As you look out of your dorm window, a flower pot suddenly falls past. the pot is visible for a time t, and the vertical length of your window is lw. take down to be the positive direction, so that downward velocities are positive and the acceleration due to gravity is the positive quantity g. assume that the flower pot was dropped by someone on the floor above you (rather than thrown downward). part a. from what height h above the bottom of your window was the flower pot dropped? part b. if the bottom of your window is a height h_b above the ground, what is the velocity v_{ground} of the pot as it hits the ground? you may introduce the new variable v_b, the speed at the bottom of the window, defined by

when it gains or loses electrons

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.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
