B.) 100 N is the CORRECT answer
Please mark as brainliest! :)
The only thing we know of so far that can shift light to longer wavelengths is the "Doppler" effect. If the source and the observer are moving apart, then the observer sees wavelengths that are longer than they should be. If the source and the observer are moving toward each other, then the observer sees wavelengths that are shorter than they should be. It works for ANY wave ... sound, light, water etc. The trick is to know what the wavelength SHOULD be. If you know that, then you can tell whether you and the source are moving together or apart, and you can even tell how fast. If the lines in a star"s spectrum are at wavelengths that are too long, then from everything we know right now, the star and Earth are moving apart.
Answer:
There are six major nutrients: Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water.
Explanation:
We would need to know how long it took to do the work.
Power = (work) / (time).
The weight changes from place to place as the weight is a vector quantity as well as a dependent quantity. Therefore, weight seems to be varying but the inertia is not.
<u>Explanation:
</u>
The weight as already known well, is not a universal constant, whereas the mass is. As the weight is a product of mass of the body and the gravitational acceleration working on it, it varies as the factor of acceleration involved makes it a vector quantity.
And thus be dependent upon the direction too. Inertia of the body is an independent factor, on the other hand, an inherent property and so does not change.
