In addition to cable and satellite broadcasts, television stations still use VHF and UHF bands for digitally broadcasting their signals. Twelve VHF television channels (channels 2 through 13) lie in the range of frequencies between 54.0 MHz and 216 MHz. Each channel is assigned a width of 6.00 MHz, with the two ranges 72.0 – 76.0 MHz and 88.0 – 174 MHz reserved for non-TV purposes. (Channel 2, for example, lies between 54.0 and 60.0 MHz.) (a) Calculate the broadcast...

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.85 x 10 Pa and the pipe radius is 2.80 cm. At the higher point located at y = 2.50 m, the pressure is 1.26 x 105 Pa and the pipe radius is 1.60 cm. (a) Find the speed of flow in the lower section. 3.0625 X Your response is within 10% of the correct value. This may...
