I am not able to see the first question so I am solving the question no 2)
2) E = 4.50 * 10 ^ 5 Joule E1 = 2.60 * 10 ^ 6 Joule E2 = 7.00 * 10 ^ 6 Joule
dQ = dU + dw = 2.60 * 10 ^ 6 J - 7.00 * 10 ^ 6 J = - 4.40 * 10 ^ 6 J
dU = dQ - dw = - 4.40 * 10 ^ 6 J - 4.50 * 10 ^ 5 Joule
dU = -4.85 * 10 ^ 6 Joule ================================ANSWER)
