Evaluate the electric field (magnitude and direction) at a height h above the center of a lat disk with inner radius a and outer radius b. the disk carries a radially-varying surface charge density, σ (s) = ks

What is created when solids, liquids, an gases mix with one another

In a system, when potential energy decreases, then entropy also decreases. true false

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
