Agas has an initial volume of 15.4 l at a pressure of 1.5 atm and a temperature of 310 k. the pressure of the gas decreases to 0.9 atm as the temperature decreases to 268 k. what is the final volume of the gas? round your answer to the nearest tenth.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
