Chapter 25, Problem 1P
A single human cell encloses about 1.5 m of DNA. This length of DNA contains about 4.5 billion base pairs. What is the spacing between these base pairs in units of nanometers? That is, how far apart are the rungs on the DNA ladder? How many base pairs are there per millimeter?

Taking a Hike
A hiker begins a trip by first walking 21.0 km southeast from her car. She stops and sets up her tent for the night. On the second day, she walks 46.0 km in a direction 60.0° north of east, at which point she discovers a forest ranger's tower.

(a) Determine the components of the hiker's displacement for each day.
SOLUTION
Conceptualize We conceptualize the problem by drawing a sketch as in the figure. If we denote the displacement vectors on the first and second days by A and B, respectively, and use the ---Select-- as the origin of coordinates, we obtain the vectors shown in the figure. The sketch allows us to estimate the resultant vector as shown.
Categorize Drawing the resultant R, we can now categorize this problem as one we've solved before: --Select-- of two vectors. You should now have a hint of the power of categorization in that many new problems are very similar to problems we have already solved if we are…

It has been proposed to account for the apparent and uncanny fine tuning of our own universe. The idea of the multiverse is that there are infinite, distinct universes out there - all with distinct laws of nature and natural constants - and we live in just one of them. Using the accepted definition of the universe being all that there is (matter, space and energy), would you say that multiverse is a scientific theory?arrow_forward

Express your answer with the appropriate units. View Available Hint(s)for Part A Hint 1for Part A. How to approach the question The force the nurse applies to the syringe can be determined from the fluid pressure and the area of the plunger. The minimum force corresponds to the patient's lowest blood pressure.
