Answer:
The percentage of legal quarters that will be rejected is 1.954 %.
Explanation:
Here we are required to find
P(X<5.48 or X>5.82)
We have μ = 5.67 and σ = 0.07 where the range is between 5.48 and 5.82 we each z-score given by
Therefore for 5.48 we have 
= -2.714
and for 5.82 we have 
= 2.143
Therefore we have the area of interest on the normal distribution chart given by
P(Z<-2.714) + P(Z > 2.143) = P(Z<-2.714) + (1 - P(Z < 2.143))
+ 0.00336 + 1 - 0.98382 = 0.01954
= 0.01954 × 100 = 1.954 %
Therefore 1.954 percentage of legal quarters will be rejected.
Answer with Explanation:
a.Intensity of radiation is directly proportional to the frequency of radiation
When the intensity of radiation increases then the frequency of radiation increases and therefore, the number of photo-electrons emitted by the metal increases.
b.When all of the wavelength in the radiation are increased by the same amount
We know that
Frequency is inversely proportional to the wavelength.
Therefore, the frequency decrease .
When the frequency decreases then the number of photo-electrons emitted by the metal decrease.
c.When the work function of the metal is increased then the gain of kinetic energy decreases .
When energy decreases then the number of photo-electrons emitted by the metal decreases.
