An infinite solid cylindrical conductor of radius centered on the z-axis carries a current . The current is uniformly distributed over its cross section and is directed out of the page ( z direction). A coaxial infinite, thin cylindrical conducting shell of radius carries a current into the page (-z direction). 1. What is the magnitude of the B-field inside the inner cylinder at a radius of from the central axis

Asap time is ! best answer gets compose at least one well-developed paragraph on the following: define the term concurrent powers, and give an example of a concurrent power of government.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.

M1 = 2.8 kg, m2 = 6.72 kg, m3 = 11.2 kg, byas in .is ,is .toof m3 it 0.91 m. (in m/s)
