I need help with this asap You went to coconino national forest at flagstaff for a five day/s camping trip. you started from base camp. the first day, you hiked 25 km in a direction 60 degrees north of east; second day hiked 31 km 39 degrees north of west; third day, hiked 29 km 21 degrees south of east; fourth day, hiked 18 km 45 degrees south of west; and on the fifth day, you hiked 48 degrees north of west. what is the resultant displacement from the base camp?
(use component's method. figure out the direction and magnitude of the resultant displacement vector)

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

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.
