Raziel walks 3 m north, 5 m east, 3 m south, and 5 m west. What is Raziel's total displacement from his original position? (Include the unit)​

Ithink the answers is a i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

The answer is 12, for the points

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.

The anwser is: wave a has a greater pitch and frequency.
