a. Derive an expression for the magnetic field strength at distance $d$ from the center of a straight wire of finite length $l$ that carries current $I$ b. Determine the field strength at the center of a currentcarrying square loop having sides of length $2 R$. c. Compare your answer to part $b$ to the field at the center of a circular loop of diameter $2 R .$ Do so by computing the ratio $B_{\text {square }} / B_{\text {circle }}$

You have a $1.0-$ m-long copper wire. You want to make an $N$ -turn current loop that generates a 1.0 mT magnetic field at the center when the current is $1.0 \mathrm{A}$. You must use the entire wire. What will be the diameter of your coil?

Parasaurolophus was a dinosaur whose distinguishing feature was a hollow crest on the head. The $1.5-\mathrm{m}$ -long hollow tube in the crest had connections to the nose and throat, leading some investigators to hypothesize that the tube was a resonant chamber for vocalization. If you model the tube as an open-closed system, what are the first three resonant frequencies?

A brand of corn flakes come in a box that says it holds 16 ounces of cereal. The manufacturer says that the weights of corn flakes have a normal distribution with a standard deviation of .2 ounces. If the manufacturer ships 810,000 boxes then how many boxes weigh less than 15.92, more than 15.92, less than 16.52, more than 16.52…"
