Using the image above, an object is traveling to the left. Compared to the wave frequency and wavelength on the right, as the wave moves left there is a A. lower frequency and shorter wavelength
B. lower frequency and longer wavelength
C. higher frequency and longer wavelength
E. higher frequency and shorter wavelength​

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
