Answer #1

1) When one applies the Kirchhoff loop rule to a circuit, there
is always a electric potential increase across a battery no matter
through which direction one walks through it. T/F
2) If there are 6 meshes in a circuit, then 6 loop equations are
needed to solve for currents in the circuit. T/F
3)
If there are 5 junction points in a circuit, then 5 junction rule
equations are needed to solve for electric currents in the circuit.
T/F...

sustaining treatments and then allowing the person to die naturally
is called: Select one: a. voluntary b. nonvoluntary c. active d.

One of the disadvantage of negative feedback loop is lag
caused because it can only be exerted after controlled variable has
been disturbed. In order to minimize lag between a change in a
controlled variable and the action of the effector, it is
advantageous for the body to anticipate any likely change. Which
one of the following physiological mechanism achieves
this?
Select one:
a. Feedbackward control
b. Feedforward control
c. Positive feedback control
d. All of the above
e. None...

1a.) Stratified Random Sampling involves:
a. Dividing the population into overlapping groups
b. Taking a random sampling of a percentage of the pre-chosen
groups (usually 10% of total groups)
c. Choosing non-overlapping clusters (i.e. streets of a city)
and collecting data from all members of the selected cluster
d. None of the above
1b.) A data set consists of the values 2, 6, 3, and 1. If we
consider this a population (all the values available), the variance
is
a....
