When Mr. Beier takes off his glasses, he has inexplicable powers. One of which being his ability to oppose gravity. Will Mr. Beier weigh the same on the surface of the earth as he does 25 miles above the surface?
Pretty much, just slightly a little tiny bit less.

Humpty Dumpty (A miracle of nature being a massive 85 kg egg with eyes, legs, arms, a nose and a mouth) sat on the 8.5m tall great wall. Humpty Dumpty had a fall so great that all the kings horses and all the kings men couldn't put him back together again. Explain the severity of his fall by giving me the approximate kinetic Energy Mr. Dumpty posessed immediately before he made contact with the ground.
722.5J

Two giant hunks of metal are floating around in space with a gravitational attraction of 800N. If Mr. Beier stops time and moves one of them so that the distance between them is now doubled, what is the new gravitational attraction?
200 N

Define the term amplitude.
The displacement of a wave above or below the origin

If Vector shrunk the moon to exactly half its mass while it maintained it's same orbit around the earth, what would happen to the gravitational attractive force between the earth and the moon?
It would be reduced by 1/2

If the frequency of a wave is quadrupled, what will happen to its wavelength?
It will be reduced by 1/4

Why is it that the water in your pool is able to retain a higher temperature later into the night than the concrete surrounding it?
Water has a higher specific heat than concrete.

Will Ferrell hit a pop fly this year during spring training. If a baseball has a mass of .145 kg and immediately after it left contact with the bat, it had a speed of 30m/s, what was the Potential energy the ball posessed at the peak of its arch? Ignore air resistance.
65.25 Joules

According to Einstein, what creates the gravitational attractive force?
Every object bends or creates a warp in the time space continuum allowing objects to fall through the warp towards each other.

Mr. Beier just made a brick from scratch. In order to cool the 1 Kg brick from 99*C, he dropped it in 2 kg of water that was initially at 15*C. If the specific heat of a brick is 840 J/Kg*C and the specific heat of water is 4182 J/Kg*C, what is the final equilibrium temperature?
22.66*C
