Textbook Question
Chapter 1, Problem 51P
The semiconductor chip at the heart of a personal computer is a square 4 mm on a side and contains 1010 electronic components.
- (a) What’s the size of each component, assuming they’re square?
- (b) If a calculation requires that electrical impulses traverse 104 components on the chip, each a million times, how many such calculations can the computer perform each second? (Hint: The maximum speed of an electrical impulse is about two-thirds the
speed of light .)

Assume your hair grows at a rate of 1/44th of an inch per day. How fast is that in nm/s (nanometers per second)?
Given that a typical atom is on the order of 1 x 10^(-10) m in diameter (see Table 1.3 on page 18 of the textbook), at approximately what rate does the protein synthesis
that assembles your hair strands deposit atoms in units of atoms per second?
I need the second question to be rounded to 1 significant digit.
In a situation in which data are known to three significant digits, we write 6.379 m = 6.38 m and 6.374 m = 6.37 m. When a number ends in 5, we arbitrarily choose to write 6.375 m = 6.38 m. We could equally well write 6.375 m = 6.37 m, “rounding down” instead of “rounding up,” because we would change the number 6.375 by equal increments in both cases. Now consider an order-of-magnitude estimate, in which factors of change rather than increments are important. We write 500 m ~ 103 m because 500 differs from 100 by a factor of 5 while it differs from 1 000 by only a factor of 2. We write 437 m ~ 103 m and 305 m ~ 102 m. What distance differs from 100 m and from 1 000 m by equal factors so that we could equally well choose to represent its order of magnitude as ~ 102 m or as ~ 103 m?
Consider the equation 4000/400 = 10.0. Assuming the number of significant figures in the answer is correct, what can you say about the number of significant figures in 4000 and 400?
