The moment of inertia of a uniform rod about an axis through its center is M L 2 / 12. The moment of inertia about an axis at one end is M L 2 / 3. Explain why the moment of inertia is larger about the end than about the center.

An electromagnetic wave with frequency 65.0 hz travels in aninsulating magnetic material that has dielectric constant 3.64 andrelative permeability 5.18 at this frequency. the electric fieldhas amplitude 7.20 \times 10^{ - 3} {\rm v}/{\rm m}. a. what is the speed of propagation of the wave? b.what is the wavelength of the wave? c.what is the amplitude of the magnetic field? d.what is the intensity of the wave?
