A bank reports the following information relating to its marketable securities classified as available-for-sale securities for a recent year (amounts in millions of US$):$

$$\begin{array}{lcccc} \hline &\underline{\textbf{December 31}}\\ &\textbf{2014}\quad\textbf{2013}\\ \hline \text{Marketable Securities at Acquisition Cost}&\$13,968&\$14,075\\ \text{Gross Unrealized Gains}&1,445&957\\ \text{Gross Unrealized Losses}&\underline{(218)}&\underline{(510)}\\ \text{Marketable Securities at Fair Value}&\underline{\underline{\$15,195}}&\underline{\underline{\$14,522}}\\ \hline \end{array}$$

$Cash proceeds from sales and maturities of marketable securities totaled$37,600 million in 2014. Gross realized gains totaled $443 million, and gross realized losses totaled$113 million during 2014. The carrying value of marketable securities sold or matured totaled $37,008 million. Interest and dividend revenue during 2014 totaled$1,081 million.

Use a graphing calculator to answer each question. Stock A starts out with $900 and gains$50 each month. Stock B starts out with $900 and gains 2% each month . When will Stock B be worth more money than Stock A?

Describe oxidation-reduction reactions by completing the following statements. Many _____ compounds can be converted to other compounds by _____ and ______ reactions. ________ is the loss of _____. A substance is oxidized when it gains _____ or loses _____. Reduction is the _____ of electrons. A substance is reduced when it loses ____ or gains _____.

Why is it that when something gains electrons, it is said to be reduced? What is being reduced?

An electron $e ^ { - }$ and positron $e ^ { + }$ moving at the same speed in the Earth reference frame collide head-on and produce a proton p and an antiproton $\overline { \mathrm { p } }$. The electron and positron have the same mass. The proton and antiproton also have the same mass. The mass of the proton is 1836.15 times the mass of the electron. Calculate, in the Earth reference frame, the minimum value possible for the ratio of the electron’s kinetic energy to its internal energy in order to have the reaction $e ^ { - } + e ^ { + } \rightarrow p + \overline { p }$ take place.

A friend speeds by you in her spacecraft at a speed of $0.720 \mathrm{c}$. It is measured in your frame to be $4.80 \mathrm{~m}$ long and $1.35 \mathrm{~m}$ high. What will be its length and height at rest?
