g Consider two parallel wires placed a distance of (12.5 A) cm apart. The current in the first wire is (4.50 B) A and the current in the second wire is (1.25 C) A. Determine the magnitude of the force per length exerted by the first wire on the second wire. Calculate the answer in Newtons per meter (N/m) and rounded to three significant figures.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
