    Easy angular velocity question

    Homework Statement A solid disk with a radius of 1.4cm is a rest. The disk has 2.0m of string wound on to its circumference. The string is pulled off the disk by a constant force in a time of 7.3s. What is the final angular velocity of this disk? Homework Equations v = r*ω The...

    Subspace of Polynomials: \vec{}p(t)=a+t^2, where a is real

    Oh so since the coefficient of t2 is 1, t2 will never be multiplied by the scalar 0, and thus the entire vector never equals 0? What confuses me is that why can't we assume both a=0 and t=0? or alternatively, why can't we multiply both sides of P(t)=a + t2 by the zero vector?

    Subspace of Polynomials: \vec{}p(t)=a+t^2, where a is real

    Homework Statement Determine if all polynomials of the form \vec{}p(t)=a+t^2, where a is in real, are a subspace of \Re_{}n.The Attempt at a Solution the correct answer says that p(t) is not a subspace since the zero vector is not in the set. im trying to work this out and got P(0)=a+0=a is...

    Differential eqns or linear algebra?

    alright thanks, good to know. I'll take linear algebra, then multivariable calc, then differential eqns.

    Differential eqns or linear algebra?

    I'm in engineering. I need to take both of them eventually, just wondering which one I'd be better prepared for since I've only gone up to calc 2

    Schools How much does it cost to attend a university in California or Colorado

    Because of the CA budget crisis, all of the schools, including the community college I'm attending, are experiencing layoffs, class cancellations, etc. Also, the tuitition at the UCs has recently increased by 32%.

    Trouble understanding orbital hybridization

    If you have a good general chem book then it basically just takes a lot of reading until you understand these concepts. This section for me, along with entropy were the hardest parts about chem 1 so far. Just remember that the central atom of the molecule must make enough hybrid orbitals to...

    Chemistry Question: Correct Chemical Formula for AgZ Compound Explained

    CaZ2 Ag ion has a charge of +1 which mean the charge on the Z anion must be -1. Ca ion has a charge of +2, so it takes two Z anions to bond with it.
