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?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
