Answer:
Since you haven't provided any choices, then the answer is "Free Fall Motion."
Explanation:
In order to learn more about the answer, let's discuss what free fall motion is.
Free Fall- In Physics, this refers to any body motion that is acted upon solely by <u>"gravity."</u> The acceleration in free fall is always downward and there's the absence of other forces. Take note that the<em> acceleration should be the same and is independent of the object's mass. </em>This acceleration is called "acceleration due to gravity."
Gravity- This refers to the force that pulls any object towards the center of the earth.
<u>Examples of Objects in Free Fall Motion</u>
1. A ball dropped at the top of a building.
2. Dropping a coin from a table.
The ball and the coin are both in free fall motion because they are being pulled by gravity towards the earth. Their acceleration is also constant and there are no other forces acting upon them.
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
The vectors must point in the same direction.
Friction and the applied force are not balanced. The 7 N push is countered by the frictional force of 3 N to push the box with a net force of 4 N.
Answer:
Question 5: The outer core has a lower temperature and lower pressure than the inner core
This is because the outer core is not as hot as the inner core. It is also under slightly less pressure. Due to this, the outer core is liquid and less dense than the inner core.
Question 6: I'm not sure what the answer to that is.. but I believe you'll figure it out!
