Jupiter subtends an angle of 1.67 10-4 rad when viewed by the unaided eye and 3.20 10-2 rad when viewed through an astronomical telescope that has a 0.043-m focal length eyepiece. Determine the focal length of the telescope's objective lens.

the answer is to check all of them! they all apply well at least i think so!

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
