There are four oscilloscopes, A, B, C, and D, in a laboratory that are equipped with individual indicator circuits. These indicator circuits give out a logic 1 anytime the scope malfunctions. Design a circuit that would be able to indicate that three or more of the scopes are malfunctioning.

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.
