Answer:
OPTION D (The waves will sometimes get very high and very low) is the answer.
Explanation:
Wavelength = velocity ÷ frequency
As the frequency which measures the number of waves per unit of time is inversely proportional to the wavelength, point X which lies between two sources, and one source is shorter than another, the wave heights at point x will vary as the distances from point X vary too. This means that waves at point X depending on the wave type and source will get very high at times and very low.
A.) Electrons are Shared in a covalent bond.
Answer: The correct answer is option(B.).
Explanation:
The co-formation theory explain that both moon and the earth are formed at same time from the primitive solar nebula (cloud made up of dust and gases) at the same and same place.
Where as capture theory suggests that the moon is an asteroid which was formed or created somewhere else in a solar system. And when the moon approached the earth planet it got captured by the earth's gravitational field.
Impact theory explains the formation of moon by the catastrophic collision between the earth and any planet half the size of earth's size.
Synchronous theory sheds the light on the rotation time, revolution time and sides of moon located from the surface of the earth.
Hence, the correct answer is option(B).
