LG5 P10.15 Red Electrica España SA (E.REE) is refinancing its bank loans by issuing Eurobonds to investors. You are considering buying $8,000 worth of these bonds, which will yield 7%. You are also looking at a U.S. bond with similar risk that will yield 4%. You expect that interest rates will not change over the course of the next year, after which time you will sell the bonds you purchase now. a. How much will you make on each bond if you buy it, hold it for one year, and then sell it for $8,000 (or the Eurodollar equivalent)? b. Assume the dollar/euro exchange rate goes from 1.3 to 1.0. How much will this currency changes affect the proceeds from the Eurobond? (Assume you receive annual interest at the same time you sell the Eurobond.)

想請問各位大神，這題為什麼是D🙇🏻‍♀️ （ratio:比例；collision:碰撞）

9-10. You have two samples of the same gas in the same size container, with the same pressure. The gas in the first container has a kelvin ternperature four times that of the gas in the other container, 4T 1 to T 10. The ratio of number of collisions with the wall in the first container compared to that in the second is (a) 1:1, (b) 4:1, ()1:4,(d) 2:1, (e) 1:2. 273

有人知道圈起來的地方的意思是 AgI質量乘 142/233＝新生成的AgCl質量嗎？ 所以這一串式子是原本的AgCl質量再加上後面進行反應新生成的AgCl質量嗎？

4-17. A 0.6407-g sample containing chloride and io- dide ions gave a silver halide precipitate weigh- ing 0.4430 g. This precipitate was then strongly heated in a stream of Cl2 gas to convert the Agi to AgCl; on completion of this treatment, the precipitate weighed 0.3181 g. Calculate the per- centage of chloride and iodide in the sample.

7. 子瑜、娜蓮、定妍、志孝、多姆、采瑛、Mond、Sama、Nina 九個人一同出遊,要從甲地移動到 9 河岸另一邊的乙地。她們可以選擇坐船(有兩艘船可選,A船最多可載6人,B船最多可载5人), 也可以選擇走C橋過河(橋的乘載容量大於9人)。目前已知Mono 跟 Sama 會暈船所以直接選擇走 o 1 C橋過河,而 Nina 因為懼高所以只能搭船,試問在上述條件之下,九人安全移動的方式共有 種。 ALT

有人會解這個嗎？想知道答案

5. (Ch. 14 - Problem 81 in Wolfson) Two loudspeakers are mounted 2.85 m apart, pointing in the same direction and producing identical sound waves of a fixed fre- quency. You're standing 10.0 m from the speakers, on the perpendicular bisector of the line between them. You move in direction parallel to the line between the speak- ers and find that the sound intensity diminishes, reaching a minimum when you've moved 2.44 m. If the sound speed is 343 m/s, what is the frequency of the sound waves?
