A body has velocity 30 m pr sec and acceleration is 10m pr sec square Wt will b the distance covered by a body in 1 sec??

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
