Auniform steel plate has an area of 0.897 m^2. when subjected to a temperature difference between its sides, a heat current of 27700 w is found to flow h it. what is the temperature gradient? what is the temperature difference when the plate is 0.0537 m thick? the thermal conductivity of steel is 50.2 w/(m k).

How will the system respond to a temperature increase?

What is the thinnest soap film (excluding the case of zero thickness) that appears black when illuminated with light with a wavelength of 480 ? the index of refraction of the film is 1.34, and there is air on both sides of the film. express your answer in nanometers. hint 1. how to approach th

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
