All the other chices give evidence that supports that hypothesisthat the Moon was made of material that was flung off Earth during a time when it was rapidly spinning.
Explanation:
There is an enormous amount of similarities between the minerals in the moon rocks and the rocks on earth, except that for some minerals, like potassium, their quantities are higher on the earth than on the moon.
However, there is still supports for the evidence (by the other choices) that the moon was made from a piece of earth ejected from asteroid impact in primordial earth.Explanation:It’s believed that more than 3.5 billion years during the formation of earth and before it had cooled there were frequent asteroid impacts and one enormous collision ejected a large piece of molten earth into space but within earth’s gravity influence. This piece formed the moon. Evidence of asteroid impacts are frozen in time on the moon surface thanks to the fact that the moon has no atmosphere or tectonic plates movements that wipe off this ‘evidence’.

The magnitude of the force required to change the length of a spring-like object is directly proportional to the spring constant and the displacement of the spring. Elastic potential energy is directly proportional to the square of the change in length and the spring constant.
The answer is 1, 1 , 1 because that will balance out the equation and make them equal
Answer:
The wave's frequency is <u><em>733 hertz</em></u>.
Explanation:
The wavelength (λ) is the minimum distance between two points of the wave that are in the same state of vibration.
Frequency (f) is the number of vibrations that occur in a unit of time.
The speed of propagation (v) is the speed with which the wave propagates in the middle. Relate wavelength (λ) and frequency (f) inversely proportionally using the following equation: <em>v = f * λ</em>.
In this case you know that:
- Wavelength of the sound wave (λ) = 0.450 meters
- Speed of the sound wave (v)= 330 meters per second= 330
Replacing you get:
Then:
f=733.33 hertz≅733 hertz
Finally, <u><em>the wave's frequency is 733 hertz.</em></u>
I don't think so!!
Besides the fact that you're amazed at how cool the moon is.
