    Graduate Accretion rate onto a WD over time (relation)

    Hi all, I was wondering if there is a correlation between the accretion rate and time. I think it should decrease as time increases, but I can't find the right correlation

    Deriving Ball Movement on Northern Hemisphere with Rotating Reference Frame

    Thank you :) You're very kind! I'm still stuck and not getting this. I'll try to read some more online and maybe I'll understand what I'm missing and get the exact equation they're looking for

    Deriving Ball Movement on Northern Hemisphere with Rotating Reference Frame

    Ok! I think I understand what you wrote. I'll try to derive the equation for r.. hopefully this works out. You are superb!

    Deriving Ball Movement on Northern Hemisphere with Rotating Reference Frame

    Thank you. So this is where I got so far: the equation of motion is given, in this case, by: 0 = m*Ω x (Ω x r) - 2m * (Ω x v) I could eliminate the mass from both sides. and I also know that the motion is perpeniduclar to the rotation axis, so the coriolis force could be just: 2*m*w*v so I'm...

    Deriving Ball Movement on Northern Hemisphere with Rotating Reference Frame

    I have a ball of mass m that is situated on horizontal plane on the northern Hampshire. I am asked to show that the ball is moving, clockwise, in a manner of r = v / ( 2Ω*sin(λ) ) where v is the ball's velocity, Ω is Earth's angular velocity, and λ is the terrestrial latitude So here's what...
