Intensity and energy density

A sonic source, located in a uniform medium, emits waves of frequency n . If intensity, energy density (energy per unit volume of the medium) and maximum speed of oscillations of medium particle are, respectively, I , E and u_0 at a point, then which of the following graphs are correct?

What is the unit of energy density for a parallel plate capacitor?

The ratio of intensity of wave and energy density gives

Self Energy and Energy Density

Find the dimensions of energy density.

The intensity of energy radiated by a hot body at distance r from it varies as .

Which of the following is true for elastic potential energy density

Assertion : Pressure has the dimensions of energy density. Reason : Energy density = ("energy")/("volume")=(["ML"^(2)"T"^(-2)])/(["L"^(3)]) =["ML"^(-1)"T"^(-2)]="pressure"

If E is the electric field intensity of an electrostatic field, then the electrostatic energy density is proportional to

Compare the expression for magnetic energy density with electrostatic energy density stored in the space between the plates of a parallel plate capacitor.
