1.What is the photoelectric effect, and what experimental evidence led scientists to discover it? Does this support the wave or particle theory of light? Why? (3 points) 2. Explain why the wave model of light cannot explain the energy emissions from a blackbody radiator, but the particle model of light can. (3 points)

The slope of a velocity time graph over any interval of time gives the during that interval

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
