(II) A mass m on a frictionless surface is attached to a spring with spring constant k as shown in Fig. 14-47. This mass-spring system is then observed to execute
(a) Starting with Eq. 14–7b, show why a graph of T2 vs. m is expected to yield a straight line. How can k be determined from the straight line’s slope? What is the line’s y-intercept expected to be? (b) Using the data in the Table, plot T2 vs. m and show that this graph yields a straight line. Determine the slope and (nonzero) y-intercept. (c) Show that a nonzero y-intercept can be expected in our plot theoretically if, rather than simply using m for the mass in Eq. 14-7b, we use m + m0, where m0 is a constant. That is, repeat part (a) using m + m0 for the mass in Eq. 14-7b.Then use the result of this analysis to determine k and m0 from your graph’s slope and y-intercept. (d) Offer a physical interpretation for m0, a mass that appears to be oscillating in addition to the attached mass m.

- Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.

A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced.
