Answer:
Explanation:
The maximum efficient power plant will be the plant based on carnot cycle whose efficiency is given by the following formula
Efficiency = (T₁ - T₂) / T₁
T₁ is temperature of hot reservoir and T₂ is temperature of cold reservoir.
Putting the given values
efficiency of power plant = (35 - 5) / (273 + 35 )
= 30 / 308
= .097
= 9.7 %
Answer:
This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age. By 2000 the population counted 6 billion heads, however, population growth (doubling time) started to decline after 1965 because of decreasing birth rates.
