one hundred milli- (100 times one one-thousandth):
102 ✕ 10−3 = 10(2 + [−3]) = 10(2 − 3) = 10−1 = 0.1 (100 ÷ 1,000 = 0.1)
one hundred micro- (100 times one one-millionth):
102 ✕ 10−6 = 10(2 + [−6]) = 10(2 − 6) = 10−4
How do we write one hundred nano- (100 times one-billionth)?
102 ✕ 10−9 = 10
We write ten micrometers as follows.
10 ✕ 10−6 m = 10−5 m
How do we write ten nanoseconds?
10 ✕ 10−9 s = 10 s
For this short response assignment, your job is to demonstrate your understanding of SI units and how they can be applied on an astronomical scale. To do this, answer each of the following with a brief explanation of the mathematics used to get there.The speed of light is 3*10^8 m/s (aka 300,000,000 meters per second). What is the speed of light in centimeters per second, kilometers per second, and miles per hour? (Hint: there are roughly 1.6 km per mile and 3600 seconds per hour) Remember to show the math; If light from the closest star to our solar system takes about 4.2 years to get to us, how far away is that star in units of Gm (aka Gigameters)? Again, explain your work.
How many times longer than the length of recorded history is the age of the universe?
I was also given that the length of recorded history is 10E11 s, and that the age of the universe is 10E18 s. But, when putting 10E18/10E11 = 10E7, I get the wrong answer.

- Suppose velocity of an object is 5.7 miles per hour. When asking this as a question, say, what is velocity in m/s -- meaning meters/sec then we think dimensional analysis: 1 mile = 5280 ft, 1 ft = 12 in., 1 m = 39.37 in., 1 hour = 60 min, 1 min = 60 s In short ft to in to meters; also hours to min to seconds. -- dimensional analysis. However, in all this, do we think that avg velocity = change in distance/change in time.
