To solve this problem we will apply the concepts related to the calculation of the surface, volume and error through the differentiation of the formulas given for the calculation of these values in a circle. Our values given at the beginning are
The radius then would be
And
PART A ) For the Surface Area we have that,
Deriving we have that the change in the Area is equivalent to the maximum error, therefore
Maximum error:
The relative error is that between the value of the Area and the maximum error, therefore:
PART B) For the volume we repeat the same process but now with the formula for the calculation of the volume in a sphere, so
Therefore the Maximum Error would be,
Replacing the value for the radius
And the relative Error
Sitting = no movement
KE=0
Answer:
so this is nearly red colour light
Explanation:
As we know that the interference of light from reflected light then the path difference is given as
now we know that for constructive interference of light the path difference is given as
so we will have
so we will have
so this is nearly red colour light
