Chapter 1, Problem 30PCE
A Jiffy The American physical chemist Gilbert Newton Lewis (1875-1946) proposed a unit of time called the “jiffy." According to Lewis, 1 jiffy = the time it takes light to travel one centimeter. (a) If you perform a task in a jiffy, how much time has it taken in seconds? (b) How many jiffys are in one minute? (Use the fact that the

Using a single dimensional equation, estimate the number of steps it would take you, walking at your normal stride, to walk from the Earth to Alpha Centauri, a distance of 4.3 light-years. The speed of light is 1:86 x 105A miles/s.
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.
All the stars of the Big Dipper (part of the constellation Ursa Major) may appear to
be the same distance from the earth, but in fact they are very far from each other.

distances from the
earth to each of these
stars. The distances

- A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)?

- A surveyor measures the distance across a straight river by the following method: starting directly across from a tree on the opposite bank, he walks x = 1.00 102 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline lo the tree is = 35.0 (Fig. P1.53). How wide is the river? Figure P1.53arrow_forwardShow that, when SI units for 0 and 0 are entered, the units given by the right-hand side of the equation in the problem above are m/s.arrow_forwardIn SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .arrow_forward
