Question
Chapter 18, Problem 20A
(a)
To determine
Out of the elephant or mouse, the one which has more skin.
Expert Solution & Answer
Explanation of Solution
Introduction:
For larger animals, surface area is less compared with its weight. Smaller animals have large surface area for smaller weight.
The size of an elephant is larger than mouse. The surface area of elephant is larger than the surface area of mouse.
Conclusion:
Elephant has more skin than the mouse.

- When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture?
