A100 w incandescent lightbulb emits about 5 w of visible light. (the other 95 w are emitted as infrared radiation or lost as heat to the surroundings.) the average wavelength of the visible light is about 600 nm, so make the simplifying assumption that all the light has this wavelength. how many visible-light photons does the bulb emit per second?

Which of the following is a source of heat for magma formation? magma plumes in the continental crust friction due to divergence friction due to subduction magma plumes in the oceanic crust

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
