Can BJT or phototransistor be used as a sensor? Explain it with
a circuit diagram. How are you going to make it in reversed logic?
What about photoresistors? Can it be used as a sensor?
How are diodes used in circuits? Please don’t provide an answer
to the question “how does a diode work”. If you write a few
sentences based on “a diode only allows current to flow in one
direction”, you will get no credit for your answer.
1) a. How can a galvanometer be used to determine emf in a
circuit?
b. What two factors determine the direction of the induced
emf?
c. When a bar magnet is thrust into one end of a coil, is the
pole produced at the end of the coil the same as, or opposite to
the pole of the bar magnet? Does the action of these two magnetic
fields tend to oppose the motion of the bar magnet or assist
it?...
a) Describe, in detail, how a genetic cross can be used to
identify the number of genes involved in major changes in body form
between two different organisms.
b) If you found a group of similar species living on nearby
islands, describe in detail a method you could use to determine
their exact evolutionary relationship to each other.
c) Describe, in detail, how a mutation in the intracellular
domain of MC1R could change the coat color in rock pocket from...
What is Economic growth? Explain in detail how education can
determine economic growth. Explain in detail how savings and
investments can determine economic growth.
IN DETAIL
Explain three approaches that can be used in order to improve
ROI.
The balanced scorecard contains four dimensions. Please explain
each dimension and how they link to one another.
Discuss in detail what an outlier is and explain how it can be
a disadvantage of using the High-Low method.
The CEO of Keechen & Moore has heard about some firms using
regression analysis (method of least squares) to estimate costs.
Briefly explain the regression method and discuss its main
advantage relative to the High-Low method.
