Define the billiard ball and the edge of the pool table as the components of the system shown in Figure 5. Is it an isolated system? Is the total momentum of the system conserved after a collision of the billiard ball and the edge of the pool table?

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

Work = force × a. work b. energy c. distance d. momentum
