    Guess the Mechanism help (Organic Chemistry)

    So I was able to figure it out myself. Apparently, this is a pinacol rearrangement (http://en.wikipedia.org/wiki/Pinacol_rearrangement), which would explain many things...namely that we never even covered it in lecture at this point. >.>

    Alkene Nomenclature: Question 1 - Genius Attempt!

    1. I made up this problem myself in order to practice. I stumped myself. I'm such a genius, I'm aware It's basically alkene nomenclature with the E,Z naming scheme.2. Picture See below. I've taken the liberty of already numbering the longest chain.The Attempt at a Solution Without the double...

    What Are the Physics Behind Bouncing on a Trampoline?

    I was hoping that somebody could explain the physics behind a person bouncing up and down the trampoline. I know the basics as far as what happens to Kinetic Energy, Elastic potential energy, and gravitational potential energy...but there certainly has to be more than this, right? Can someone...

    Problems pertaining to centripetal force

    Ah, that makes sense. I got .125N as a result and this appears to be the correct answer. Still, I'm not entirely sure about part B for this problem. Should I draw a free body diagram for that part?

    Problems pertaining to centripetal force

    So this is what I ended up doing: TSB = (.05kg)(.837)2/(.14) I got the velocity by doing 2∏*(.28m) / 2.1 seconds I got an answer of .250N exactly...but apparently this is still wrong. What exactly am I not doing here?

    Problems pertaining to centripetal force

    But why would the problem say that it's going in a circle then? I'm really confused. So would I need to do 2∏*(.28) / 2.1 seconds to get the velocity? If this is correct, then would I be able to plug it into the equation I set up for myself successfully? So I should just scratch the "+ mg" I...

    Problems pertaining to centripetal force

    Homework Statement A golf ball with mass m = 0.05 kg is tied to a massless string of length L = 0.28 m. The ball is made to swing in a circle such that the string is horizontal throughout the motion. The ball makes one revolution every t = 2.1 s. m = 0.05 kg L = 0.28 m t = 2.1 s Homework...
