If the value of the feedback resistor in the filter is changed but the value of the resistor in the forward path is unchanged, what characteristic of the filter is changed?

Two finned surfaces with long fins are identical, except that the convection heat transfer coefficient for the first finned surface is twice that of the second one.

A convergentâdivergent nozzle has an exit area to throat area ratio of 4. It is supplied with air from a large reservoir in which the pressure is kept at 500 kPa and it discharges into another large reservoir in which the pressure is kept at 10 kPa.

Five kg of water is contained in a piston-cylinder assembly, initially at 5 bar and 300°C. The water is slowly heated at constant pressure to a final state.

Write multiple if statements: If carYear is before 1968, print "Probably has few safety features." (without quotes). If after 1971, print "Probably has head rests.". If after 1991, print "Probably has anti-lock brakes.".

An incompressible fluid flows along a 0.20-m-diameter pipe with a uniform velocity of 3 m/s. If the pressure drop between the upstream and downstream sections of the pipe is 20 kPa, determine the power transferred to the fluid due to fluid normal

Assign courseStudent's name with Smith, age with 20, and ID with 9999. Use the printAll () member method and a separate println () statement to output courseStudents's data. Sample output from the given program: Name: Smith, Age: 20, ID: 9999

Which renewable sources are growing at the fastest rate? Which renewable source is used to produce most electricity?

Air is compressed in the compressor of a turbojet engine. Air enters the compressor at 270 K and 58 kPa and exits the compressor at 465 K and 350 kPa. Take the average specific heat at constant pressure (cp, avg) of air as 1.015 kJ / kg.

A digital-to-analog converter uses a reference voltage of 120 V dc and has eight binary digit precision. In one of the sampling instants, the data contained in the binary register = 01010101.

What is a perpetual motion machine of the second kind?
