Are there supposed to be multiple choices for this question?
Answer:
3.222 ohms
Explanation:
If the total wire had a resistance of 29 ohms, when cut in three, each piece will have a resistance of 9.666 ohms.
As these three pieces (R1, R2 and R3) are now connected in parallel, the equivalent resistance R can be calculated using this equation:
1/R = 1/R1 + 1/R2 + 1/R3
1/R = 1/9.666 + 1/9.666 + 1/9.666
1/R = 3/9.666
R = 9.666/3 = 3.222 ohms
The resistance between A and B will be 3.222 ohms
Answer:
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Deposition means that all the sediments, soil, and rocks are all compressed (tightly pressed into each other) and create sedimentary rocks.
I hope this helps! :)
