Whilst in the boat the rock (and you) are floating, this means that the amount of water displaced by the rock is the mass of the rock. When the rock sinks to the bottom of the lake the amount of water dis...
The electromotive force and the potential difference in a circuit are very similar concepts as they are both names for energy per unit charge within a circuit and they both use the same unit, Volts. The d...
The kinetic energy of the electron will be equal to the energy what the electric field gives to it.1/2mv2=VQFrom thisv=sqrt(2VQ/m)De Broglie wavelength:lambda=h/p=h/...
When the driving force occurs at the natural frequency of the system (the natural frequency being the frequency if the system were oscillating freely) there is maximum energy transfer to the system causin...
Ice, in it's solid form, is at a maximum temperature of zero degrees Celsius. You might expect that a small volume of Ice might cool say a 25 degree drink to somewhere halfway between 0 and 25. This is no...
