- Scr0360: logical operators in
Summary
I provided an explanation of logical operators and truth tables. Then I
presented and explained a Scratch program that illustrates the use of thelogical
and ,
or , and
not operators when used in conjunction
with relational operators.
Finally, I provided the specifications for two student-programming projects
for you to demonstrate your understanding of what you learned from the firstprogram and from earlier modules. One of the student-programming projects is
relatively difficult requiring an understanding of DeMorgan's theorem
(see
Resources ) .
Copies of all three programs have been posted online for your review
(see
Resources for the URL) . If you
don't find the program using that URL, search the Scratch site for the usernamed dbal.
What's next?
Future modules using the Scratch programming language will continue to deal
with
selection and will also deal with
loops .

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
