Specific Heat Capacity is the amount of energy required to increase the temperature of 1kg of a substance by 1 degree Kelvin/Celsius ."Specific" refers to the fact that this value is per kilogra...

total resistance for resistors in series is the addition of the resistances therefore the two 3 ohm resisters in series totals 6 ohms resistors in parallel follow the equation : 1/R_T = 1/R_...

The work function of a metal is the minimum amount of energy required for electrons to start escaping the surface. This means that if we calculate the energy of each photon from the light and subtract the...

Both the speed and the velocity show us how fast something is moving (the rate at which it changes its position). However, velocity is a vector quantity, which means it also gives us information about the...

1. Think of key words in the questions to help solve it. For example in this question we need to consider density and the fact that the object is a cube. 2) Remember the equation of dens...
