    Changing pitch in frequency ratio?

    Thanks! And by the way, a very happy new year to you haru! :D May it bring you many new experiences.

    Changing pitch in frequency ratio?

    Ohh, the only way I was picturing it was the strings being slackened or maybe a reversal of elastic elongation. :P Too much thought into a simple question.

    Changing pitch in frequency ratio?

    Homework Statement Homework Equations v=fΛ v=√(T/μ) The Attempt at a Solution I know I'm supposed to make an attempt, but I can make heads nor tails of this. Are they changed in a constant ratioo? Does the tension come into play? The answer given is 0.16m

    Moment of Inertia power plant energy

    If we integrate from r2 to r1 we get 1/2m(r1^2 - r2^2) right?

    Moment of Inertia power plant energy

    Chevelle probably checked wiki for the moment of inertia of an annulus like I did, haha.

    Elastic and Inelastic problems

    1) The plane had an initial velocity when the pilot was sitting in it. As the pilot jumped backward with a certain momentum, an equal amount was imparted to the plane in the opposite direction, which is the direction of the plane. This final momentum of the plane, divided by the mass of...

    How can the kinetic energy ratio be calculated after a bullet collision?

    2.48 x 10^-3 if we include the key of the first block, 1.943 x 10^-3 if we don't.

    How can the kinetic energy ratio be calculated after a bullet collision?

    The Kinetic energy after should probably include the KE of the first moving block too.

    Why do component vectors not work ?

    I said the same result would be produced if you placed two masses of msinθ and mcosθ along the axes at ry and rx distance away. Sorry if my answer was confusing.
