Given the preceding result and the formula we derived in class for the heat produced during a completely inelastic collision (.e. such that the colliding objects end up sticking together), what should be the minimum value of the relative velocity of two snowballs, weighing at 1/2 lb each, so that they both melt as a result of a head-on collision? for simplicity, assume the snowballs are at zero degrees celsius. give answer in m/sec. (this problem will make you appreciate how much energy is stored at the molecular level, relative to the kinetic energy at macroscopic scales. the amount of energy stored in chemical bonds is even greater, which explains why we burn fuel to move heavy things around.)

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

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.
