Asmall metal bead, labeled a, has a charge of 28 nc . it is touched to metal bead b, initially neutral, so that the two beads share the 28 nc charge, but not necessarily equally. when the two beads are then placed 5.0 cm apart, the force between them is 4.4×10−4 n . assume that a has a greater charge. what is the charge qa and qb on the beads?

small = small current large mag large current

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.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
