Explanation:
The lens equation shows the relation among focal length of the lens, image distance and object distance. It can be expressed as:
=
+
where: f is the focal length of the lens, is the object distance to the lens and
is the image distance to the lens.
The lens equation can be used to determine the unknown value among the variables f , and
.
Answer:
The net displacement of the car is 3 km West
Explanation:
Please see the attached drawing to understand the car's trajectory: First in the East direction for 4 km (indicated by the green arrow that starts at the origin (zero), and stops at position 4 on the right (East).
Then from that position, it moves back towards the West going over its initial path, it goes through the origin and continues for 3 more km completing a moving to the West a total of 7 km. This is indicated in the drawing with an orange trace that end in position 3 to the left (West) of zero.
So, its NET displacement considered from the point of departure (origin at zero) to the final point where the trip ended, is 3 km to the west.
