An oscillator has an equation x(t) = (0.45 m) cos ( 359 t)
Assuming ω is in SI units, calculate the frequency in Hz to 2 sf.
Homework Answers
x(t) = (0.45 m) cos ( 359 t)
compare it with
x(t) =A*cos(ω*t)
so ω = 359 rad/s
ω = 2*pi*f
f = ω /2pi = 359/(2*pi) =57.1366246 Hz
the frequency = 57 Hz answer

Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 711 Hz to 1124 Hz. A point P is located 5.1 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which destructive interference occurs at point P, in SI units, is closest to: Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator,...
