Air pressure is the weight of air on an area. The weight of air
is due to the gravitational forces between the Earth and the
molecules of its atmosphere.
The working distance gets shorter as the magnification gets bigger. In order to focus, the high-power objective lens must be significantly nearer to the specimen than the low-power lens. Magnification is negatively correlated with working distance.
Magnification change The magnification of a specimen is increased by switching from low power to high power. The magnification of an image is determined by multiplying the magnification of the objective lens by the magnification of the ocular lens, or eyepiece.
The geometry of the optical system connects the magnifying power, or how much the thing being observed seems expanded, and the field of view, or the size of the object that can be seen.

Answer:
C
Explanation:
If Ami is saying she likes it then it it personal. If you are speaking from statistics and studies it is impersonal and technically not from there perspective. All of these do this except C.
Answer:

Explanation:
Given
--- initial volume
--- initial temperature
--- final temperature
--- coefficient of thermal expansion:
Required
The change in volume
To do this, we make use of cubic expansivity formula

So, we have:



The volume will expand by 
I believe the answer would be B) ...... sorry if i'm wrong
