It was by far "warm and wet growing seasons" that was the most important factor in terms of the South's economic development. Cotton and tobacco were the biggest exports.
Explanation:
These crops created tons of cash, had massive markets round the world, however required a stable and enormous hands to grow and harvest them.The yank South is understood for its long, hot summers, and wealthy soils in stream valleys creating it a perfect location for growing cotton. the various southern seaports and riverside docks allowed shipping cotton to remote destinations. By 1860, Southern plantations equipped seventy fifth of the world's cotton, with shipments from Houston, city, Charleston, Mobile, Savannah, and some different ports. The unquenchable European demand for cotton was a results of the commercial Revolution that created the machinery and factories to method raw cotton into vesture that was higher and cheaper than hand-made product.
0 Kelvin, also known as absolute zero, is equivalent to -273.15 degrees on the Celsius scale. Both scales are linearly related with the Kelvin scale starting at the lowest possible theoretical temperature.
The equivalent of 0 Kelvin on the Celsius scale is -273.15 °C. The Kelvin scale is an absolute temperature scale used commonly in science. This scale is based on absolute zero, which is theoretically the lowest possible temperature and is assigned the value of 0 Kelvin. This is the point at which there is no molecular motion and, therefore, no thermal energy. The Kelvin and Celsius scales are linearly related; one-degree change in temperature is the same on both scales. On the Celsius scale, which is defined with the freezing point of water at 0 degrees and the boiling point at 100 degrees, absolute zero or 0 Kelvin falls at -273.15 degrees Celsius.

Answer:
+60 kJ
Explanation:
Activation energy = PE(AB) - PE(A+B) = 100 -40 = +60 kJ
