Given Information:
Current = Ii = 7.2 A
Number of turns inner coil = Ni = 140
Number of turns outer coil = No = 180
Radius inner coil = ri = 0.015 m
Radius outer coil = ro = 0.023 m
Required Information:
outer coil current = Io = ?
Answer:
Io = 8.6 A
Step-by-step explanation:
We have two coils, subscript i denotes inner coil and o denotes the outer coil.
According to the Biot-Savart Law
B = μ₀IN/2r
we will equate the inner and outer magnetic fields
Bi=Bo
μ₀IiNi/2ri = μ₀IoNo/2ro
μ₀ and 2 cancels out
Io = Ii*Ni*ro/No*ri
Io = 7.2*140*0.023/180*0.015
Io = 8.6 A
Therefore, a current of 8.6 A is needed to flow in opposite direction so that the magnetic field is opposite and the net magnetic field will be zero.

Answer:
C The bending of wind because of Earth’s rotation
Explanation:
The Coriolis effect is the bending of wind due to earth's rotation. It is responsible for a broad range of phenomenon on the earth surface.
It stems from the deflection of a moving bodies in a frame of reference that is constantly rotating.
The deflection or blending of wind as the earth rotates is caused by this effect.
Due to this, the wind moves towards the right at the northern pole and the left at the southern pole.
