PLS HELP! WILL GIVE BRAINLIEST! DON'T ANSWER IF UR NOT GOING TO ANSWER THE QUESTION! Think about the world around you. Choose a real world example of each of Newton's three laws. Create a poster explaining each law and describing how the example you have chosen illustrates the law. Be sure to include a title and an illustration or picture for each law. You can use a graphics program (like Word, Power Point, Publisher or any other that you know) or paper and poster board. Upload your poster in the box below.

If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance. what is its vertical displacement (in m) after 6 s?

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.
