A point charge has q=1.0×10-6 coul. Consider point A 2.0 meters distant and
point B 1.0 meter distant from the charge.
i) If point A is on east side of the charge and point B on west side of the
charge, what is the potential difference VA-VB? Draw a diagram of the
arrangement.

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.
