Answer:
Variance is
Solution:
As per the question:
Average value of the steam, = 25000 pounds per hour,
To calculate the variance, of the steam:
where
= standard deviation
at 0.8 is 1.285 from Z-table
Thus
Variance,
Answer:
0
-723.163841808 Wb
-350.282485876 Wb
Explanation:
= Permittivity of free space =
when r = 0.625 m the charges lie outside the sphere so q = 0
From Gauss law
The electric flux is 0
when r = 1.4
will be inside the sphere
The electric flux is -723.163841808 Wb
when r = 2.9 both charges lie inside the sphere
The electric flux is -350.282485876 Wb
