(II) A projectile is fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a long flat
firing range. Determine (a) the maximum height reached
by the projectile, (b) the total time in the air, (c) the total
horizontal distance covered (that is, the range), and (d) the
speed of the projectile 1.50 s after firing.

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for

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.
