You illuminate a metal with light of wavelength 630 nm and find that the photoelectrons have a maximum kinetic energy of 0.70 eV. You then illuminate the same metal with light of another wavelength and find a maximum kinetic energy of 2.6 eV for the photoelectrons. Required:
What is the second wavelength, in nanometers?

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
