Answer:
C ) 1.53
Explanation:
The critical angle of a material is given by the formula
where
c is the critical angle
n is the refractive index
This formula is valid if the second medium is air (which is the case of the problem).
In this problem, we know the critical angle:
Therefore we can rearrange the equation to find the refractive index:
Answer:
The maximum error is
Explanation:
From the question we are told that
The length is
The radius is
The pressure is
The rate is
The viscosity is
The error in the viscosity is mathematically represented as
Where
and
and
So
substituting values
