For the series circuit, determine the amount of current ery. For the parallel circuit determine the total resistance in the circuit. Current: Resistance: (2) A ship sends a sonar signal (underwater sound wave). The signal travels at 1500 m/s in the water. The signal is sent out and then returns to the ship 0.2 seconds later. How far away is the object that the signal bounced off of? (3) Why does visible light pass through glass but ultra-violet does not?

Answer 1

R. R2 Към R3 gv Ry - 10012, R2 = 300 1 and R3 =502 30 total resistance of the circuit C R total = R , +R₂1 R₂ = 4502 Thus, Amount of current flowing out of the battery is I = = = 0.02 A 450 R total gv = RB R, = 32, R2=32 and R3=32 so total resistance of the circuit is given by Rental 0 Rz 83 _ = or a total = 12 - R, R₂ + R, R₂ + R₂ R3 12
