Answer:
2.25 %
Explanation:
65-95-99.7 is a rule to remember the precentages that lies around the mean.
at the range of mean (
) plus or minus one standard deviation (
),
at the range of mean plus or minus two standard deviation,
at the range of mean plus or minus three standard deviation,
So, note that they are asking about the probability that it is greater than 0.32, that is the mean (0.3) plus two times the standard deviation (0.1) (
)
So we know that the 95.5% is between
and
, hence approximately the 4.5% (100%-95.5%) is greater than 0.32 or less than 0.28. But half (4.5%/2=2.25%) is greater than 0.32 and the other half is less than 0.28.
So
E = hf, and h is the Planck's constant. When larger frequency is needed, more energy will also be needed. Since the blue light has the higher frequency, it would be the<span> level X to Y's transition which is the one that has the highest energy difference.

Answer:
fem = -A β
Explanation:
Faraday's law gives the induced electromotive source (emf)
fem = ![- \ \frac{d \phi_B }{dt}](https://tex.z-dn.net/?f=-%20%5C%20%5Cfrac%7Bd%20%5Cphi_B%20%7D%7Bdt%7D)
the magnetic flux is
= B. A = B A cos θ
the bold are vectros. In this case the normal to the ring is parallel to the magnetic field so the angle is zero cos 0 = 1, also the area of the ring is constant
fem = -A ![\frac{dB}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7BdB%7D%7Bdt%7D)
we carry out the derivative of the function B = α + β t
fem = -A β
so we see that there is an electromotive force in the ring.
