Answer:
Beats are the difference in frequency.
(a) is correct option.
Explanation:
Beat :
Beat is the difference of the frequency of two waves.
The difference in frequency is equal to the number of beat per second.
Amplitude :
Amplitude of the wave is the maximum displacement.
Frequency :
Frequency is the number oscillations of wave in per second.
Intensity :
Intensity is the power per unit area.
Hence, Beats are the difference in frequency.
The magnetic flux is 2.6 x 10-3 Wb
<h3>
What is Magnetic flux?</h3>
Magnetic flux is the measurement of the total magnetic field that passes through a given area.
It is a useful tool for helping to describe the effects of the magnetic force on something that occupies a given area.
Area of triangle inside the field, A = 1/2 x 0.1 x 0.2 x sin 60 = 0.00866 m2
therefore, magnetic flux = B x A = 0.3 x 0.0086 = 2.6 x 10-3 Wb
(B) Applying Lenz's law, the direction of the current will be clockwise
