If the mass of a spaceship is approximately 5x10^9 kg, how much mass must be converted into kinetic energy to accelerate it from rest to one-tenth the speed of light? How much mass would be required to decelerate the spaceship to rest in space? Recall that there is no friction in space.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

spare some change and give it to the poor

explanation:

plz : ((

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.

cant without the picture! ?
