- The direction of the induced emf in the coil as current increases from 0 up to 10A over 0.1 seconds is?r=7.8cm N=50 Questions: Part 1: t=15s ; Find B=? Part 2: L=1m E=17v B=? (use B from part 1) Find: v=? (Velocity)A length of string is attached to a speaker and passed over a pulley, as shown in the figure. A mass is attached to the hanging end of the string. The distance between the speaker and the pulley is L = 0.767 m. The entire length of the string is 1.11 m and the mass of the string is measured to be 0.396×10-3 kg. The speaker is connected to a function generator that is set to produce a sinusoidal waveform having frequency 53.5 Hz. This causes the string to oscillate in the third harmonic. 1. Determine the wavelength, in meters, of the standing transverse wave in the string for the third harmonic. 2. What is the propagation speed, in meters per second, of a transverse wave in the string? 3. What is the tension in the string, in newtons? 4. What is the mass, in kilograms, of the object hanging from the end of the string?
