3. Give a definition of mild, moderate, and severe brain injury, outlining the criteria for determining the difference in severity. Mild brain injuries are referred to as a concussion, and it refers to a relatively minor traumatic brain injury (TBI). It is characterized by temporary disruption of brain function due to a blow to the head, and may include loss of consciousness for a few seconds or minutes.

c) Consider a planar interface between two media. If there are no free charges or currents at the interface, the normal and tangential components of the $\vec{D}$ and $\vec{H}$ fields, $\vec{D}_n$ and $\vec{H}_t$, respectively, are continuous across the interface. Derive equivalent continuity conditions for the field components $\vec{E}_t$ and $\vec{B}_n$. PAGE 3 Continued overleaf. Electromagnetism (PHYS09060) d) Now consider the media that form the interface to be linear isotropic homogeneous (LIH) media characterised by wave impedances $Z_1$. A linear polarised electromag- netic wave approaches the interface at normal incidence as shown below. $Z_1 \mid Z_2$ $\vec{H}$ $\vec{E}$ $\vec{k}$ Use the field continuity conditions to show that the amplitude reflection and trans- mission coefficients are, respectively, $r = \frac{Z_2 - Z_1}{Z_2 + Z_1}, \quad t = \frac{2Z_2}{Z_2 + Z_1}$ In the case both media are non-magnetic dielectrics, rephrase the expressions for $r$ and $t$ in terms of their refractive indices $n_i$. Assume the second medium's magnetic properties can be modified. Express its magnetic permeability $\mu_2$ in terms of $\epsilon_r$ so that the amplitude reflection coefficient will be minimised. $\frac{\partial I}{\partial t} = \alpha \sigma_0 \vec{E}$. Use this e) In a plasma, charges are free to accelerate and currents follow to derive a modified wave equation. Show that in a plasma, electromagnetic plane waves behave as in a medium of relative permittivity $\epsilon_r(\omega) = 1 - \frac{\omega_p^2}{\omega^2}$.

Property taxes 12,000/yr. & Homeowner Insurance 1000/yr 1. You are planning on buying a house in Clifton, New Jersey at an expected price of $ 450,000, with a traditional (meaning 20% down payment, 80% mortgage financed), Fixed Rate, 30 year mortgage at 4.5%/year interest rate. (Each part 10 points each, 3X10-30points) A. Please calculate the monthly payment required to service the above mortgage 4.5\% yr N = 360 month PMT = 1817.25 F B. i. Utilizing the FNMA mortgage qualifying formula as discussed in class, calculate the monthly income required to be approved for the loan. ii. You would like to reduce the length of the mortgage; you are trying to add an additional $ 300.00 per month to pay down the mortgage earlier than 30 years. Please calculate the length of the mortgage under this scenario. How would you discuss rationally whether the trade- off makes sense. Taxes = 12,000 C. Your spouse would like to have a 15 year mortgage. As it so happens, because of the reduced length of the mortgage, the interest on these mortgages are less, 4%/year. The loan amount remains the same. Calculate the monthly payment required.

(i) In a car race, sound signals emitted by the two cars are detected by the detector on the straight track at the endpoint of the race. The observed frequencies are 330 Hz and 360 Hz. The original frequency of the horn is 300 Hz for both cars. The race ends with a separation of 1000 m between the cars. Assume both cars move with a constant velocity and the velocity of sound is 330 m/s. Find the time (in seconds) taken by the winning car to finish the race. (ii) A source of sound with frequency f is dropped from rest from a height h above the ground. An observer O1 is located on the ground, and another observer O2 is inside water at a depth d from the ground. Both O1 and O2 are vertically below the source. The velocity of sound in water is 4V, and the velocity of sound in air is V. Find: (a) The frequency of the sound detected by O1 and O2 corresponding to the sound emitted by the source initially. (b) The frequency detected by both O1 and O2 corresponding to the sound emitted by the source at a height h/2 from the ground.
