The fastest nerve signals travel at speeds that exceed 100 meters per second :)
Thermal equilibrium is a state in which all parts of a system are at the same temperature
here force between two particles is given by Coulomb's law where two particles will either repel or attract each other
this force of attraction or repulsion is given by the equation
here we know that
= two point charges
r = distance between two charges
so now we will substitute all values in it
so above is the force between two point charges
The conservation of energy a ball rolling down a hill is that the ball is in motion because it is moving
