Concept explainers
As a contrast between the old and the modern and between the large and the small, consider the following: In old rural England 1 hide (between 100 and 120 acres) was the area of land needed to sustain one family with a single plough for one year. (An area of 1 acre is equal to 4047 m2.) Also, 1 wapentake was the area of land needed by 100 such families. In quantum physics, the cross-sectional area of a nucleus (defined in terms of the chance of a particle hitting and being absorbed by it) is measured in units of barns, where 1 barn is 1 × 10-28 m2.

- In 2011, artist Hans-Peter Feldmann covered the walls of a gallery at the New York Guggenheim Museum with 100,000 one-dollar bills (Fig. P1.48). Approximately how much would it cost you to wallpaper your room in one-dollar bills, assuming the bills do not overlap? Consider the cost of the bills alone, not other supplies or labor costs. FIGURE P1.48arrow_forwardFigure P1.6 shows a frustum of a cone. Match each of the three expressions (a) (r1 + r2)[h2 + (r2 r1)2]1/2, (b) 2(r1 + r2), and (c) h(r12 + r1r2 + r22)/3 with the quantity it describes: (d) the total circumference of the flat circular faces, (e) the volume, or (f) the area of the curved surface. Figure P1.6arrow_forwardIf you used only a keyboard to enter data, how many years would it take to fill up the hard drive in your computer that can store 95gigabytes95gigabytes (95×109bytes95×109bytes) of data? Assume "normal" eight-hour working days, and that one byte is required to store one keyboard character, and that you can type 180 characters per minute. Express your answer using two significant figures.arrow_forward
- A contractor wants to install ceramic tile in a kitchen of length 9.13 m and width 6.2 m. What is the area of the room (in m2)? Express your answer using the proper number of significant figures.arrow_forwardCalculate the approximate number of board feet (one board foot is defined as a volume of 1 in x 1 ft x 1 ft) of lumber that would be available in a log that has a diameter of 26 cm and a length of 2.4 m. Assume the log is a right cylinder and that the saw mill must make the log into a rectangular prism before cutting it into boards.arrow_forward(a) A pyramid has a height of 478 ft and its base covers an area of 15.0 acres (see figure below). The volume of a pyramid is given by the expression V = where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = 43,560 ft2) m3 (b) What If? If the height of the pyramid were increased to 522 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase? %arrow_forward
- a) A pyramid has a height of 484 ft and its base covers an area of 11.0 acres (see figure below). The volume of a pyramid is given by the expression V = where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = 43,560 ft2) 2.19*10**6 m3 b) What If? If the height of the pyramid were increased to 519 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of th pyramid increase?
