To solve this problem it is necessary to apply the concepts related to Wavelength depending on the frequency and speed of light.
The equation that meets these parameters is given by
Where,
c = Speed of light
f = Frequency
Our values are given as
velocity of light in free space
f = 2Hz
Replacing we have that
Therefore the correct answer is B.

Explanation:
<em>Given data:</em>
100-turn coil
mean length of central leg = 5.5 cm
mean length of outer paths = 15.5 cm
relative permeability = 2000
cross sectional area ( A ) = 1 cm^2
distance x = 1 cm
attached below is a detailed solution
Explanation:
Speed of the marathon runner, v = 9.51 mi/hr
Distance covered by the runner, d = 26.220 mile
Let t is the time taken by the marathon runner. We know that the speed of the runner is given by total distance divided by total time taken. Mathematically, it is given by :
t = 2.75 hours
Since, 1 hour = 60 minutes
t = 165 minutes
Since, 1 minute = 60 seconds
t = 9900 seconds
Hence, this is the required solution.
