Explanation:
It is given that,
Current carried in the conductor, I = 14.7 A (+x axis)
The magnetic force per unit length on the conductor, (-y axis)
The magnetic force is given by :
B = 0.0085 T
According to right hand rule, the direction of magnetic force can be calculated. So, the direction of magnetic field is along +z axis. Hence, this is the required solution.
The combined speed of the plane and the wind is 249.35 km/h.
<h3>Relative speed</h3>
The relative speed of the plane due to speed of the wind is calculated as follows;
Let the direction of the plane be horizontal direction.
<h3>Speed of the wind</h3>The speed of the wind is calculated as follows;
The combined speed of the plane and the wind is calculated as follows;
V = 275 km/h - 25.65 km/h
V = 249.35 km/h
Thus, the combined speed of the plane and the wind is 249.35 km/h.

Answer:
None of the wavelength is in the visible range
Explanation:
Constructive interference of the reflected waves for different wavelengths can be estimated using:
λ = 2nd/m
where m is 1,2,3, ...
Therefore:
m=1, λ = 750 nm
m=2, λ = 750/2 = 375 nm
The limits of eye's sensitivity is between 430 nm and 690 nm. Beyond this range, the eye's sensitivity drops to approximately 1% of its maximum value.
