The coefficient of friction between tires and the road is about 1.0. At what angle should we bank our road if the average speed of cars driving on the road is 80 km/hr? (Don't forget to convert to m/s!) pls help omg im so confused

Your answer is 1.5 hope i

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.

Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object.
