The dc bias at the gate of transistor m3 is 0 v (ground). notice the polarity of the 100 uf capacitor in the schematic. (the triangle symbol is the same as ground.) is the polarity of the capacitor correct, or is this a mistake that i will point out to you during lab? support your answer with at least one complete sentence.

Ahe-xe mixture containing a 0.75 mole fraction of helium is used for cooling electronics in an avionics application. at a temperature of 300 k and atmospheric pressure, calculate the mass fraction of helium and the mass density, molar concentration and molecular weight of the mixture. if the cooling capacity is 10 l, what is the mass of the coolant?
