Right studiot, the arrangement of the modern periodic table into groups and periods is both interesting as well as significant. Its significance lies in the fact that all elements down a group have same number of valence electrons and the elements across a period have same number of shells. In other words, the group number denotes number of valence electrons and period number represents the number of shells .
Relativity says that any massive body distorts or warps space-time. This distortion causes the attractive force of gravity.
Basically you can also say that you can attract any other massive body ( though your gravity will be tremendously small).
In the periodic table, all elements are arranged according to increasing atomic numbers of elements. And atomic number of an element is number of protons present.
Our psychology. It creates the distinction between humans, because a person of the lower strata may not seem as worthy as a person of higher class. This is how our inner mind works.
What is exactly religion ? Religion is a particular system of faith and worship followed by a group of people. It should be noted that religion, in its strict term, does not create groups, it is humans who create religions according to the needs of the groups.
Oh yes yes.... Good point swansont. I totally missed it out.
If [math]R[/math] is the radius of planet and [math]h[/math] is the distance of the object from the planet's surface and [math]S[/math] is the distance between their centres, then [math] S = R+h [/math]. Using this we get-
[math] h(R+h)^2 = \frac{1}{2}GMt^2 [/math]
