Chapter 1, Problem 1.30E

A body occupies 150 ft3 and has a specific volume of 8 ft3/lbm. Assuming that g=32.2 ft/s2, calculate 1. a. mass b. density specific weight C. d. weight

7. What number should be reported to best reflect the temperature according to the thermometer? A. 21.7 °C B. 21.70 °C CC 22°C ........ 25 20 15 D. 21 °C 22.7°C E. undergo the

7. 12.0 mL of A weighs 10.8 g; and 16.0 mL of B weighs 14.4 g. A. A has a higher density than B. B. B has a higher density than A. C. A and B have equal densities. D. There is insufficient information to answer this question.

1. Which is higher: 85.7 °F or 28.9 °C ? 2. The boiling point of a liquid is calculated to be 325 K. What is this temperature on the Celsius and Fahrenheit scales?  3. The melting point of an unknown solid is determined to be 33.0°C. What is this temperature on the Fahrenheit and Kelvin scales?

6. Every morning I use 1 cup of Bisquick pancake mix to make pancakes for my kids. How many boxes of Bisquick do I use in 1 year? 7. How many meters per second (m/s) is a car moving if it is going 55 MPH? Hints: "MPH" is miles per hour or (miles/hour). A car that moves at 55 MPH is going 55 miles for every 1 hour, and the car travels 110 miles after 2 hours, 220 miles after 4 hours, etc. 110 miles 110 miles per hour = 55 miles per hour. 2 %3D Notice that the miles divided by time is 2 hours So, if a car is going 55 miles per hour, convert 55 miles into meters, convert 1 hour into seconds, and meters or then divide the answers to calculate meters per second (or nd second -).
