Using offset-nulling facilities provided for the op amp, a closed-loop amplifier with gain of+1000 is adjusted at 25°c to produce zero output with the input grounded. if the input offset-voltage drift is specified to be 20 μv/°c, what output would you expect at 0°c and at 100°c? while nothing can be said separately about the polarity of the output offset at either 0 or 75°c, what would you expect their relative polarities to be?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
