What makes electricity? Is it the heat or friction or? doesn't higher voltage reduce resistance? why is it higher if voltage "pushes" the electrons and resistance "stops" the electrons"?

Why is it the same resistance before the first resistance and before the last resistance in the same closed circuit??

If voltage is the speed of electrons passing and you measure the speed, how do you measure current? Because doesn't the length of the conductor like decides how many electrons there are? Because the electrons enters AND leaves the conductor

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.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
