A compound microscope consists of an objective lens of focal length f0 and an eyepiece that by itself produces an angular magnification 25.0
The microscope is designed so that the object to be viewed is on the left side of the objective lens and is focused in a plane that is 28.00 cm away from the right-hand (or inside) focal point of the objective lens. When properly adjusted, the eyepiece and the objective lens are 29.90 cm apart. The eyepiece magnification is based on an image at infinity and a near point at 25.0 cm. What is f0?
0.90 cm

An eagle, with a wingspread of 2.0 m, flies due North at 8.0 m/s in a region where the vertical component of the earth's magnetic field is 0.2 × 10-4 T
What emf would be developed between the eagle's wing tips? (It has been speculated that this phenomenon could play a role in the navigation of birds, but the effect is too small, in all likelihood.)
