i had so much fun making up this physics quiz....

I hope my students appreciate my humor. Here are a few sample questions from my quiz (based on actual classroom events):

1. When the entire sixth-period physics class simultaneously drops its pens on the floor, it produces a sound with a 30-dB rating. If the sound of the entire class dropping their books on the floor is 1000 times more intense than the pens dropping, find the decibel rating of the books falling. (Don't try it....)
2. A certain physics student sees a cockroach in the classroom, and lets out a high-pitched scream. If the student’s scream has a wavelength of .57 meters and the speed of sound in air is 345 meters/second, what is the frequency of the scream?
3. The cheerleaders at the football game want the entire stadium to hear their cheers. A person on the front row is 3 meters away from them and can hear them with an intensity of 100 W/m^2. If the lowest intensity that a human can detect is .75W/m^2, how far away can a person be sitting and still know that when they yell blue, he yells gold?
   

I have lots of cheerleaders in my class. I hope they know just how funny I am. Hehe.
