spheres 1 and 2 both carry positive charge and are connected by insulating strings to a ceiling. when the two spheres hang in equilibrium, they hang at the same height, but sphere 1's string is more vertical. based on this observation, what can be assumed about the charges of the two spheres and why?

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.)

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

True or false graphs must include scales that increase by the same amount
