A. A traditional thermostat regulates temperature with the use of a bimetallic strip. The bimetallic strip consists
of Iron (a = 11.8 x 10-6 °C-4) and Copper (a = 16.5 x 10-6 °C'') that expand at different rates as the
temperature increases. Assuming that both metal strips are at 10 cm, find the difference in lengths between
the two metals as the temperature increases from 20°C (room temperature) to 100°C (boiling temperature).

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
