When a metal was exposed to one photon of light at a frequency of 4.26× 1015 s–1, one electron was emitted with a kinetic energy of 5.00× 10–19 j. calculate the work function of this metal?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.

To a of 4 x hz is 1. 0. mm nm nm

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
