During January, at a location in Alaska winds at-20°C can be observed, However, several meters below ground the temperature remains at 11°C. An inventor claims to have devised a power cycle working between these temperatures having a thermal efficiency of 10%. Investigate this claim. Part A What is the maximum thermal efficiency for these conditions? the tolerance is +/-2% By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor

Explanation:

Here Tmin= -20°c =253k

          Tmax= 11°c =284k

(A) maximum efficiency,

        ∩max= 1 - Tmin/ Tmax

                  =1-253/284 =0.10915

                     =10.915%

therefore his claim is true

answer:

All this is to say that new technologies develop quickly and continuously, and society is used to and adapts quickly to these constant innovations. ... Medical technology is always improving, leading to lower infant mortality, cures for diseases, and many more improvements in quality of life.
