I’m a bit confused on your question but i believe you’re asking to define uniform velocity, which is the condition which a body covers equal distance in an equal interval of the time is known as uniform velocity. an example would be when a truck travels in equal distances in equal intervals of time then we say the body has a uniform velocity
an amorphous solid is a solid that lacks the long-range order
Answer:
Her answer is not reliable.
Explanation:
Reliability and validity are two major concepts that are used to assess the standard and quality of response/research.
While validity of an instrument is the idea that the instrument measures what it intends to measure, reliability is all about consistency and whether or not results could be replicated.
While your friend's answer may be valid, it can't reliable because of the differences in her response within a short time.
The direction changes but not the speed.
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.
