    Initial acceleration problem: Two children on a frictionless floor

    Homework Statement A girl of the mass 30kg and a boy of the mass 45kg sit on a frictionless floor holding two ends of a rope. The boy pulls on the rope. The girl moves towards the boy with an initial acceleration of 3ms^-2. The boy A. Moves towards the girl with an initial greater acceleration...

    High School Convert 50ml Honey Volume to Meters

    Ahh thank you. Given what you just said (just checking to be sure) this means that, 1ml= 1(cm)^3 50ml=x x=50(cm)^3 in meters x=50x10-^6 ?

    High School Convert 50ml Honey Volume to Meters

    Using a graduated cylinder I measured the volume of honey to be 50ml. How do I convert this into meters for the volume to be in meters because it's currently in ml?

    Solving a Trigonometry Problem with Tan A and Tan B

    Homework Statement The lines L1 and L2 with equations y=2x and 3y=x-1 respectively,are drawn on the same set of axes. Given that the scales are the same on both axes and that the angle L1 and L2 make with the positive x-asis are A and B respectively, write down the value of Tan A and the value...

    Is Binding Energy Equal to the Strong Nuclear Force?

    Thank you Sir. In some worked examples I see that they take the mass of the electrons into account and some do not. So I just wanted to confirm. Thank you very much.

    Is Binding Energy Equal to the Strong Nuclear Force?

    Homework Statement I have two questions. 1.The definition of binding energy is the work needed to split the nucleus into its constituent protons and neutrons. The strong nuclear force keeps the nucleus together hence is it right for me to say the binding energy is equal to the energy of the...

    Why Does Cyclotron Frequency Depend Only on Magnetic Field Strength?

    Sorry for the long response. Now that I think of that way it does make sense. Thanks.

    Why Does Cyclotron Frequency Depend Only on Magnetic Field Strength?

    So why does it depend on the magnetic field strength? Is the reason similar to I said?

    Why Does Cyclotron Frequency Depend Only on Magnetic Field Strength?

    According to the equation F=BQ/2pieM the frequency depends on the magnetic field and not the speed or radius of the particle. Can someone please explain why? B= Magnetic field strength Q=Charge M=Mass I think it's because of the force felt due to magnetic field so the time it reaches the dees...
