Using conservation of energy i.e calculating the total kinetic and potential energy at a trivial point, then solving for the velocity at the point in question by knowing the potential energy of the partic...
Gravitational Potential Energy is the work done in moving a mass from infinity to a point in a gravitational field. On the other hand, Gravitational Field Strength is the force exerted per unit mass on a ...
The electric potential at a point in an electric field is the work done per unit charge when a point positive charge is moved from infinity to the point.
Use energy difference between ground and first level to find E1-E0. Energy of the electron a nth energy level is found using En = (n^2pi^2hbar^2)/2mL^2Where n is the energy level plus 1, pi and h...
Current is a measure of the rate of change of charged electrons going through the wire. Therefore, when the current increases more electrons are passing through the wire in a unit time. Thus, their averag...
