A 25 kg chair initially at rest on a horizontal floor requires a 365 N horizontal force

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

"induction" is the process of charging an object without touching it.hope my answer has you : )

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.
