When the wave meets the condition of interference occurs. The interference effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.
Hence the phenomenon of interference occurs when two wave pulses are traveling along a string toward each other.
One wave on a string is moving toward the right and another is moving toward the left. When they meet in the middle, half of the cycle of the wave from the right overlaps with half of the cycle of the wave from the left.
The result is that the string gets flat when the two waves meet the condition of the interference of wave occurs.
Hence when the wave meets the condition of interference occurs.

According to Newton's Law of Gravity, if two objects were to move twice as far apart, the force of gravity between them would be...
The force of gravity between them given the data from the question, would decrease by a factor of 4
Newton's law of gravityF = GM₁M₂ / r²
Where
F is the force G is the gravitational constant M₁ and M₂ are the masses of the objectsr is the distance apart Data obtained from the question Initial distance apart (r₁) = rInitial force (F₁) = FFinal distance apart (r₂) = 2rFinal force (F₂) =? How to determine the final forceF = GM₁M₂ / r²
Cross multiply
Fr² = GM₁M₂
GM₁M₂ = constant
F₁r₁² = F₂r₂²
With the above formula, we can obtain the final force as follow:
F₁r₁² = F₂r₂²
F × r² = F₂ × (2r)²
Fr² = F₂ × 4r²
Divide both side by 4r²
F₂ = Fr² / 4r²
F₂ = F / 4
Thus, we can conclude that the final force will decrease by a factor of 4

Earth has a definite orbit within the solar system whose the orbit is mainly a result of the mass of the Sun.
What is an orbit?An orbit is defined as the regular, repeating path that one object in space takes around another while an object in an orbit is called a satellite which may be natural, such as the Earth or the Moon. According to the height of satellites from the earth, these orbit are classified as
High Earth orbitMedium Earth orbitLow Earth orbit.Most of the weather and some communications satellites will tend to have a high Earth orbit which is farthest away from the surface. The main difference between orbit and orbitals is that the former is defined as a fixed path of electron revolutions, whereas the latter is defined as an uncertain region with a high probability of finding an electron.
Therefore, the Earth has a definite orbit within the solar system whose the orbit is mainly a result of the mass of the Sun.
