-Only
members with their names on this cover sheet will receive credits.
-Collaborations
between team members are encouraged; however one or two authors will be
responsible for one problem and may be asked to explain it.
-The
authors should present the solution on a blank sheet with their names on it. Submissions from a same team should be
stapled together
-Solutions
should include “self-explained” diagrams/sketches, with minimal wording. Neat
presentation will count toward the problem grading.
1.- Capacitors: explain what are the priorities: more charges or more energy stored in batteries used to propel cars or even light planes. What are the current limitations, and what do you think can be done in the future?
2.- Circuits:
is there any similarity between electrical current and water flow?
Is it possible to draw an equivalent circuit for the circulatory system in our body, can you draw
one with as much details as you can?
3.-
Magnetic force: describe in
technical details how magnetic levitation works. Give an estimate of the field
strength in Tesla using the equations on how large a magnetic field and or
current are needed to levitate a train such as that in Disney World
