Ask your teacher the same force that gives the standard 1 kg mass an acceleration of 1.00 m/s2 acts first on body a, producing an acceleration of 0.530 m/s2, and then on body b, producing an acceleration of 0.352 m/s2. find the acceleration produced when a and b are attached and the same force is applied.

The lid of a pressure cooker forms a nearly airtight seal. steam builds up pressure and increases temperature within the pressure cooker so that food cooks faster than it does in an ordinary pot. the system is defined as the pressure cooker and the water and steam within it. if 2.0 g of water is sealed in a pressure cooker and then vaporized by heating, and 5127 j must be added as heat to completely vaporize the water, what is the change in the system’s internal energy? answer in units of j.
