If a ball is thrown straight up with a speed of 35 m/s. How high in meters will it reach above the point it was released. A) 22.1
B) 26.2
C) 19.8
D)17.1

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative. 

Iagree c would be the answer

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.
