Well let see, we don't have any information about the initial distance we have to use our logic
assuming that the distance moves from 1 to 2 m with initial speed , it means that the distance factor is 2
Since the initial speed has doubled, it would be very likely that the factor of the distance is MORE THAN 2 . Find the answer that either got 3 or 4 distance factor
hope this helps
The source of the earth's magnetic field is found in the ;LIQUID MAGNETIZED IRON IN THE CORE OF THE EARTH. The earth's magnetic field is believed to be generated very deep down in the earth's core as a result of molten iron which it contains.
The sound produced by an instrument of length L that is open at one end
usually has a high frequency.
<h3>What is Sound?</h3>
This is a form of vibration which travels along an acoustic wave through a
media which could be solid, liquid etc.
Sopubd produced by an instrument which has an open end has a high
frequency and pitch, nodes , timbre and a low antinode. These are all the
properties of sounds by the instrument.

The concept of a black hole seem reasonable to me because of its valid and authentic evidences.
<h3>What are the causes, characteristics, and major features of black holes?</h3>
A black hole is a region in space where light is unable to escape due to strong gravitation force. The strong gravity is formed because matter has been pressed into a tiny space. This compression occurs at the end of a star's life. Some black holes are formed when a stars die.
So we can conclude that the concept of a black hole seem reasonable to me because of its valid and authentic evidences.

Waves: can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
A wave refers to a disturbance in a medium that progressively transports energy from its source to another location, without transporting matter.
In Physics, there are two main (2) types of wave and these are;
- <u>Mechanical waves:</u> an example is sound wave, which requires a medium for its propagation.
- <u>Electromagnetic waves:</u> an example is light wave, which doesn't require a medium for its propagation and can travel through a vacuum or an empty space.
Basically, some of the phenomenon associated with waves include the following:
I. Doppler shift (Doppler effect).
II. Reflection.
III. Refraction.
IV. Diffraction.
V. Constructive interference.
VI. Destructive interference.
In conclusion, all waveform can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
