Find the equivalent impedance Zeq seen by the source when Vs = 2 cos (3t) v, C = 2 F, R = 1 Ω and L = 0.1 H. (Give angles in degrees and round final answers to two decimal places.) Calculate the voltage across the inductor. (Give angles in degrees and round final answers to two decimal places.)

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
