4. The cross section of a parallel wire transmission line and the formulas for its unit-length inductance and capacitance are given below. The permittivity and permeability in free space are given as $$ \epsilon_0 = 8.854 \times 10^{-12}F/m $$ and $$ \mu_0 = 4\pi \times 10^{-7}H/m $$. a) For $$ d/a = 8 $$, what are the values of the unit-length L, C and the characteristic impedance $$ Z_0 $$ of the parallel wire transmission line? (the parallel wires are in free space, $$ \epsilon_r = 1 $$) b)What is the ratio of $$ d/a $$ that makes $$ Z_0 = 50 $$ Ohm? Parallel Metal Wires For $$ d \gg a $$: $$ C = \frac{\pi\epsilon_0}{\ln(\frac{d}{a})} $$ $$ L = \frac{\mu_0}{\pi}\ln(\frac{d}{a}) $$ $$ LC = \mu_0\epsilon_0 $$ Figure 3: Dimension and unit-length L, C parameters of parallel wires.

If a company has a favorable materials price variance but an unfavorable materials quantity variance, this likely indicates that: Lower-quality materials were purchased at a reduced price but more were used than expected Materials were purchased at a higher price than budgeted Higher-quality materials were purchased, resulting in lower usage There was no relationship between price and quantity used

In this problem we wild calculate the antiderivative of $f(x) = \sqrt{1 - x^2}$ on the interval [0,1] starting at point a = 0 -1 0 θ X 1 a. The graph of $f(x)$ on the interval [-1,1] is a semicircle. Use trigonometry to find the angle θ in terms of x. b. Use θ to find the area of the red sector. c. Find the area of the blue triangle in terms of x. d. Use the previous two parts to find the area under the function from 0 to x. x $F(x) = \int_0^x \sqrt{1 - t^2}dt =$ e. The FToC claims that the answer to part d is the antiderivative of $f(x)$. Use differentiation to check this claim. (Hint: take the derivative of $F(x)$ and simplify. Simplifying may take some effort.) f. Do you think the antiderivative $F(x)$ works for negative values of x? Why or why not?

2. Estimate the nuclear spin (total angular momentum) and parity of following nucleus in ground sate:- As(33,75), Ni(28,61), Na(11,23), Mn(25,55), Ne(10,19) (use the concept: when competing nuclear states are very close then the pairs of nucleons go into higher orbital angular momentum states (high l-value) rather than s or p states (Low l value)
