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).

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
