<span>If two of the masses are at (0, 0) and (L, 0), by symmetry the x-coordinate of the third mass must be L/2, and then by the Pythagorean theorem its y-coordinate must be L(âš3)/2. Thus the position of the third mass is (L/2, L(âš3)/2).
Let each mass be m and C be the position of its center of mass.
Then C = (1/(3m)) (m(0, 0) + m(L, 0) + m(L/2, L(âš3)/2)).
= (1/3) (3L/2, L(âš3)/2).
= (L/2, L(âš3)/6).
That is, X_c = L/2 and Y_c = L(âš3)/6.</span>
The oldest lunar rock samples are approximately 4.4 billion years old and composed of anorthosite, a mineral that crystallizes and rises to the top of a lava ocean.
A certain amount of Conductivity
If light is traveling through a medium (i.e. air), the color of light depends on the wavelength.
The following are wavelength intervals of colors on the visible light spectrum. Measured in nanometers (nm).
Red: 700–635 nm
Orange: 635–590 nm
Yellow: 590–560 nm
Green: 560–520 nm
Blue: 490–450 nm
Violet: 450–400 nm
Answer is Weaker. If it is talking about the objects' gravitational forces.
