Part A: The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in
1.55 ⋅ 10^7 seconds? Part B: Which is the more reasonable measurement of the distance between the tracks on a CD: 1.6 ⋅ 10^−3 mm or 1.6 ⋅ 10^3 mm?
1 answer:
(3.9 * 10^33)(1.55 * 10^7)
3.9 * 1.55 = 6.045
10^33 * 10^7 = 10^40
6.045 * 10^40 <=== ur answer for the 1st one
1.6 * 10^-3 = 1.6 * 1 / 10^3 = 1.6/1000 = 0.0016 <== its probably this one...the 1.6 * 10^-3
