-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.- Artificial Sunset: Why is the sky blue? Why is the sunset reddish? Design one experiment to simulate both the sunset and blue sky in the lab.
2.- Solar energy: Do some research and provide numbers about how large a solar panel need to be so to provide enough energy to run a computer a day with 8 hours of sun light. Assume a computer needs 100kWh a day.
3.-
Space communication: show your
calculations of how long does it take for an EM signal to travel to and from
the Moon; repeat for Mercury. How can we overcome these limitations for the
future of passenger space travel?
