Design a small-signal voltage amplifier that meets the following specifications: 1) voltage gain of 50 or more 2) minimum input resistance of 15 kω 3) output resistance less than 100 ω 4) maximum unclipped output of 2v peak-to-peak 5) power supply voltage of 9 v and lower current drain from supply voltage

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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.
