Sally measures that the number of groans per minute at 10.0°C is 12, and the number of groans per minute at 45.0°C is 31. If she measures that the number of groans per minute in the lizard's usual aquarium is 24, what is the temperature in the aquarium, in degrees Celcius? You can check your answer using the Mastering Physics assignment.

Question
Transcribed Image Text:Question 1: Sally's pet lizard makes a weird groaning noise every couple of seconds. She
notices that the number of groans per minute is very regular, but increases as the temperature
increases. Further observations reveal that the number of groans per minute actually has a
linear relationship with temperature over the normal range of temperatures in the lizard's
natural environment. So she decides to make use of her lizard as a thermometer.
Sally measures that the number of groans per minute at 10.0°C is 12, and the number of groans
per minute at 45.0°C is 31. If she measures that the number of groans per minute in the lizard's
usual aquarium is 24, what is the temperature in the aquarium, in degrees Celcius? You can
check your answer using the Mastering Physics assignment.
Math tip: A linear relationship between two quantities X and Y, means that for a change in X
(which we usually call AX), the change in Y is given by AY = m AX, where m is some constant. In
the range of X where this linear relationship exists, we can write Y = m X + b. If we graph Y vs X,
then m is the slope and b is y-intercept where the graph crosses the y axis.
