1. The middle C string on a piano has a fundamental frequency of 262 Hz, and the string for the first A above middle C has a fundamental frequency of 440 Hz. a. Calculate the frequencies of the next two harmonics of the C string. If the A and C strings have the same linear mass density µ and length L, determine the ratio of the tensions in the two strings.1.

Problem D. In this exercise you will show that \begin{equation*} \sum_{k=1}^n k^2 = \frac{n(n+1)(2n+1)}{6} \end{equation*} (i) By expanding out the sum, show that \begin{equation*} \sum_{k=1}^n [k^3 - (k - 1)^3] = n^3. \end{equation*} (ii) Compute $k^3 - (k - 1)^3 = 3k^2 - 3k + 1$. (iii) Sum both sides of (ii), and use (i) to prove the desired formula.

The patient says she is here for a Bâ‚â‚‚ injection and the order reads "Cyanocobalamin 500 mcg IM now." You have never given cyanocobalamin or a Bâ‚â‚‚ injection before. What should you do? 2. Using the order in question 1, you find a vial of cyanocobalamin that is 1,000 mcg/mL and give the patient a 1 mL injection in the deltoid muscle of her left arm. When you get ready to chart the medication, you realize you should have given only 0.5 mL of the medication. What should you do now?
