2. The common musk turtle, also called a %u201Cstinkpot%u201D, has a length of 7.85 cm at maturity. Suppose a turtle with this length is placed in front of a diverging lens that has a focal length of 14.0 cm. If the turtle%u2019s image is 4.00 cm across, how far is the turtle from the lens? How far is the turtle%u2019s image from the lens?
3. The body of the rare thread snake is as thin as a match, and the longest specimen ever found was only 118 mm long. If a thread snake of this length is placed a distance equal to four times its length from a diverging lens and the lens has a focal length of 216 mm, how long is the snake%u2019s image? How far from the lens is the image?
