Consider an air wedge that has distance between glass sheets of 0.70mm and a light that has a wavelength of 700nm shines on the glass plates. If we consider interference only between Rays 1 & 2 (as above) would we observe constructive or destructive interference (or neither)? How do you know?

She sold 135 peaches, because if you multiply 2.50 eith 135, you'd get 337.5, the 0 can be added or not.

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.
