product is testedfor radiated emissions compliance at 150 MHz where the distance between the DUT and the measurement antenna is 16 ft. The measurement antenna provides 0.2 V for every V/m in the incident field and is connected to the spectrum analyzer by 20 ft of coaxial cable (attenuation = 6.2 dB/100 ft at 150 MHz). The voltage measured by the spectrum analyzer is 36 dBμV. Determine the antenna factor in dB.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

If a balloon is taken outside on a very cold day, what will occur?
