Analysis Questions
4. Look at the data table and graph for the 25-turn electromagnet. With the 1.5 V battery, the electromagnet picked up an average of ___ paper clips, and with the 6.0 V battery, it picked up an average of ___paper clips.
a. About how many times stronger than the 1.5 V battery is the 6.0 V battery? Show your work.
Work shown to arrive at the
b. What is the approximate ratio of the number of paper clips picked up using the 6.0 V battery to the number picked up using the 1.5 V battery? Show your work.
Answer expressed as either a simplified whole number ratio or fraction, not a single digit:
Work shown to arrive at the
c. What type of relationship does this demonstrate? (Circle, highlight, or delete one) direct inverse
d. How did you decide which relationship to choose for your answer in part c? Show your thought process using the numbers in part b as evidence and a written explanation of your choice as the claim
5. Look at the data tables and graphs for both the 50-turn electromagnet and the 25-turn electromagnet. With the 9.0 V battery, the 50-turn electromagnet picked up an average of paper clips, while the 25-turn electromagnet picked up an average of paper clips (at the same voltage).
a. What is the ratio of the number of turns of the 50-turn electromagnet to the number of turns of the 25-coil electromagnet? Show your work.
Answer expressed as either a simplified whole number ratio or fraction, not a single digit:
Work shown to arrive at the
b. What is the approximate ratio of the number of paper clips picked up by the 50-turn electromagnet at 9.0 V to the number of paper clips picked up by the 25-turn electromagnet at 9.0 V? Show your work.
Answer expressed as either a simplified whole number ratio or fraction, not a single digit:
Work shown to arrive at the
6. What does doubling the number of coils do to the strength of the electromagnet? Show your thought process using the numbers from your data table as evidence and a written explanation of your choice as the claim.

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
