Problem 57

A 230 kg crate hangs from the end of a rope of length L = 12.0 m. You push horizontally on the crate with a varying force F to move it distance d = r 4.00 m to the side (Fig. 7-43). (a) What is the magnitude of F when the crate is in this final position? During the crate's L displacement, what are (b) the total work done on it, (c) the work done by the gravitational force on the crate, and (d) the work done by the pull on the crate from the rope? (e) Knowing F that the crate is motionless before and after its displacement, use the answers to (b), (c), and (d) to find the work your force F does on the crate. (f) Why is the work of your force not equal to the product of the horizontal displacement and the answerto (a)?

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
