Aboard the shuttle for this flight was the first teacher in space. Should civilians be allowed on what is basically an experimental launch vehicle? At the time, many felt that the placement of a teacher on the shuttle was for purely political purposes. President Reagan was thought by many to be doing nothing while the American educational system decayed. Cynics felt that the teacher-in-space idea was cooked up as a method of diverting attention from this problem and was to be seen as Reagan doing something for education while he really wasn't doing anything. What are the ethical implications if this scenario is true?
Treat as an ideal gas ie it obeys pV=nRT law where pis pressure, V is volume, n is # of moles, R=82.056*10-6 m3-atm/mole-K is the universal gas constant and T is the absolute temperature.
Calculate the Thevenin equivalent voltage (in Volt) for a power source with the following characteristics: open circuit voltage Voc = 12 V and sort circuit current Isc = 5 mA.
Discuss how you could build a microwave power amplifier with a power rating of 1kW with microwave power transistors with an upper power limit of 100W each. Explain how the speed of an aircraft can be measured by using pulse radar techniques.
A serial input finite state machine has one input and one output. The output becomes 1 and remains 1 thereafter when at least two 0's and at least two 1's have occurred as inputs, regardless of the order of occurrence. Draw a state diagram for the..
imagine you are advising a company that owns a large database and has customers distributed across the usa. the
A 30kw, 300v d.c. shunt generator has armature and field resistances of 0.05 ohm and 100 ohm respectively. - Calculate the total power developed by the armature when it delevers full load output.
A balanced wye-connected load of (4 + j3) Ω is connected across a three-phase source of 173 V (line-to-line).
Show a diagram of how a FET can be biased? Explain how to calculate the DC parameters, such as, Id (Id = Is), Vgs and Vds.
Assuming zero initial conditions. a. Obtain the expression for the time constant of the system
Design a Common Emitter amplifier with no bypass capacitor to obtain a voltage gain of -10 when Rin= 2k, Rload= 4k, VCC= 15V, VBE= 0.6V, and beta= 300. This amplifier requires an output swing of 4V peak-to-peak.
