Two cars accelerate at a rate of 3 meters per second squared (m/s2). The mass of each car, in kilograms (kg), is shown in the chart below. How many more newtons (N) of force (kg X m/s2) are needed to accelerate the car with the larger mass?

My answer is opptionc, just check with anyone else

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.
