Go back to your nodal equations in (a). Write them in standard form: Av_1+Bv_2+Cv_3=D, then convert them into a square array (matrix) containing all the coefficients of the voltages and an array with a single column of the right-hand side of the equation.

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?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
