What is the rms value of (a) the electric field and
(b) the magnetic field in the electromagnetic wave emitted by the laser
Answer:
a)
b)
Explanation:
To find the RMS value of the electric field, let's use the formula:
Where
;
;
Therefore
b) to find the magnetic field in the electromagnetic wave emitted by the laser we use:
;
;
Answer: The correct answer is (C).
Explanation:
Supply function:
Demand function:
S(p)=D(p), price for which supply is equal to demand:
After solving this above equation graphically, we will get the values of p.
1) p =96.236
2) p=( -118.258)
We will reject the negative value of p.
So, the value of p that price for which the supply equals the demand is $ 96.236 $96.24. Hence, the correct answer is option (C).
