A coaxial cable has an inner conductor radius 1𝑚𝑚 and an outer conductor radius 5𝑚𝑚. The dielectric material between the conductors has a relative permittivity 𝜀 = 3 × 10−11, permeability 𝜇 = 4𝜋 × 10−7 and conductivity 𝜎 = 0. The conductors are made of silver. Calculate the transmission line parameters at 500𝑀𝐻𝑧 frequency.

The inflation rate in the US was 2.3%, and in Korea, 6.7%. The won (KRW) went from 1,200 to 1,240 KRWs (one thousand...)/ USD. What would be the real value of the won measured in USDs ($US as the local or quoted currency)? How much would the won change in real terms (measured in USDs)? How do you interpret the results?

Valuing preferred stock Aa Aa Companies that have preferred stock outstanding promise to pay a stated dividend for an infinite period. Preferred stock is treated like a perpetuity if the payments last forever. Preferred stocks are considered to be a hybrid of a stock and a bond. For example, one of the major differences between preferred shares and bonds is that the issuing companies can suspend the payment of their preferred dividends without throwing the company into bankruptcy. However, similar to bonds, preferred stockholders receive a fixed payment-their dividend-before the company's residual earnings are paid out to its common stockholders and, as with common stock, preferred stockholders can benefit from an appreciation in the value of the firm's stock securities. Consider the following case of National Petroleum Refiners Corporation (NPR): National Petroleum Refiners Corporation (NPR) pays an annual dividend rate of 11.20% on its preferred stock that currently returns 15.01% and has a par value of $100.00 per share. What is the value of NPR's preferred stock? $74.62 per share $100.00 per share $111.93 per share $89.54 per share Suppose that due to high inflation, interest rates rise and pull the preferred stock's yield to 19.51%. The value of the preferred stock will

012 10.0 points A sample of an ideal gas is in a tank of constant volume. The sample absorbs heat energy so that its temperature changes from 367 K to 1101 K. If $v_1$ is the average speed of the gas molecules before the absorption of heat and $v_2$ their average speed after the absorption of heat, what is the ratio $\frac{v_2}{v_1}$? 1. $\frac{v_2}{v_1} = 3$ 2. $\frac{v_2}{v_1} = 1$ 3. $\frac{v_2}{v_1} = \frac{1}{3}$ 4. $\frac{v_2}{v_1} = \sqrt{3}$ 5. $\frac{v_2}{v_1} = 9$ 013 10.0 points
