Energy
because once the light hits her eyes energy flows through her body so the answer is A energy
The answer is
C. periodic fluctuations in the intensity if sound waves.
Answer:
The time rate of change of flux is 
Explanation:
Given :
Current 
A
Area of plate 
Plate separation 
m
(A)
First find the capacitance of capacitor,
Where 
F
But 
Where 
Now differentiate above equation wrt. time,
Therefore, the time rate of change of flux is

Answer:
We show added energy to a system as +Q or -W
Explanation:
The first law of thermodynamics states that, in an isolated system, energy can neither be created nor be destroyed;
Energy is added to the internal energy of a system as either work energy or heat energy as follows;
ΔU = Q - W
Therefore, when energy is added as heat energy to a system, we show the energy as positive Q (+Q), when energy is added to the system in the form of work, we show the energy as minus W (-W).
