The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

Suppose that an electromagnetic wave which is linearly polarized along the xβaxis is propagating in vacuum along the zβaxis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity Ο, magnetic permeability Β΅ and electric permittivity Ξ΅. (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 ^β1 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.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0mΓ9.0mΓ2.4m . if the outdoor temperature is 30 βc and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 βc is 31.8 torr.
