Capacitors work through the build up of current on their two opposing plates. Current in the form of negatively charged electrons builds up on one plate which in turn repels electrons on the other plate m...

As the object leaves the surface of the planet, it loses kinetic energy and gains gravitational potential energy. Through conservation of energy we know the loss of kinetic energy must be equal to the gai...

The horizontal position x (measured from the optical axis) of a point on the screen at distance D from the double slit with slit separation a is related to the angle of diffraction Φ via...

c = EmΔt. With E being the thermal energy during the transfer, m being the mass of the substance, and Δt being the change in temperature.Usually they'll hide one of the values E, m or Δt in a different eq...

This effect is called diffraction. This occurs when waves spread over obstacles or through gaps.
