Random but important stuff from Physics for the Entry Test Preparation.

Molar Specific Heat Constant= molar specific heat at constant pressure divided by molar specific heat at constant volume.

velocity, v is always less than ^/ 2gh due to viscosity of liquid.

I=Intensity is equal tp pressure by Area, with units Watt per square meter and Joule per meter squared into second.

Every particle has its own amplitude.

The mechanism of airfoil in lifting up the air plane. 

Graph plotting of the amplitude with respect to the kinetic and potential energy.

Characteristics of waves: The formula of velocity of waves for transverse waves, where v=velocity, m=mass of string, T= tension in string and l=length of string.

Characteristics of waves: The formula of velocity of waves for longitudinal waves,  where E= elasticity (except for sound), v=velocity and p= density.

"In the musical language, over tones start from f2 ans harmonics start from f1."

"Time period greater in water than in air due to density."

"graph of amplitude verses the frequency showing the large damping, no damping and small damping."

Wavelength 1s sound is approximately 2 and a half feet.
