Points a (2. 0 m, 2. 1 m) and b (5. 7 m, 7. 0 m) are located in a region where the electric field is uniform and is given by e = 3i 4j (n/c). What is potential difference (va-vb).

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
