Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. What is the voltage across an 8.50 nmthick membrane if the electric field strength across it is 5.75 MV/m? You may assume a uniform electric field.

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.
