This is a proton decaying into a neutron and two other subatomic particles. Here you have to consider various conservation laws, including: baryon number, lepton number and charge. (Energy and momentum ar...

A) 75 rad/s      B) 150 rad/s      C) 270 rad/s      D) 540 rad/s       Identify equation as w=v/r      Diameter = 0.4m  Radius  = half the diameter = 0.2m       Velocity needs to be in m/s so 108km/h = 1...

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...
