Even when using three-wire connections to a strain gage to reduce the effects of leadwire resistance changes with temperature, a phenomenon called leadwire desensitization can occur. if the magnitude of the leadwire resistance exceeds 0.1% of the nominal gage resistance, significant error can result. assuming a 18-gauge (awg) † platinum leadwire (resistivity 10.6·10-8 ωm) and a standard 120 ω gage, how long can the (individual) leads (in inches) be before there is leadwire desensitization?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
