Acarnot engine absorbs 200 j of heat from a reservoir at the temperature of the normal boiling point of water and rejects heats to a reservoir at the temperature of the triple point of water. find the heat rejected the work done by the engine and the thermal efficiency.

What is the angular momentum of the bar about the axle?

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?
