A sheet of rubber and a sheet of cardboard and each 2 mm thick are pressed together and their order face are maintained at 0°C and 30°C. Find the temp of interface. Also calculate quantity of heat flows in one hour across a piece of rubber of air 100cm^2.[Kr=0.19WK^-1,Kcor=0.05]​

Which type of circuit is becoming more common in residential electrical design and construction? a. hazardous-area circuit b. three-phase circuit c. 480-volt circuit d. communication circuit

Which best represents the law of conservation of mass ?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
