Question 21

What does the exponent in scientific notation tell you?

Answer 21

how many zeros there are

Question 22

In dimensional anaylsis, where should your given measurement (measurement that you are converting to another unit) be?

Answer 22

numerator of first box

Question 23

How do you know when you have the end-result unit in dimensional analysis?

Answer 23

all other units are cancelled (ends up at top as 1 unit)

Question 24

For dimensional anaylsis, what do you need to do once you plugged in all the numbers in the grid correctly?

Answer 24

multiply all the top numbers, separately multiply all the bottom numbers, then divide product of top numbers by product of bottom numers

Question 25

If the given measurement has (unit per unit), what does that mean in terms of our grid layout for the first box?

Answer 25

numerator of the first box will be the unit before “per”, denominator of the first box will be the unit after “per”

Question 26

If the given measurement has (unit per unit), what does that mean in terms of our grid layout for when we finished conversion for one unit and now need the other?

Answer 26

the unit of the denominator of the first box will cancel by putting the same unit as a numerator in a box, followed by its equivalent unit in the denominator
