Study the ladder logic program in Figure 7-41 and answer the
questions that follow:
a. What type of timer has been programmed?
b. What is the length of the time-delay
period?
c. What is the value of the accumulated time
when power is first applied?
d. When does the timer start timing?
e. When does the timer stop timing and reset
itself?
f. When input LS1 is first closed, which rungs
are true and...

What physical device in the bathroom resembles the liquid level
switch? 12. Draw logic for a motor starter control circuit for a
motor that is either off, on forward or on reverse with a selector
switch.
You'll implement a completely generic version of an algorithm to
find the maximum of an array. Unlike in the past, when our
algorithm only worked for int[] or double[], this version will work
on any Java objects that are comparable, specifically any Java
object that implements the Comparable interface. Create a public
class named Max with a single class method named max. max should
accept an array of Objects that implement Comparable and return the
maximum. If the array is...
Logic & Sets (Proofs question)
Show that complex numbers cannot be ordered in a way that
satisfies our axioms.
Axioms for order:
1. if x is less than/equal to y and w is greater than zero, then
wx is less than/equal to wy
2. for w, x, y, z w is less than/equal to x, y is less
than/equal to z then w + y = x + z if and only iff w = x and y =
z
The generic metal A forms an insoluble salt AB(s) and a complex
AC5(aq). The equilibrium concentrations in a solution of AC5 were
found to be [A] = 0.100 M, [C] = 0.0340 M, and [AC5] = 0.100 M.
Determine the formation constant, Kf, of AC5. The solubility of
AB(s) in a 1.000-M solution of C(aq) is found to be 0.163 M. What
is the Ksp of AB?
What form of logic is trying to be used in the logic of the 3
propositions below and why does the logic in the last proposition
fail?

·All duck lays eggs
·Therefore, a Platypus is a duck

4. Using non-generic techniques, implement a static method
getMax() that takes an array of type Comparable and returns the
maximum element in the array.
(i.e. "public static Comparable getMax(Comparable []
anArray)").
5. Using the generic techniques to specify super-class
relationships, implement a type safe version of the method in 4
named getMaxGen().
