at 10:08 how did you get the value of x (6.48×10^-4)
@doclenczewski727
@doclenczewski727 3 года назад
5.88x10^-6 x 0.0714 = 4.198x10^-7. Then the square root of 4.198x10^-7 = 6.48 x 10^-4

I had to spam the like button real quick. I kept using the equation from my textbook which says that n1 squared is the final value and n2 squared is initial. I kept getting the wrong answer thinking it was me, but its actually my expensive textbook 🥴🥴. I did it this way and go the right answer. Thank you
