    How Does the Index of Refraction Affect Light Speed in Different Materials?

    new question though... ok, so diamond has an index of refraction of 2.42. Suppose that a rectangular block of diamond is immersed in a tank of water and that a ray of light is passing through the dimaond makes an angle of incidence of 25 degrees in the diamond. What is the angle of refraction...

    What Does g Represent in the Fluid Mechanics Equation P = Patm + pgh?

    THANK YOU SOO MUCH! now i can finish my problem. one more though... in this equation for fluid mechanics... F*sub*b = pVg Is the V for volume? becuase I'm given the dimensions of a box floating on water and I have to figure out how much of it is under water

    I NEED IMMEDIATE HELP for solving the magnitude and direction of current

    wow what a formula! i use F=2K'I/r
  12. B

    I NEED IMMEDIATE HELP for solving the magnitude and direction of current

    so the current on the second wire IS north, but now with the 10N repulsion, how do i find magnitude?

    I NEED IMMEDIATE HELP for solving the magnitude and direction of current

    oh ok neo devin
  14. B

    I NEED IMMEDIATE HELP for solving the magnitude and direction of current

    ok, so from my problem, the current on the second wire is up (north) and what does B stand for again?
