The answer is C. A projectile is an object in motion from space that enters the earth’s atmosphere. When it gets to the earth, it is pulled by the force of earth's gravity. As it enters earth’s atmosphere, its inertia determines its path. The mass of the object determines its inertia. The more mass it has the higher its inertia which causes it to have a longer curvature when pulled by earth’s gravity.
Answer:
1) electron=19 Proton=19 Neutron=39-19=20
2) 1
3) in pic
C. 4.5 kilometers. This answer will represent 9 divided by a half which will be 4.5
This would be true.
The reason why this answer would be true is because a fossil's position in the rock layers determine how long they died and were preserved. If the fossils were right next to each other, then that means both organisms were preserved at the same time.
