    A 5.0kg mass is accelerated from rest at the bottom of the 4.0 m long

    Homework Statement A 5.0kg mass is accelerated from rest at the bottom of the 4.0 m long ramp by a falling 20.0kg mass suspended over a fictionless pulley. The ramp is inclined 30º ramp from the horizontal, and the coefficient of kinetic friction = .26. a. Determine the acceleration of the...

    How Do Standing Wave Equations Relate to Harmonics and Wavelength?

    Homework Statement L = [(2n -1) / 4 ] lamda I don't understand what is this and also L = n lamda / 2 In my notes it only says f = c/ 4L for 1st harmonic f = 3c / 4L for 2nd harmonic.. etc Homework Equations The Attempt at a Solution

    Suppose in the previous problem m3 balances the see-saw by pulling now

    oh make sense. but u said ignore m3? why? torque = rF , so the force does not include m3g?

    Gr12 charge attraction repulation question

    and for this question Question:Two charges of +Q are 1 cm apart. If one of the charges is replaced by a charge of –Q, the magnitude of the force between them is Ans: the same Won't they either get attracted or repelled? then , the magnitude will change isn't it?

    Gr12 charge attraction repulation question

    I don't understand why the answer is B It make sense if the question is asking which one is the incorrect force since my diagram contain all the arrows except B..
