Correct option is
C
3 cm
RI=apparent depthreal depth
Substituting, 34=apparentdepth12
Therefore, apparent depth=412×3=9
The height by which it appears to be raised is 12−9=3cm

A tank is filled with water to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again?
Answer:
In the beginning, I was not familiar to assess assessments of the other students. Ifelt a little bit weird that is it possible to check assignments while having an instructor.I was also a bit frustrated, to be honest, that why do we have to assess thoseassessments. It was kind of extra burden for me. But after few weeks assessingmore assignments, my feeling had changed because I was learning lots of thingsthat were changing my perspectives. I was gaining extra knowledge from my peersin the form of assessments. Yes, I am comfortable with assessing assessments,because I got to learn many vocabularies and making structures of the sentencecorrectly by improving grammatically as I am not a native English speaker. Thus, inthis way, I was learning something new in each and every assessment.

Answer:
a )
Density = mass / volume
= 3500 / 3.5
= 1000 kg m⁻³
b) gauge pressure = h d g
h is height of water column
d is density
g is acceleration due to gravity
Put the values in the equation above
Gauge pressure = .15 x 1000 x 9.8
= 1470 Nm⁻²
Atmospheric pressure = 100000 Nm⁻²
Total pressure
= 101470 N m⁻²
c ) Volume of water displaced = volume of object
= 55 x 10⁻⁶ m³
Buoyant Force = weight of displaced water
= 55 x 10⁻⁶ x 1000 x 9.8
= .539 N.
