What is the specific heat capacity of a metal if it requires 176. 9 j to change the temperature of 15. 0 g of the metal from 25. 00°c to 32. 00°c?.

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.
