An unknown material, m1 = 0.49 kg, at a temperature of t1 = 92 degrees c is added to a dewer (an insulated container) which contains m2 = 1.1 kg of water at t2 = 21 degrees c. water has a specific heat of cw = 4186 j/(kgâ‹…k). after the system comes to equilibrium the final temperature is t = 31 degrees c. detemine the specific heat of unknown material.

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?
