In solving this, the ideal gas law must be considered (pV=nRT). Since both the pressure and volume of the gas have doubled, the product p*V (pressure times volume) has increased four times from the initia...
It's important information as it tells you how fast light travels through the material. This can give you an insight into how the angle of refraction of the light is related to the angle ...
Acceleration is defined as the rate of change of velocity. The important thing to realise here is that velocity is a vector quantity while speed is a scalar one. An object going in circular motion has con...
Power stations use step-down transformers to decrease the voltage of the electrical output. The power lines have a constant resistance (say, R Ohms) which means there is a power loss across the lines give...
The kinetic theory models gas particles as points moving around with a given velocity. Heating the particles causes the transfer of heat energy, which is then used to increase the particles kinetic energy...
