'C' and 'D' are the same statement, and none of the 3 choices
is good.
Electrical energy is produced in a generator, a solar panel, or
a battery, not in things with resistance.
From the generator or battery, current flows through a circuit of
one or more components.
The greater the resistance of a component, the more energy is
LOST as the current flows through it. The component dissipates
the energy in the form of heat.
Answer:The Poynting vector SS represents the flow of energy in an EM field. Specifically, if uu is the energy density of the field, the Poynting vector satisfies the continuity equation for it:
∂u∂t+∇⋅S=0
∂u∂t+∇⋅S=0
in vacuum. (This is Poynting's theorem.)
In your particular problem, EE and BB are perpendicular and their cross product is proportional to the product of their amplitudes. Thus
Sz=cμ0B2.
Sz=cμ0B2.
You then have to use your knowledge of BB to work out SS.
Explanation:
Scientist would check what other scientists have said before they come up with their own scientific question. That way they can record the results from the others and compare them with their own findings when they conduct their own experiments and record the findings.
