A tire that has been run flat has just been removed from an Alcoa aluminum rim. Technician A states to roll the rim on a flat level surface for a minimum distance of 10 feet to ensure that it rolls in a straight line. Technician B states to use a square to ensure that there is no more than .030 gap between the square and the rim flange. Who is correct?

Which fators influence ocean currents

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
