Non-minimum phase systems are defined as those in which the transfer function has a positive zero, i. e., a root of the numerator is greater than zero. with these types of systems, it is notoriously difficult to achieve good feedback control performance. why?

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.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
