Sorry bobpursely, but may I know what the E stands for in your formula? What is the Surface area of a glass bead that has the diameter of 11m? Express your answer to the nearest square mm. radius= .0055m radius^2= 5.5E-3 ^ 2=30.25 E-6m 4PIr^2= about 12*30.25E-6 m

Physics - Light & refraction
Basically what bobpursely is saying is that you are going from a high index of refraction to a low index of refraction, so you'll have total reflection inside the object. if you are going from air to water, then you are going from a low index to high index, so you won'...

You have it. Friction of course is present, and squeeks and grinding noises, those are energy.

I get the same answers as Mr. Pursley: If a*b = ab - b/a, 1)-3+-4*8 = -3 + (-4)*8 = 33 2)2*(4*8) = 2*(30) = 45 if a*b = (ab-b)/a, 1)-3+-4*8 = -3 + (-4)*8 = -3 + 10 = 7 2)2*(4*8) = 2*(6) = 3

Well, then the * is an operator, so 1) -3+-4*8=-3+ -32-8/-4=-3-32+2=-33 as I see it. I dont get either of your answers, but frankly, I am not certain of the function. ab minus b divided by a could be (ab-b)/a or ab - (b/a)
