A dog sleigh driver prepared for her race. her sleigh was loaded with equipment, but on snow and ice, the dogs moved the heavy sled. Each dog pulled with a force of 600 N.
During the race, she came to an area of grass and dirt instead snow. The sled slowed to a stop.
The driver said, "There must be something wrong with one of the dogs. One of them is pulling with a force of less than 600 N.
How would you respond to the dog sled driver?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
