The feedback transconductance amplifier in Fig. Pl 1.53 uses a differential amplifier with a voltage gain //, an input resistance Rid = 100 kQ, and an output resistance rol = 1 kQ; and a MOSFET with gm = 2 mA/V and ro2 = 20 kQ. (a) Find the value of R2 that results in the closed-loop gain Io/Vs having an ideal value of 100 mA/V

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
