An object with an acceleration of -10 m/s2 is
OA) speeding up 10 m/s every second
OB) slowing down 10 m/s every second
OC) moving at a constant speed of -10 m/s
OD) moving at a constant velocity of -10 m/s

can you give me more to work here with plzs and you

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
