    High School Why does a vector have both a magnitude and a length?

    What's the difference between magnitude and size? I mean, how can I say that AB vector has a magnitude of 9 Newton, and its length is 4 cm.

    High School Why do radio waves pass through walls but visible light doesn't?

    Why do radio waves pass through walls while visible light can't? I guess this has something to do wit the wavelength. What I know is that higher wavelength means higher ability of penetration. So why radio waves penetrate obstacles?

    Undergrad Are the resultant force law and parallelogram rule the same thing?

    I just want to know the difference between those rules: 1. R^2 = F1^2 * F2^2 + 2*F1*F2*COS(the angle between F1 and F2) 2. The second is about the parallelogram rule, it says that the two vectors are added and their summation is the magnitude of the resultant. Which one is correct?

    High School Why longitudinal waves are waves?

    i know it's an absurd question, but why are longitudinal waves called waves although they aren't wave-like?
