The Gulf Stream, for example, has an average speed of 4 mph, or 100 miles/day, or 3600 miles/year, in round numbers. A complete circuit around the Atlantic is 8 or 10 thousand miles, which would take around 3 years on a raft.

**Answer:**

**Image distance of apple=-6.7 cm**

**Magnification of apple=0.33**

**Explanation:**

We are given that an apple is placed 20.cm in front of a diverging lens.

Object distance=u=-20 cm

Focal length=f=-10 cm

Because focal length of diverging lens is negative.

We have to find the image distance and magnification of the apple.

Lens formula

Substitute the values then we get

**Image distance of apple=-6.7 cm**

Magnification=m=

Magnification of apple=

**Hence, the magnification of apple=0.33**

Is there a multiple choice?
