Question: The mean time between collisions in iron is 5 × 10-15s.
Part A: What electron current is driven through a 1.8-mm-diameter iron wire by a 0.070V/m electric field?
Please show all work to solve the above question.
Steel expand 11 pars in million for each 1C change. think about the 1.3-km main span of steel for the Golden Bridge. if the span had no expansion joints, show that the span would be 0.21 m longer for a 15 C increase in temperature.
