The universe has trillions of galaxies and counting. Astronomers give names to each galaxy base on its shape (e.i, Sombrero galaxy, Milkyway Galazy, ect,.).
Also, the size of the galaxy is taken into account and their color.
Answer:C..net work done on the object.
Explanation:
Answer:
The correct answer will be "
". The further explanation is given below.
Explanation:
The potential energy will be,
⇒ ![U(x)= -\frac{C_{6}}{x^6}](https://tex.z-dn.net/?f=U%28x%29%3D%20-%5Cfrac%7BC_%7B6%7D%7D%7Bx%5E6%7D)
The expression of force will be,
⇒ ![F=-\frac{dU(x)}{dx}](https://tex.z-dn.net/?f=F%3D-%5Cfrac%7BdU%28x%29%7D%7Bdx%7D)
⇒ ![=-(C_{6}(-6)x^{-7})](https://tex.z-dn.net/?f=%3D-%28C_%7B6%7D%28-6%29x%5E%7B-7%7D%29)
⇒ ![=-\frac{6C_{6}}{x^{7}}](https://tex.z-dn.net/?f=%3D-%5Cfrac%7B6C_%7B6%7D%7D%7Bx%5E%7B7%7D%7D)
Force seems to be appealing because the expression has been negative. It therefore means that the force or substance is acting laterally in on itself.
The measurement of the expansion of the universe was what gave rise to the big bang theory and it's predictions.
