First calculate C_2 = (mg / (v^2 * r^2) where r is unknown, then calculate F = C_2 * r^2 * v^2 I presume this question is from Walter Lewin's Physics course

Thank you ma'am

Ma'am please explain whether still follows any verb?

Thank you so much teacher

I want Maximum and minimum values of acosx+bsinx+c proof

Thank you Bob, that makes a lot of sense

Never mind, I figured out how to do it and got 1.2 x 10^-18 s

Never mind I figured it out

Oh wow it was a lot easier than I thought... Thanks so much!

I had this question bookmarked and happened to come back. c = fλ 3 x 10^8 = f(0.016) f = 18,750,000,000 Hz E = hf E = (6.63 x 10^-34)(18,750,000,000) E = 1.24 x 10^-23 J P = E/t 1.04 x 10^-5 = (1.24 x 10^-23)/t t = 1.2 x 10^-18 s

Apparently my teacher was wrong?? I finally looked at the markscheme while studying for the mocks and it's TOTALLY different. And a lot simpler. Use: I = Initial I(cosθ)^2 Arrange that into: Initial I = I/(cosθ)^2 (12 µ)/(cos30)^2 1.6 x 10 ^-5 W

The time should be 1.9 x 10^-4 s using that new power.
