<h2>
Answer:</h2>

<h2>
Step-by-step explanation:</h2>
If resistors are in series, so the current
is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

is the total resistance
. Moreover:

Therefore:

Answer:
k=27
Step-by-step explanation:
Answer:
The correct answer is B
Step-by-step explanation:
I know this is the answer because I took the test and got it right.
Answer:
The distance is dependent
Step-by-step explanation:
Time is always the dependent variable because time will always stay the same when other things change, such as distance.
