Re: Solutes and Solvents

A fast-and-dirty way to get what the teacher wants (not the right answer- it's an important distinction) is probably to just say the liquids are all solvents and the solids are all solutes. Not sure how resin is classed.

Re: Stupid School Policies

Stupid School Policy: Making kids get up and come to school every day. Especially at 7:30 in the morning. I can barely remember any of my first-period classes for this very reason. College and 10:00 AM wake-ups are MUCH better. To any graduating high-school seniors: do not take 8:00AM classes in co...

One of my friends managed to get -8 out of 100 on a Language Arts exam in 8th grade. Negative? How did she penalize him down to negative? I had an English teacher who took off five points for each use of any form of "to be." Before she capped it at twenty points, there were people with ne...

Re: Australian man claims perpetual motion machine

Basically what you're saying is that gravity doesn't contribute energy to moving the ball because it's applied uniformly. In other words, the ball isn't rolling in this case due to gravity at all, only to the initial energy. Makes sense. Uniformity is irrelevant. Gravity doesn't contribute energy t...

to draw energy from this you would need a gear that is free to rotate hooked up to a turbine? would the power be dependent on the mass or radius of said turbine? what would you need for say 1 MW of power?

Re: work done by a pump

Use the cross-sectional area of the hose, the density of water, and the velocity to determine kg of water leaving the hose per second. Use this metric and the vertical distance that the water is pumped to get power. HINT: 1 Watt= 1 kg*m 2 /s 3 . EDIT: Which gives me... 48 Watts. I'm stumped. EDIT2: ...

Re: AP courses

At Georgia Tech, most of the Calc 1 teachers pretty much assume that you took at least AP Calc AB and are just reviewing. This screws over anyone who didn't take it in high school (several of my friends).
