    Torsional Pendulum Uses and Experiment Re-Testing

    Can you please tell me, where can a torsional pendulum be used in every day life as an application? And how can this experiment be re-tested more accurately and preciselly (by using different apparatus)? Thank you guys

    Question on acceleration and string-HELP

    I need big help on this question guys: One test for the effects of the acceleration of gravity is to tie a set of weights to a string, with the second lowest searated from the lowes by L0, the third lowest from the second lowest by L1, and so forth, and to then drop the string. Suposing that...

    How Does Oil's Behavior on Water Demonstrate Molecular Structure?

    Well, I got 4.085x10^22 molecules, and when I divided with the area, I got 2.723x10^15. Is that my final answer??

    How Does Oil's Behavior on Water Demonstrate Molecular Structure?

    That is the question. I don't know, it wasn't stated in the question.

    How Does Oil's Behavior on Water Demonstrate Molecular Structure?

    The question says: Suppose that oil consists of molecules of CH2. This means that 1 mol of oil, consisting of 6.02x10^23 molecules, has a mass of 14g. One mililiter of oil has a mass of of 0.95g. When this much oil is poured on water, it does not spread forever but spreads unti it makes a...

    How Can I Solve These Vector Problems for My Homework?

    I guess I have forgotten many things about vectors, including their properties. So if the dot product of two perpendicular vectors would equal zero, how can that help figure out the most general vector in the yz-plane that is perpendicular to that vector A, in the previous post given.

    How Can I Solve These Vector Problems for My Homework?

    Scalar product of two perpendicular vectors equals zero, right?, since cos(alpha) of 90 degrees is zero, therefore it should equal to zero.

    How Can I Solve These Vector Problems for My Homework?

    Can someone help me with the following questions for homework? 1. Consider the vector A=7i + 3j - 6k. Find the most general vector in the yz-plane that is perpendicular to A. 2. Show that the magnitude of the vector product of two vectors is the area of the parallelogram for which the two...
