15. Thermometers. There are two scales in common use to measure the tem- perature, called Fahrenheit degrees and Celsius degrees. Let F and C, re- spectively, be the temperature on each of these scales. Each of these quanti- ties is a linear function of the other; the relation between them is determined by the following table: physical measurement C F freezing point of water 0 32 boiling point of water 100 212 a) Which represents a larger change in temperature, a Celsius degree or a Fahrenheit degree? b) How many Fahrenheit degrees does it take to make the temperature go up one Celsius degree? How many Celsius degrees does it take to make it go up one Fahrenheit degree? c) What is the multiplier m in the equation AF = mAC? What is the multiplier u in the equation AC = AF? (The symbol u is the Greek letter mu.) What is the relation between u and m
