Hair Combing Physics Action!

While I was combing my hair today, I realized that there were some electrical physics concepts going on. In fact, they had been going on for pretty much every day of the year I had combed my hair. Which comes out to about 36 days. When running the comb through my hair, electrons from my hair, through physical contact, travel to the comb. This causese the comb to have more electrons and have an overall negative charge. My hair became positively charged because it loss electrons, meaning that my hair had a greater amount of protons than it did electrons.

Waves

This is a picture from a while back, at that new Finding Nemo ride at Disneyland. With Submarines. Though I did not realize it at the time, there is a lot of physics action going on here. In this picture, the submarines moving around in the water are causing a disturbance and generating waves. The submarine ride is most likely generating bow waves. As the submarine moves forward, the waves will pile up in front. This happens becauase the submarine is moving faster than the waves that it is producing. The continuous overlapping of the wave crests makes the front end of the waves form a v shape, characteristic of bow waves.
