Part a: the sun produces 3.9 • 1033 ergs of radiant energy per second. how many ergs of radiant energy does the sun produce in 1.55 • 107 seconds? (5 points)

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 • 103 mm? justify your answer.

Part A) The sun produces ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in seconds?

by using proportion

therefore

the answer Part A) is

Part B) Which is the more reasonable measurement of the distance between the tracks on a CD: or ?

The distance between the tracks on a CD are very small. therefore it would be more reasonable to have a value of

therefore

the answer Part B) is
