Suppose that a hydrogen atom in the ground state absorbs a photon of wavelength 16.4 nm . if the atom is ionized, what will be the kinetic energy of the electron when it gets far away from its atom of origin? the value of ¯h is 1.05457 × 10−34 j · s ; the speed of light is 2.99799 × 108 m/s ; the value of h is 6.62607 × 10−34 j · s ; the rydberg constant for hydrogen is 1.09735 × 107 m−1 ; the bohr radius is 5.29177 × 10−11 m ; and the ground state energy for hydrogen 13.6057 ev . 1 ev = 1.60218 × 10−19 j . answer in units of ev.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

come closer and become far apart and become steam/gas

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
