You are looking at yourself in a plane mirror, a distance of 3 meters from the mirror. your brain interprets what you are seeing in the mirror as being a person standing 6 meters from you.
<h3>Calculation</h3>
The plane mirror shows an exact replica of the real world. that means the distance of you from the mirror is the same distance as your reflection form the mirror at the opposite side of the mirror.
Thus, distance of image from the plane mirror is same as the distance of object (person) from the plane mirror but the image is formed behind the mirror.
Thereby we have v=u=3 m
Thus, distance between image and the person
is d = v + u = 3 + 3 = 6 m
Thus, the person is 6 meters away from the image.

The difference between a pure substance and a mixture is that mixtures are combinations of two or more pure substances, while pure substances cannot be separated into any other kinds of matter.
Answer:
Live training (whether through videoconference or a live course on a learning management system) or an eLearning course with knowledge checks is suggested so that learners can receive immediate feedback. Inclusion of a post-test – as well as an electronic guide describing jurisdiction-specific protocols – is strongly recommended.
Explanation:
From the given graph,
If the distance is on the y-axis and time is on the x-axis
Then in the given graph, curve A has a negative slope while curve C and line B has a positive slope. This proves that the behavior of x & y is inversely proportional to each other.
Now, from the graph, line drown from curve A will be inversely proportional to the line B.
Hence, the second option A will be the correct option.
