Halliday, Resnick & Walker β Measurement: Problem 45
(a) A unit of time sometimes used in microscopic physics is the shake. One shake equals \( 10^{-8} \) s. Are there more shakes in a second than there are seconds in a year? (b) Humans have existed for about \( 10^6 \) years, whereas the universe is about \( 10^{10} \) years old. If the age of the universe is defined as 1 "universe day," where a universe day consists of "universe seconds" as a normal day consists of normal seconds, how many universe seconds have humans existed?
π Solution Approach
Find: (a) A unit of time sometimes used in microscopic physics is the; (b) Humans have existed for about \
