Homework Statement Determine the height of a 91 lbs. gold cube. Homework Equations I'm not really sure which equations are relevant here... this is an Honors Physics problem for my girlfriend, but she asked me to attempt and I'm in Physics. Anyways, I thought of and only found a few I...

In the next couple weeks, my senior year in high school will begin... and with that comes some decisions I'll be having to make. I'm hoping to find some answers to a couple questions I have, here. One: To begin, engineering is the general field I'm going to be pursuing, however which specific...

I believe it's "syn-eck-duh-kee". That word just came up in APE a couple days ago, actually. Coincidental timing! :)

Thank ya. But my friend ended up showing me how I was to go about it:

Homework Statement Draw out the electron dot diagram for isopropyl alcohol. Homework Equations C[SIZE="1"]3H[SIZE="1"]7OH The Attempt at a Solution Carbon = 4 valence electrons, multiplied by 3 carbons gives us 12 valence electrons for carbon. Hydrogen = 1 valence electrons, multiplied by...

I knew that the differences between the Spanish dialects were there, but that much so? I know a girl whose native language is Argentine Spanish, and then I know a few people whose native language is Northern Mexican-Spanish, and a couple of my friends are from Spain and speak their Spanish. Now...

The driving mechanism is just a 6 lbs. weight. So, the throwing arm is driven by the weight. But then there is a sling included as well -- attached to the end of the throwing arm. The sling is then driven by the throwing arm, which is driven by the weight, correct? So the force produced by the...

I haven't taken any kind of physics class yet, being I'm only in eleventh grade and physics is next year. So, I'm not sure where to begin on any of that. If you wouldn't mind, could you get me started, if not just the equations needed. But just from a guess, I would think that there would be...

For my Engineering III class we're designing trebuchets. But, specifically, my question is: If I have the arm swing forward and let it go as it does normally, where it swings through and then relaxes back to a 90 degree position, will there be more force present in throwing the object...
