Answer:
the question has some missing details i.e E = E0sin(kx -wt)y and B = B0sin(kx -wt)z
The variables E0 and B0 are the amplitudes.
option C is correct.
Explanation:
Compare the equation given with the general wave equation ; Y = Asin(kx - wt)
Where A is the amplitude
He had their masses and reactivity. I hope this helps.
Answer:
Explanation:
We have given that the battery has an internal emf of 9 volt
So E = 9 volt
Capacitance
It is given that on the terminal voltage is only 80% of potential difference
So V = 0.8×9 = 7.2 volt
We know that energy stored in the capacitor is given by
