A: makes work easier to do.
The correct answer is "an attractive force" between the wires.
Let's see why. Assume we have wire A on the left and wire B on the right, and that the current in both wires go upward. First, let's find the direction of the magnetic field produced by wire A at wire B: by using the right-hand rule, we see that since the current (the thumb) goes upward, the magnetic field (given by the other fingers) at wire B is directed inside the paper.
Then we can apply again the right-hand rule to see what is the force on wire B. The index gives the direction of the current (upward), the middle finger the direction of the magnetic field (inside the paper), and the thumb gives the direction of the force: to the left, so toward wire A. This means the force is attractive. (you can re-do the procedure on wire A, and you will find the force on wire A is directed toward wire B)
Answer:
integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive
Explanation:
and this is biology not physics
Answer:
Reading is close to (b) 13.44 which is the best estimate of the period
Associated error, 
Given:
Solution:
1.The best estimate of the period can be calculated by the mean of the measurements and the one closest to the mean is the best estimate of the measurement:
It is close to 13.44 s
2. Associated error is given by:
where
n = a, b,......, e
Now,
Mean Absolute Error, 
3. The assumption behind the estimation is population is considered to distributed normally.
2s
Explanation:
Given parameters:
Current = 0.835A
Quantity of charge = 1.67C
Unknown:
Time taken = ?
Solution:
The quantity of electricity Q in coulombs is the product of the current I and time t.
Q = I x t
Q is the quantity of electricity in coulombs
I is the current
t is the time taken
input the values and solve for t;
1.67 = 0.835 x t
t = 
= 2s
