Two lenses that are 35 cm apart are used to form an image. Lens 1 is diverging and has a focal length of f1= -7.0 cm; lens 2 is converging and has a focal length of f2 = 14 cm. The object is placed 24 cm to the left of lens 1.
A) Use a ray diagram to find the approximate location of the final image?
B) Is the final image upright or inverted? Is the final image real of virtual?
C) Determine the distance from lens 1 to the final image for this system?

An air traffic controller has two aircraft on radar. The first is at an altitude of 0.5 km, a horizontal distance of 3 km measured along the ground to the point directly underneath the plane, and a bearing of 115° west of north.
A copper telephone wire has essentially no sag between poles 20.5 meters apart on a winter day while the temperature is -15.5° C. How much longer is the wire on the summer day when the temperature is 27.0° C.
