A12.0-inch diameter turntable starts from rest and takes 2.00 s to reach its final rotation rate of 33.3 rpm. find: (a) the angular acceleration; (b) the number of revolutions completed in 5.00 s; (c) the time needed to complete 2.00 revolutions; (d) the radial and tangential accelerations of a point on the rim at 3.00 s.

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.

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.
