A. the change in medium cannot affect the angle if the angle is perpendicular.
Rate of change = (amount of change) / (time for the change)
Amount of change = (temp at the end) minus (temp at the beginning)
Amount of change = (70°F) minus (62°F) = 8°F
Time for the change = (time at the end) minus (time at the beginning)
Time for the change = (1200 - 0800) = 4 hours
Rate of change = (8°F) / (4 hours)
Rate of change = 2°F per hour
Answer:
(D) 0.99 cm
Explanation:
Given that the radius of curvature of the mirror is 25 cm.
And another car is following which is behind the mirror of 20 m.

Focal length is half of the radius of curvature and it is negative for convex lens.
Now the mirror formula.

So,

Now
Magnification is,

So,

So, Height of the image

Therefore, the image height is 0.99 cm.
