A voltage of 20 u(t) V, where u(t) is the unit step function, is applied to a circuit consisting of the series combination of a 100 KΩ resistor and a 0.01 µF Capacitor.

a. What is the time constant of the series RC circuit?
b. What will be the values of the voltage across the capacitor and the current through the resistor at 0.5 msec?
c. At what time will the voltage across the resistor be 1.5 V?
d. At what time will the voltage across the capacitor be 8 V?

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
