Rearrange the equation to solve for the permeability of free space (μ0). Remember that the slope is the ratio of magnetic field to current or μ0 = 2R N B I . Hint: Substitute your value of slope into the equation in place of B / I. μ0 = T · m/A

Complete Question

The complete question is shown on the first uploaded image

Compare the percent error between your value and the accepted value of 1.26 times 10-6 T · m/A. (Use the accepted value given to three significant figures in your calculation.). 100% % error = %

The permeability of free space is

The percentage error is  % error = 5.25%

Explanation:

From the question we are told that

            The slope is   , and

Generally  

               So  

From the relation given in the question

 Where R is the radius of the coil  

             N is the number of loops of the coil = 10

Now from the question we are told that

substituting into the equation above

Substituting values

Generally the % error is mathematically represented as

                    %

Given that the accepted value is

      Hence substituting values

                      %

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
