Answer:
The weight is the gravitational force with which a body is attached to the Earth (planet/moon) Weight of any object on earth depends on two factors mass and gravitational constant. As per law, W = mg where, g is gravitational constant 9.8 m/s/s
1) The forces of molecules is how strong they are being held together. Now, we know that solid is the last one, because it's particles are held CLOSELY and VERY TIGHTLY together, which is why it has a definite shape.And last of all, a gas's particles are held freely, which is why it has no shape. So the answer would be:- gas, liquid, solid
3) The state of matter that does not have a definite shape, but has a definite volume is a liquid. So the answer is :- liquid
7) False, an endothermic reaction is when it absorbs energy, and as we know that in a chemical reaction as the following, it tends to be an exothermic reaction, meaning that is releases energy. So the answer is:- FALSE
8) Gases have particles that are far apart (freely) and move fast. So the answer is:- They are moving very fast and are far apart.<span> </span>

Answer:</h2>
(d) it is freely falling but it has a high tangential velocity.
<h2>
Explanation:</h2>
The Moon does not crash into the Earth because it is freely falling but it has a high tangential velocity, that is, actually the moon is falling toward the earth, but since it's moving so fast, then it will never hit the earth. The moon is so far away from the earth and move so fast that it falls around the earth in a continuous circular path. In other words, the high tangential velocity makes the moon to move around the earth. If the moon was moving slowly, gravity would make the moon to fall into the earth.
Answer:
Both of the stunt professionals will sustain injuries of the same seriousness
Explanation:
We are being told that both stunt professionals are standing from the same height, therefore they will attain the same equivalent speed at the bottom if we are to look at it from the principle of conservation of energy.
Now; According to principle of momentum; the momentum at which the first stunt professional A hits the ground be equal as the momentum with which stunt professional B will hit the wall.
Thus; both of the stunt professionals will sustain injuries of the same seriousness
Hello!! the answer should be C... I agree with the first person! I am taking this test too
