We are given with:
Q = 700 J
W = 400
U1 = 1200 J
From the first law of thermodynamics
Q = ΔU + W
Q = U2 - U1 + W
U2 = Q - W + U1
U2 = 700 - 400 + 1200
U2 = 1500 J
We are given with
Q = 500 J
W = 300 J
U1 = 1500 J
U2 = 500 - 300 + 1500
U2 = 1700 J
<span>the answer is 1) 1500 J, 2) 1700 J </span>

According to historical records, the Yuan dynasty, which lasted between 1271 and 1378 preceded the Ming dynasty which lasted between 1368 to 1644. Both the dynasties were based on a monarchy style of governance in which both lay more emphasis on issues of trade and cultural exchange.
As the 39th president of the United States, Jimmy Carter struggled to respond to formidable challenges, including a major energy crisis as well as high inflation and unemployment. In the foreign affairs arena, he reopened U.S. relations with China and made headway with efforts to broker peace in the historic Arab-Israeli conflict, but was damaged late in his term by a hostage crisis in Iran. Carter’s diagnosis of the nation’s “crisis of confidence” did little to boost his sagging popularity, and in 1980 he was soundly defeated in the general election by Ronald Reagan. Over the next decades, Carter built a distinguished career as a diplomat, humanitarian and author, pursuing conflict resolution in countries around the globe.
Historically speaking, cities tend to win because cities have a lot more man power, organized military, advanced tech, and unification. However, it is not all times that cities always won as they are also faced with adversaries that cannot be defeated even with the factors given above.
