Part A: To find how much the sun produces in 2.45 · [tex]10^3[/tex] , we need to multiply the rate per second by the number of seconds we want the answer to have. This gives us:
2.45 · [tex]10^3[/tex] · 3.9 · [tex]10^{33} [/tex] =
= 9.555 · [tex]10^{36} [/tex]
That gives the answer of 9.555 · [tex]10^{36} [/tex] ergs
Part B: The more reasonable measurement of the diameter of a blood cell is 7.4 · [tex]10^-3[/tex] mm. That's because by saying the diameter of a blood cell is 7.4 · [tex]10^3[/tex] mm, you are saying the diameter is 7.4 meters!
