Two protons are aimed directly toward each other by a cyclotron accelerator with speeds of 2.70×105 m/s , measured relative to the earth. Find the maximum electrical force that these protons will exert on each other. Please answer as soon as possible!! Thank you

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.

In a system, when potential energy decreases, then entropy also decreases. true false
