Distance is indeed a scalar amount that also refers to "<em><u>how the ground an object has encased</u></em>", and the Displacement is a vector thing that leads "<em><u>to the extent to which an object is located</u></em>", and the further calculation can be defined as follows:
Given:
distance= 70 miles
displacement = 20 miles
- Displacement formula:
![\bold{Velocity = \frac{displacement}{time}}](https://tex.z-dn.net/?f=%5Cbold%7BVelocity%20%3D%20%5Cfrac%7Bdisplacement%7D%7Btime%7D%7D)
- Distance formula:
![\bold{Distance = speed \times time}](https://tex.z-dn.net/?f=%5Cbold%7BDistance%20%3D%20speed%20%5Ctimes%20time%7D)

Answer:
(a) B = 5.6 micro Tesla
Explanation:
Current in the wire, i = 140 A
distance, r = 5 m
The formula for the magnetic field at a distance r due to the current carrying wire
![B=\frac{\mu _{0}}{4\pi }\times \frac{2i}{r}](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B%5Cmu%20_%7B0%7D%7D%7B4%5Cpi%20%7D%5Ctimes%20%5Cfrac%7B2i%7D%7Br%7D)
![B=10^{-7}\times \frac{2\times140}{5}](https://tex.z-dn.net/?f=B%3D10%5E%7B-7%7D%5Ctimes%20%5Cfrac%7B2%5Ctimes140%7D%7B5%7D)
B = 5.6 x 10^-6 Tesla
B = 5.6 micro Tesla
(b) As the magnetic field of earth at this site is 20 micro tesla so the magnetic field due to current carrying wire interfere the magnetic compass.
