Question

More help with significant figures?
Thanks! ^.^

Answer 1

6271 m / 59.7 s

Answer 2

you know that your answer has to be 3 sig figs because 59.7 is 3 sig figs

Answer 3

so just divide normally and round until you get 3 sig figs :)

Answer 4

So when I divide I get 105.0418.... (continues on)

Answer 5

what do you round it to to get 3 sig figs?

Answer 6

105.04 ?

Answer 7

close, but .04 are also sig figs so you'd end up with 5

Answer 8

the answer would be 105 :) remember to keep the decimal off because then you'd have 105.0 which is 4 sig figs

Answer 9

Okay, okay, but hold on a sec...
Significant figures are the SI units...
Now, we have to convert m to s...
Break that down a bit for me..

Answer 10

could you not leave it as 105 m/s?

Answer 11

distance and speed need to be in same precision is it ?
division wont affect significant figures ?

Answer 12

I have no clue, hun.

Answer 13

me neither

Answer 14

because miles is a unit of distances, seconds is a unit of time

Answer 15

distances wouldnt convert to time, so it'd just stay m/s

Answer 16

its kinda like miles per hour

Answer 17

Okay, so we can't do anything with those then, right?

Answer 18

yepyep.

Answer 19

just worry about the actual numbers, not the units :)

Answer 20

Okay, so all I need is what's before the decimal point, correct?

Answer 21

in this case, yep

Answer 22

Okay.
\(\Large\bf\rlap{\color{red}{\bigstar~T}\color{gold}{H}\color{greenyellow}{A}\color{lime}{N}\color{cyan}{K~}\color{blue}{Y}\hspace{0 pt}\color{purple}{O}\color{magenta}{U}\color{orchid}{!~\bigstar}}{\color{black}{\; \bigstar~THANK~YOU!~\bigstar}}\)

Answer 23

do you know the sig fig rules?

Answer 24

because that kinda helps a lot, obviously :P

Answer 25

I have a list of them, but I don't have them memorized.

Answer 26

any number that isnt 0 is always sig, any 0's between non zeros like 101 are always sig, the last unit in a number is always sig like the 4 in 1.024, and any 0 left to a decimal point are always sig

Answer 27

the lest unit one only applies if theres a decimal point tho

Answer 28

Okay, that makes sense.

Answer 29

those make sense? because i know the rules my teacher made no sense until he gave them to us in layman terms

Answer 30

cool, glad i could help

Answer 31

Yes, they make sense, I've learned this stuff before, but I forgot it all haha.
This is for my Physics/Chemistry class. :p

Answer 32

figured :P

Answer 33

Thanks again. ^.^
