Question

If 0 < θ2 < θ1 < π/4, cos(θ1 + θ2) = 3/5, cos (θ1 - θ2) = 4/5, then sin2(θ1) equal to

Answer 1

Answer:

Magnetic susceptibility is the degree to which a material can be magnetized in an external magnetic field. If the ratio between the induced magnetization and the inducing field is expressed per unit volume, volume susceptibility (k) is defined as.
