6. A 10-GHz line-of-sight microwave communication link consists of two lossless parabolic dish antennas, each has 40 dB gain. If the receiver antenna requires 3 nW of receive power for good reception and the distance between the antennas is 35 km, how much power (in both mW and dBm) should be transmitted?

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...

Copper is a toxic metal routinely found in older piping systems. Water treatment plants must report to EPA any values of copper ions in their water that exceed 1.3 mg/L, as it is hazardous above this level. Water running through the pipes contains bicarbonate at a fixed concentration of 95 mg/L (reminder: pK_a2 = 10.35 for carbonate system). Assume that copper is present in pipes as copper (II) carbonate [solid], which can disassociate into water per the equation below: CuCO_3(s)...

Fitting a Line to Data The method of least squares is a standard approach to the approximate solution of overdeter- mined systems, i.e., sets of equations in which there are more equations than unknowns. The term "least squares" means that the overall solution minimizes the sum of the squares of the errors made in the results of every single equation. In this worksheet you will derive the general for- mula for the slope and y-intercept of a least squares line....
