<h3><u>Answer;</u></h3>
Plano-convex lens
<h3><u>Explanation;</u></h3>
- Plano-convex lens has at least one plane surface
- <em><u>Plano-convex lenses are types of lenses that have one spherical surface and one flat surface. </u></em>
- These types of lenses are designed for infinite conjugate use or simple imaging in non-critical applications. The lenses are ideal for all-purpose focusing elements.
- For example; they are ideal for beam expansion, light projection, or for expanding an optical system's focal length.
Explanation:
It is known that the relation between speed and distance is as follows.
velocity =
As it is given that velocity is 6 m/s and distance traveled by the bear is (d + 29). Therefore, time taken by the bear is calculated as follows.
............. (1)
As the tourist is running in a car at a velocity of 4.2 m/s. Hence, time taken by the tourist is as follows.
............. (2)
Now, equation both equations (1) and (2) equal to each other we will calculate the value of d as follows.
=
4.2d + 121.8 = 6d
d =
= 67.66
Thus, we can conclude that the maximum possible value for d is 67.66.
