5. License Exam Questions of the week

One question is drawn from each of the three question pools. Steve, AE8AT,
is providing these questions.  Thanks Steve

 

Answers are at the end of this email.

 

We received a question regarding the strange mix of letters and numbers that
begin each question.  Every exam question has a unique combination of
letter-number-letter-number.  The first letter is a T, G, or E to identify
the question pool: Technician, General, or Extra.  Next is a single number
representing the category, for example, category zero is safety in all three
exam pools.  The first letter-number pair is called the "sub-element".   The
second letter is a "group" containing related questions.  Example,
sub-element G8 is Signals and Emissions, with group C of that sub-element
being Digital Emission Modes.  The questions are numbered sequentially:
G8C01, G8C02, and so forth always with a 2-digit number at the end.  The
question identity is included in case of a typo or some "help" from
autocorrect obscures either the question or the answer.  

 

Hans Christian Oersted, born 14 August 1777 in Rudkobing, Denmark.  The quiz
this week is how to pronounce Rudkobing.no, the quiz will draw inspiration
from professor Oersted's work, as is our usual.  He is credited with
discovering that electric currents create magnetic fields, and aluminum.  A
perhaps lesser known contribution was the founding the Society for
Dissemination of Natural Science, dedicated to making science accessible to
the general public.  His famous experiment was one where he connected a
battery and observed that a compass needle deflected during a lecture.  For
this discovery, the British Royal Society awarded the Copley Medal in 1820.
