Suppose you are an engineer, and you are asked to measure the force on a supporting beam of a bridge. You measure it to be 50,067 lbs, but you know that your scale is only precise to ±400 lbs. How do you record this measurement in your final report to the client? (Keep in mind that you want to find the perfect way to express the number to give an idea of how precise it is.) Click the above link to submit a three sentence description, which includes:

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

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.
