A long coaxial cable consists of an inner conductor r1 = 1.1 mm and outer conductor with inner radius r2 = 4.2 mm. Charges of +2.3 μC and –2.3 μC are placed on the inner and outer conductors, respectively. Required:
a. If the resulting potential difference between the two conductors is 760 V, what is the capacitance in nanofarads of the cable?
b. What is the length in meters, of the cable?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
