Question

4. What are the controls in this experiment? (This question may have more than 1 answer. Remember these stay the same for the experiment. They are not changed and are used for comparison.)
A. string length
B. frequency
C. wavelength
D. measuring devices

5. What educated guess—HYPOTHESIS—should be made about this experiment? (Look at your data to decide).
A. If the length of the string is short, then the frequency is high.
B. If the length of the string is long, then the frequency is high.
C. If the length of the string is short, the wavelength is long.
D. If the length of the string is long, the wavelength is short.

6. What tool was used to collect the data in the experiment?
A. ruler B. timer C. oscilloscope D. laser

Data and Observations
7-14. Record your observations from the first part of the experiment in a data table.



15-20. Create a graph that shows the relationship between the string length and the frequency of sound produced.




Conclusions
21-25. What conclusions can you draw about the relationship between string length and frequency and string length and wavelength? (There will be multiple answers to this question.)
A. longer strings created higher frequencies
B. longer strings created lower frequencies
C. shorter strings created higher frequencies
D. shorter strings created lower frequencies
E. shorter strings had shorter wavelengths
F. shorter strings had longer wavelengths
G. longer strings had shorter wavelengths
H. longer strings had longer wavelengths

Answer 1

i promise these r the last ones.........

Answer 2

picture of the experiment

Answer 3

4. this one would either be B or D but i would think D because that is i believe basicly a control as it has the word device and it wants to know the control

Answer 4

5. i am not too sure about number 5 but if i have a ges i would say Also D

Answer 5

no i think i know 5 im thinking ruler

Answer 6

just maybe

Answer 7

ok number 6. what tool was used to collect the data it can not be A because that is just measuring not collecting so eliminate that B u can also eliminate because a timer is to like count down something a laser is i believe some sort of weapon to pertect something u do not want stolen so eliminate that so it would be C

Answer 8

here is the graph for 7-14

Answer 9

oooh ight

Answer 10

let me think about number 7 realy quik

Answer 11

ok did u get the graph??

Answer 12

yes

Answer 13

ight just checking

Answer 14

but FYI i hope i am helping u correctly because i am not doing Science for my school right now until i finish history and i am also not to good at it i am also in 8th grade

Answer 15

ok ur good lol

Answer 16

number 1 here i think is short and then the others i am not to sure but i think the others might all be long but not positive

Answer 17

ok

Answer 18

ok i am going to skip ahead to the last question and i am not too positive with this one and i think that this one is G and C

Answer 19

lol ok btw for 15-20 do u need the chart??

Answer 20

no it says u need to create a graph

Answer 21

ight
