Can an object have kinetic energy if there is no motion.

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

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
