Explanation:
a p e x test
A. because I had this question yesterday.
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.
Nice problem!
Look. At point A the road changes from a straight line to a circular line, then the motion changes from rectilinear to circular motion. So at that point, there is a sudden change in the acceleration, which for sure the passengers feel.
At point B, the circular motion changes from anticlockwise to clockwise, then there is another sudden change in the acceleration.
At point C, the road changes from circular to straihgt line, then the motion changes from rectilinear to circular, which produces a new sudeen change in acceleration.
Then the answeer is the last option, at points A, B and C.
11:C) sound travels fastest in solids
12:A) Sound needs a medium to travel
13:D) Just like with cupped hands
