What value of inductance should be used in a series circuit with a capacitor of 9.0  10-4 mF when designed to radiate a wavelength of 70 m? (c = 3.00  108 m/s)
 a. 3.8  10-4 mH
  c. 3.8 mH
  b. 1.9  10-4 mH
  d. 1.5  10-3 mH

Question 2

The Doppler shift of ultrasonic waves can measure the speed of blood in an artery. If the frequency of the stationary source is 100 kHz and the reflected sound has a Doppler shift of 300 Hz, what is the blood flow speed? (The speed of sound inside the body is 1500 m/s.)
 a. 1.0 m/s
  c. 2.2 m/s
  b. 1.5 m/s
  d. 3.3 m/s
