What is the number nn of the highest harmonic that could be heard by a person who is capable of hearing frequencies up to ff = 16 kHz? f1=319 Express your answer exactly. View Available Hint(s)for Part B Hint 1for Part B. Harmonics of a string The harmonics of a string are given by fn=nf1fn=nf1, where fnfn is the nn th harmonic of a string with fundamental frequency f1f1. Be careful if you get a noninteger answer for nn, as harmonics can only be integer multiples of the fundamental frequency. Activate to select the appropriates template from the following choices.

Question C-2: Why is the force on the coil always in the same direction when you feed AC power to a universal motor? Question 7 options: 1) The current flowing through the electromagnet causes the magnetic field to always point North 2) None of these choices are correct 3) The current flowing through the electromagnet and the current flowing through the coil both reverse direction in synch 4) Feeding AC power concentrates the magnetic field of the motor

The RC network in Figure 1.104 has been at rest for a long period of time with the switch S1 opened. At time $t = 0$, S1 is closed as indicated on the schematic. Using the values shown, you are asked to do the following. (a) Calculate values for the voltage $v_1(t)$ at $t = 0^+$ and $t = \infty$ (i.e., $v_1(0^+)$ and $v_1(\infty)$), and the network time constant $\tau$ in seconds. (b) Apply these values to generate and write fully the complete time-domain expression for $v_1(t)$ found from the solution of the network describing equation. (c) Calculate the value for the rise time $t_r$ in seconds.
