The Stanford Linear Accelerator Contains Hundreds of Brass Disks Tightly $\degree$

question 14

Multiple Choice

The Stanford linear accelerator contains hundreds of brass disks tightly fitted into a steel tube (see figure) . The coefficient of linear expansion of the brass is 2.00 *10^-5 per C $\degree$ .

If the diameter of a disk is 80.00 mm at 43 $\degree$ C, what is its diameter in the dry ice?

• A) 78.40 mm
• B) 79.68 mm
• C) 80.16 mm
