The equation for the thermal efficiency of a system is given by n = Tc/Thx100
where n is the thermal efficiency, Tc is the temperature of the cold reservoir
and Th is the temperature of the hot reservoir. Dividing 190 by 515 gives us an
efficiency of 36.9%.
False. Agribusiness is agriculture conducted on a large, commercial scale.
Answer:
This is due to lactic acid accumulation in Emma's leg muscles.
Explanation:
In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.
This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.
