Answer:
No
Explanation:
A planetary system consists of at least one star and non stellar objects revolving around it.
Our solar system has one star around which there are 8 planets. However there are star systems with more than one star. These systems are called binary systems. The size of stars also vary. They also vary by orbital configuration i.e, the planets have higher eccentricity than our solar system's. The planetary systems are also classified on the basis of the number of planets in them.
So, all planetary systems do not look the same as our own.
Answer:
The field of view is reduced.
Explanation:
Given that,
The field of view for every resultant magnification like you change objectives from 4 to 10 to 43.
We know that,
Field of view :
When the view is observed at a point in a defined field then these field called field of view.
The normal angle of field of view is 90°.
The formula of field of view is define as,

We can say that,
The field of view is inversely proportional to the magnification.
When magnification is low then field of view will be large.
When magnification is higher then field of view will be small .
According to question,
When the magnification adjust from 4 to 10 to 43, the field of view is reduced.
Hence, The field of view is reduced.
Answer: C). Light rays are bent by the water in the glass
It refracts the light
The bending of a light moving from one end to another is called refraction
Most directly on equador and least directly at poluses
Being the planet closest to the sun, Mercury must be the one
with the shortest year. That's how gravity works.
