Q. A 63 resistor is connected in parallel with a 115 resistor. This parallel group is connected in series with a 19 resistor. The total combination is connected across a 15 V battery.

Find the current in the 115 resistor.

Q. In one of the original Doppler experiments, one tuba was played on a moving platform car at a frequency of 75 Hz, and a second identical one was played on the same tone while at rest in the railway station. What beat frequency was heard if the train approached the station at a speed of 18 m/s?
