Chapter 7, Problem 102TDI
You are not harmed by contact with a charged Van de Graaff generator, even though its voltage may be very high. Is the reason for this similar to the reason you are not harmed by the sparks from a fireworks sparkler, even though the temperature of each of those sparks is higher than

Take a square configuration of point charges, two positive and two negative, all of the same magnitude, with like charges sharing diagonals. What will happen to the internal energy of this system if the sides of the square decrease in length?
Have you ever chewed on a wintergreen mint in
front of a mirror in the dark? If you have, you may
have noticed some sparks of light coming out of
your mouth as you chewed on the candy; and,
without knowing it, you have experienced a
physical phenomenon called triboluminescence. In
this problem you will analyze some of the key
elements of triboluminescence in wintergreen
candies.
When you break a sugar crystal with your teeth, energetic electrons, released by the broken chemical
bonds, collide with nitrogen molecules in the air. As a result of these collisions, the electrons in the
nitrogen molecules jump to a state of higher energy; when they decay to their ground state, radiation
is emitted.
▼ Part A
Imagine that an electron in an excited state in a nitrogen molecule decays to its ground state,
emitting a photon with a frequency of 8.88×1014 Hz. What is the change in energy, AE, that the
electron undergoes to decay to its ground state?
Express your answer in electron volts to three…

- Why electric cars (which are amazing) still stink at towing and going up mountains. A family in Charlotte wants to drive to a campsite next to Mt. Mitchell. Their trip will take them 2km up in elevation. They have the choice of taking their top-of-the-line Tesla model S P100D, which when fully charged has 100 kWh of stored energy in the batteries (and for this problem is 100% efficient at converting its stored energy into kinetic energy) and a mass of 2200kg, or their choice of taking their 2021 Ford F-150. Gasoline has an energy density of 34.2 Megajoules per liter. The family owns the smallest 2021 Ford F-150, and so it has a fuel tank of 23 gallons. Assume the F-150's engine is able to convert 30% of the energy stored in its gasoline tank into kinetic energy (typical efficiency for gasoline engines), with the rest of the stored energy in the gasoline lost to heat. The mass of this model F-150 is about 2000kg. They are going to tow their big pop-up trailer to the campsite.
