1. (10 points) Write out your pre-lab prediction‚ including what evidence or previous knowledge you have to support that prediction. --Answer below: Things "rising" and "setting" give the appearance of something rising or setting. In reality objects like the Sun or Moon aren’t physically rising from the horizon. Most of the motions we see in the sky are caused by the Earth’s motion‚ both its rotation and orbital motion. So all of the "motions" described below are really apparent motions and not

this lab was to a digital oscilloscope to measure various signals. The goal of Part 1 was to measure the mean value‚ the frequency‚ peak to peak voltage‚ and the RMS voltage of a triangular input signal. To meet this goal‚ a function generator was used to generate a 1 kHz triangular wave signal with a 1 V amplitude‚ and the oscilloscope was used to measure the values of that signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage was 292 mV‚ the frequency was 1 kHz

Some common RFC’s are RFC1866 (HTML)‚ RFC894 (Ethernet)‚ and RFC1180 (TCP/IP). RFC’s date back all the way to 1969 when the first RFC was published‚ RCF 1. RFC 1 was about host software and was made while working on the ARPA net. I bring up RFC 1 just as an example of how RFC’s documenting standards over the evolution of technology can be a great tool of keeping record.
