A car runs out of gas while driving down a hill. It rolls through the valley and starts up the other side. At the very bottom of the valley, which of the free-body diagrams in FIGURE Q8.2 is correct? The car is moving to the right, and drag and rolling friction are negligible.
Chapter 16: Temperature and Heat Heat: The energy transferred between objects because of a temperature difference o When the transfer of heat between objects in thermal contact ceases, they are in thermal equilibrium Zeroth law of thermodynamics: if object A is in thermal equilibrium with object B, and object C is also in thermal equilibrium with object B, then objects A and C will be in thermal equilibrium if brought into thermal contact Celsius scale: o Water freezes at 0 o Water boils at 100 Fahrenheit Scale: o Water freezes at 32 o Water boils at 212 Celsius Fahrenheit conversions The Kelvin scale is similar to the Celsius scale, except that the Kelvin scale has its zero at absolute z
