a.) What procedures could you use to calibrate a sensor that is
only required to provide approximate measurements of liquid
level?
b.) What is the principal advantage of an optical sensor?
Discuss the mode of operation of the two main types of optical

You are given the following components in a Light Sensor
Circuit:
Light Dependent Resistor (LDR)
Bright condition (500 lux)
Dark Condition (50 lux)
Resistance values (reference)
1 kΩ
5 kΩ
Light Emitting Diode (LED)
Turn on Voltage Rating
Turn on Current Rating
Characteristics (White)
4.0 V
20 mA
Your goal is to design a light sensor circuit which
turns on the LED when it is in a dark room, and turn off
the LED when the room is lit. The...
How could you use play in light of Vygotsky’s
sociocultural theory? How could you use play in light of Piaget’s
four stages of cognitive development theory?
Discuss, using an example from an organization you are familiar
with, how a company could use a variable costing system, as well as
an absorption costing system. You have the option of using the
company you work for as an example. Explain which method is better
for the company being discussed?
How could you dissociate a diatomic molecule, at equilibrium,
without changing the temperature of the system? [Suggested key
words: equilibrium constant, concentration, ratio,
volume...]
This is a P-Chem problem
