Effect of temperature on Velcoity of sound:
Velocity of sound in gases depends upon the square root of the absolute temperature.
Newton second law of motion states that " Rate of change of momentum of an object is directly proportional to the force acting on it
Derivation:
From Second law :Fαdp/dt
Fαdm(v-u)/dt
Fααmd(v-u)/t [ as mass is constant]
Fαma [since a= v-u/t]
F=kma
where k is proportionality constant
assuming K=1 when F=1N a=1/ms2 and m=1kg
∴F=ma
