D. Derrick would like to explore his area. He estimates that his walking speed is 3.4 mph in the difficult terrain he has been given. If Derrick leaves at around 12 pm, and the sun sets at 6:45 pm, how far can he explore and still make it back by sunset? Do not include units in the answer box. Please round leaving two numbers after the decimal.

4. Consider a solid surface to be a two-dimensional lattice with M sites and N atoms are adsorbed on the surface. The energy of an occupied site becomes lower by $\epsilon$. Assume that atoms on the surface do not interact with each other, and also $N \ll M$ so that each site has either 0 or 1 adsorbed atom. (a) If the surface is at temperature T, what is the chemical potential of the adsorbed atoms? (b) Suppose an ideal gas of similar atoms of at temperature T and pressure p. There are n atoms per volume. In the case that the surface is in equilibrium with this ideal gas, find out the ratio N/M.
Question 2: A plane wave is generated underwater and propagates toward the surface at an angle \(\alpha\) as shown in Figure. Assume lossless conditions (distilled water) with relative permittivity of \(\epsilon_r = 81\) and \(\mu = \mu_0\) and its amplitude is 1 V/m. The electric field intensity is in the plane as shown. Calculate: i. The electric and magnetic field intensities in air for an incidence angle \(\alpha = 5^\circ\). ii. The incident instantaneous and time-averaged power densities just below the water surface. iii. The transmitted instantaneous and time-averaged power densities in air immediately above the water's surface.
