Logic gates are being discussed. Technician A says NOT gate operation is similar to that of two switches in series to a load.
Technician B says an AND gate simply reverses binary is to os and vice versa.
Who is correct?
a. A only
O b. B only
Oc. Both A and B
O d. Neither A nor B

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

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.
