Textbook Question
Chapter 1, Problem 45P
(a) A unit of time sometimes used in microscopic physics is the shake. One shake equals 10−8s. Are there more shakes in a second than there are seconds in a year? (b) Humans have existed for about 106 years, whereas the universe is about 1010 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?

On the planet Zebulon, the standard unit for length is the clorf (cl) and the standard unit for time is the beedle (be). After many years of research, you have determined that 1clort = 0.765 meters 1beedle = 1.957 seconds (1cl = 0.765m) (1be = 1.957s) If you are driving at a speed of 85mi / h , how fast are you going in terms of clorés per beedle (cl/be)? NOTE: 1 mi = 1609 m.
The distance around the Earth's equator is 40,077 kilometers, and the population of the United States
in 1,950 was approximately 150,000,000 people. If this many people were spaced equally around the
equator, what would be the length of the space each person would have to the nearest centimeter?
The approximate length the space would be
cm.
We are going to make a simple approximation of the number of atoms in the universe.
Assume all the atoms in the universe are hydrogen. (In actual practice, over 75% of the atoms in the universe are hydrogen.)
Assume the sun is a typical star (made of pure hydrogen) has a density of 1.4 g/cm3 and is a sphere with a radius of 7.0*108m
Assume that there are 100 billion stars in our Milky Way galaxy that are identical to our sun.
Assume that there are 10 billion galaxies in the universe identical to our Milky Way galaxy. How many atoms are there in the universe?

- A biologist studies a species of bacteria called FAST, her research reveals that FAST bacteria reproduced prodigiously. If a bacteria culture contains 10 FAST bacteria at time t= 0, the number of FAST bacteria in the culture later time 't' is N(t) = 10 +6t +2t2 where 't' is expressed in seconds. How many bacteria occupy the culture a time t = 10s? At t =11s? Calculate how many net bacteria were born during the interval between t=10 and t=11, assume no bacteria died. Now use calculus to find the birth rate of bacteria (rate at which new bacteria get born) at time t=10s, it may help to sketch a rouch graphy of N vs 't'.arrow_forwardA typical person has an average heart rate of 71.0 beats/min.
