In the circuit below, find fCO and VO if Vin = 42 V, R = 22 K, and C = 0.00015 æF.
a. VO = 29.7 V, fCO = 48.2 KHz
b. VO = 21.0 V, fCO = 48.2 KHz
c. VO = 21.0 V, fCO = 31.7 KHz
d. VO = 29.7 V, fCO = 31.7 KHz
e. VO = 21.0 V, fCO = 34.1 KHz
Provide an appropriate response.Suppose you have to develop a model to predict snowfall for the upcoming winter based on data from previous winters. Consider the table of annual snowfall over the last five years:
Would it be possible to come up with one model that predicted very low amounts of snowfall and another that predicted very high amounts of snowfall? How so? If you were employed by a ski resort to come up with a model, what type of model would you use? What could be done to try to reduce the chance of coming up with such different models?
