Block 1, of mass m1 = 3.90 kg , moves along a frictionless air track with speed v1 = 31.0 m/s . it collides with block 2, of mass m2 = 51.0 kg , which was initially at rest. the blocks stick together after the collision. what is the change δk=kfinalâkinitial in the two-block system's kinetic energy due to the collision?

Suppose that an electromagnetic wave which is linearly polarized along the xâaxis is propagating in vacuum along the zâaxis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity Ď, magnetic permeability Âľ and electric permittivity Îľ. (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 ^â1 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.

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
