserved, total kinetic energy is not necessarily equal. It’s because Jay acted a force on the skateboard and increased the energy of the system.
Answer:
The permittivity of rubber is 
Explanation:
From the question we are told that
The magnitude of the point charge is 
The diameter of the rubber shell is 
The Electric field inside the rubber shell is 
The radius of the rubber is mathematically evaluated as

Generally the electric field for a point is in an insulator(rubber) is mathematically represented as
Where
is the permittivity of rubber
=> 
=> 
substituting values
