Two fixed points, A and B, are such that A is 4 m vertically above B. A light spring of natural length 1.5m is attached to A, and at the other end it has a particle of mass 6kg attached. A second light spring of natural length 1 m is attached to the point B. Its other end is attached to the same particle. Both springs are in the same vertical plane. Given that the modulus of elasticity of the lower spring is one-third of that of the upper spring, and that the extension of one spring is six times the compression of the other spring, find the modulus of elasticity of the lower spring.

1. [20 points] Counting Duplicate Words Write a script that uses a dictionary to determine and print the number of duplicate words in a sentence. Treat uppercase and lowercase letters the same and assume there is no punctuation in the sentence. Words with counts larger than 1 have duplicates. Use the following sentence to test your code: text = ('this is sample text with several words' 'this is more sample text with some different words') Your output for this sentence should look something like the following: WORD COUNT is 2 sample 2 text 2 this 2 with 2 words 2

You are to determine a precise cost function for the worst-case running time of the function shown below. void bar1(int arr[], int n) { int i = 0; while (i < n - 1) { int j = 0; while (j < n - i - 1) { if (arr[j] > arr[j + 1]) { int temp = arr[j]; arr[j] = arr[j + 1]; arr[j + 1] = temp; } j++; } i++; } } Each statement (a line ending in ;) counts as a single operation regardless of its complexity - this includes cout statements with multiple output. The same rule applies to conditions. Show the algorithm's cost function by entering a number in each of the boxes below. If a term is not applicable for the function you must enter a 0. The number you enter may include a decimal fraction, however if it is a whole number do not append .0 to the number. If the number is negative, precede it with a minus sign with no spaces. For example, if you think the cost function is 2.5n - 5 your solution should be entered as $0n^2 + 2.5n$ + -5.

Due to the integrated nature of their capital markets, investors in both the United States and the U.K. require the same real interest rate, 4% on their lending. There is a consensus in capital markets that the annual inflation rate is likely to be 5% in the United States and 3% in the U.K. for the next three years. The spot exchange rate is currently $1.25/Â£. The Fisher effect holds. What is the forward dollar-pound exchange rate for a two-year maturity? A) $1.3242/Â£ B) $1.2990/Â£ C) $1.1801/Â£ D) $1.2262/Â£ E) $1.2743/Â£
