Photoelectrons with a maximum speed of 8.00 _ 106 m/s are ejected from a surface in the presence of light with a frequency of 6.32 _ 1014Hz. If the mass of an electron is 9.10 _ 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.64 x 10-24 J
2.88 x 10-16 J
5.82 x 10-17 J
2.91 x 10-17 J

correct it is c.) b b

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
