- A study finds that the metabolic rate of mammals is proportional to m3/4, where m is the total body mass. By what factor does the metabolic rate of a 70.0-kg human exceed that of a 3.98-kg cat?A student measures the mass of an object with a scale several times, resulting in an average mass m = 11.29 grams. Another student points out that the scale was not “zeroed”, or calibrated to read zero mass with no object on it, before the object was weighed. Without a load, the scale reads 0.08 grams. No one has used the scale since the last measurement. c) What is the correct mass of the object?Q23. The width of a man's hand was used as a common unit of length several hundred years ago. What are the advantages and disadvantages of using such a unit? Explain. E1. Suppose that a pancake recipe designed to feed three people calls for 600 mL of flour.

- Small animals eat much more food per kilogram of body mass than do larger animals. The basal metabolic rate (BMR) is the minimal energy intake necessary to sustain life in a state of complete inactivity. The table lists the BMR in kilocalories per day, the mass, and the surface area for 4 animals. What is the BMR per square meter of the surface area for the mouse?The speed of sound is 1100 ft/sec at sea level. a. Express the speed of sound in mi/hr. b. Change the speed of sound to mi/year. Let 365 days=1 year.The Statue of Liberty in New York City is approximately 305 ft305 ft tall. How many U.S. dimes would be in a stack of the same height?
