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 diameter of a human hair:
1.8 ⋅ 10−2 mm or 1.8 ⋅ 102 mm? Justify your answer. (5 points)

Using the multiplication operation, the Number of ergs produced in is

Total number of ergs produced can be calculated thus :

Therefore, the Number of ergs produced in is

B.)

Due to the very small measure of the diameter of the human hair, a measure of would be too large, Hence, the value would be more appropriate
