In a manufacturing plant, aisi 1010 carbon steel strips (ρ = 7832 kg/m3) that are 2 mm thick and 3 cm wide are conveyed into a chamber at a constant speed to be cooled from 527ºc to 127°c. determine the speed of a steel strip being conveyed inside the chamber, if the rate of heat being removed from a steel strip inside the chamber is 119 kw.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
