What is the magnitude of the electric field at a point a distance ρ = 73 cm from an infinitely long line of a uniform positive charge per unit length ρL = 5 × 10-9 C/m. ke = (1/4πε0) = 9 x 109 N. m2/C2

ε0 = 8.85 x 10-12 C2/N. m2

Asteel wire of 2 mm diameter is fixed between two points located 2 m apart. the tensile force in the wire is 250n, if its density of steel is given by 7830 kg/m3 the fundamental frequency of vibration hz? ?

Air (c-1.006 kj/kg.k, r-0.287 kj/kg.k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
