Use OF Equations

Can we use the equation v = u + at in SHM or not ?

Derive an expression for the van der Waals equation. Give the significance of the constants used in equation.

The rotational K.E. of a body is given by (1)/(2) I omega^2. Use this equation to obtain the dimensions of I.

Checking the correctness of equations using the method of dimensions is based on

Can we use equations of kinematics to find the height attained by a body projected upwares with any velocity ?

One method for calculating Z_(eff) is to use the equation: Z_(eff) = sqrt(((E)(n^(2)))/(1312kJ//"mole")) where E is the energy necessary to remove an electron from an atom and n is the principal quantum number of the electron. Use this equation to calculare Z_(eff) value for the highest energetic electron in potassium. E = 418.8 kJ//"mole"

A beam of natural light falls on the surface of glass at an angle of 45^(@) . Using the Fresnel equations, find the degree of polarization of (a) reflected light, (b) refracted light.

Obtain the sum of the first 56 terms of an A.P. Whose 18th and 39th terms are 52 and 148 respectively. (1) Usint t_(18) and t_(39) find two simultaneous equations in variables a and d. (2) Using these equations, find S_(56)
