The voltage-current relationship for the circuit shown in Fig P1.17 is given by Ohm’s law as V=I R, where V is the current in amps, and R is the resistance of the resistor in ohms. (a) Sketch the graph of I as a function of V if the resistance is 5 ohms.
(b) Find the current I if the applied voltage is 10 V.

Ajet plane has a sound level of 120 db at a distance of 60 m. what is the q23. sound level at a distance of 6.0 km? (60)2 (6000)? om solution 80db db, hint: 16x assume ultrasound waves travel through the body of an animal at 1540 q24. m/s. if a 30,000 hz signal were reflected off a portion of a heart which was moving toward the source at 3 m/s, what frequency signal would return to the stationary source? solution 30.117hz
