Isaac just moved to a new state for his job. He doesn’t yet know anyone there or in his new company. However, Isaac is really excited about his job and his previous work and educational background mean that he has the needed skills and knowledge to really excel at it. Which of the following is TRUE for Isaac?

A conductor of radius r, length L and resistivity p, has resistance R.  It is melted down and formed into a new conductor, also cylindrical, with one third the legnth of the original conductor.  The resistance of the new conductor is

5. d) The transmit power of a satellite is 20 W. The gain of the transmit antenna is 30dB while the gain of the receive antenna is 20dB. Distance from the satellite to the ground receiver antenna is approximately 1000 km. The operating frequency is 9 GHz.  Recalling the following “Friis” relationship governing received  and transmitted power between 2 antennas separated by a distance R (Hint: you don’t want to use dB or dBm values for any quantities in this equation. )  Choose from the following options the one that best fits the power level in dBm received at  the output of the ground antenna  

  Assume you are testing a mixer using the test configuration above. And that you have measured the spectral response at the output of the mixer and have corrected  for the IF output cable and pad at all frequencies.  Now you want to compare your data to what may be expected from manufacturer data sheet information for the mixer.     The mixer’s data sheet information includes the intermodulation table below, and that you setup the RF and LO  frequencies as indicated below the table as test conditions and adjust the power levels for each such that they are -14 dBm @2850.1 MHz  and +7dBm @2880.1 MHz at the RF and LO ports, respectively.   Note in the intermodulation table below all values are in -dBc (values below the carrier) except where indicated with a “+” sign. For each question, pick the closest answer to what you come up with.
