A car accelerates from rest to a velocity of 8 meters/second in 6 seconds. What is its average acceleration over this period of time?

1.33 m/s²

Explanation:

u = 0 ( starts from rest )

v = 8 m/s

t = 6 s

a = v - u / t

8 - 0/6

= 1.33 m/s²

momentum of soft ball three times less than baskey ball

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.
