Q1. For years, marine scientists were mystified by sound waves picked up by underwater microphones in the Pacific Ocean. These so-called T-waves were among the purest sounds in nature. Finally they traced the source to underwater volcanoes whose rising columns of bubbles resonated like organ pipes. What is the wavelength of the typical T-wave whose frequency is 8 Hz?
Q2. A 56.0 resistor is connected in parallel with a 117.0 resistor. This parallel group is connected in series with the 27.0 resistor. The total combination is connected across a 15.0 V battery. What is the current of the 117 resistor? What is the power dissipated of 117 ohm resistor?
