You measure an electric field of 1.32×106 N/C at a distance of 0.165 m from a point charge. There is no other source of electric field in the region other than this point charge.

A)What is the electric flux through the surface of a sphere that has this charge at its center and that has radius 0.165 m?

B) What is the magnitude of the charge?

Efficiency is an action of doing something. for example when you take a test. good efficiency means you did well but bad effeciency or no effiency means you did bad.

Iam looking for this answer too!

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.
