Electrically heated draw batch furnaces are commonly used in the heat treatment industry. consider a draw batch furnace front made of a 20-mm thick steel plate with a thermal conductivity of 11 w/m·k. the furnace is situated in a room with surrounding air temperature of 20°c and an average convection heat transfer coefficient of 10 w/m2·k. if the inside surface of the furnace front is subjected to uniform heat flux of 5 kw/m2 and the outer surface has an emissivity of 0.30, determine the inside surface temperature of the furnace front in k. (round your answer up to 2 decimal places.)

Why do electron microscopes have higher resolving power than light microscopes?

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
