For example, 7.9\ \times \ 10^{-2}\text{m} could be written either as 7.9 cm or 79 mm. (a) 7.59\ \times \ 10^{7}\text{m;} (b) 0.0074 m; (c) 8.8\ \times \ 10^{-11}\text{m;} (d) 1.63\ \times \ 10^{13}\text{m.}

A 4.0-kg particle moving along the _x_ -axis is acted upon by the force whose functional form appears below. The velocity of the particle at x = 0 is v = 6.0\ \text{m/s}. Find the particle’s speed at x = \left( \text{a} \right)2.0\ \text{m},\left( \text{b} \right)4.0\ \text{m},\left( \text{c} \right)10.0\ \text{m},\left( \text{d} \right) Does the particle turn around at some point and head back toward the origin? (e) Repeat part (d) if v = 2.0\ \text{m/s}\ \text{at}\ x = 0.

A city purchased five new firetrucks and apportioned them among the existing fire stations. Although your neighborhood fire station has the same proportion of the cityâs firetrucks as before the new ones were purchased, it now has one fewer. Is this scenario an example of a quota rule violation, the Alabama paradox, the population paradox, the new-states paradox, or none of these?

Interview a sample of 20 people who are not taking an astronomy class and ask them if they can name a living astronomer. What percentage of those interviewed were able to name one? Typically, the most publicly well-known living astronomer these days is Neil deGrasse Tyson. Why is he better known than most astronomers? How would your result have differed if you had asked the same people to name a movie star or a professional basketball player?
