Connor leaves from his house at position x = 0 m to walk to the store at position x = 150 m. After visiting the store, Connor walks to his friend’s house at position x = -30 m. a. Did Connor pass his house on his way to his friend’s house?
b. What was the distance traveled by Connor on his walk?
c. What was Connor’s displacement on his walk?

Wish i knew this to !

Ibelieve that the correct answer is: c. along plate boundaries

Ithink it’s: light bounce if off a mirror

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.
