An object is placed 10 m before a convex lens with focal length 4.8 m. Another concave
lens is placed 16.2 m behind the first lens with
a focal length –15 m (see the figure below).
Note: Make a ray diagram sketch in order
to check your numerical answer.
At what distance is the first image from the first lens
Answer in united of m
B. What is the magnification of the first image?
C. At what distance is the second image from the second lens?
Answer in units if m.
D. What is the magnification of the final image, when compared to the initial object ?

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
