Answer:
When a magnet causes a paper clip to move, it's an example of Potential energy being changed in to Kinetic energy
A child running is an example of Kinetic energy
A motionless iron object in the magnetic field of a magnet may be said to have Potential energy
Answer:
2.74
Explanation:
Magnification = image distance/object distance
Mag = v/u
Given
v = 46cm
u = 16.8
Magnification = 46/16.8
Magnification = 2.74
Hence the magnification is 2.74
Answer:
c)by a factor of four
Explanation:
The total energy of a simple harmonic oscillator is given by
where
k is the spring constant of the oscillator
A is the amplitude of the motion
In this problem, the amplitude of the oscillator is doubled, so
A' = 2A
Therefore, the new total energy is
So, the total energy increases by a factor 4.

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.
