Aflute player hears four beats per second when she compares her note to an 880 hz tuning fork (note a). she can match the frequency of the tuning fork by pulling out the "tuning joint" to lengthen her flute slightly. what was her initial frequency?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

When using the scientist method, which step comes last?

What you see with your eyes is a form of energy. a. light b. heat c. chemical d. electrical
