If `mu` is the universal set and P is a subset of `mu` then what is `Pnn(P-mu)uu(mu-P)` equal to

If P and Q are subsets of mu , then P - Q =

If mu is the permeability and epsilon is the permittivity then (1)/(sqrt(mu epsilon)) is equal to

If mu is the permeability and in is the permittivity then (1)/(sqrt(mu in)) is equal to

If mu is the permeability and in is the permittivity then (1)/(sqrt(mu in)) is equal to

If mu is the mean of a distribution , then sumf_i(y_i-mu) is equal to

The quantities P and Q are related by P/Q = mu where mu is the linear mass density and Q is specific latent heat. Then dimension of P will be same as

An achromatic prism is made by combining two prisms P_(1)(mu_(v)=1.523,mu_(r)=1.515) and P_(2)(mu_(v)=1.666,mu_(r)=1.650) Where mu represents the refractive index if the angle of the prism P_(1) is 10^(@) then the angle of the prism P will be
