Two magnets are stuck together when a student pulls them apart and holds them close to each other so she can still feel them pulling on each other. How does pulling the magnets apart affect their magnetic potential energy?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Blank liquids and gases exert a buoyant force on objects placed in them
