What factors affect the gravitational force between two object? Two primary things: The masses of the two objects in question, and The distance between them. Your answer would be 5.00e13
The chemical symbol of hydrogen is H. It is an element with atomic number 1, this means that 1 proton is found in the nucleus of hydrogen. Hydrogen is the lightest, simplest and most commonly found chemical element in the Universe, making up around 75% of its elemental mass. Hydrogen is found in large amounts in giant gas planets and stars, it plays a key role in powering stars through fusion reactions. Hydrogen is one of two important elements found in water (H 2 O). Each molecule of water is made up of two hydrogen atoms bonded to one oxygen atom. In 1766, during an acid metal reaction, Henry Cavendish first formally recognized hydrogen.
The most abundant gases found in our atmosphere are nitrogen and oxygen. Nitrogen makes up around 78% of the total atmosphere, while oxygen makes up 21%. The remaining 1% is made up mostly of a gas called argon.xygen is the most important of the gases in our atmosphere in relation to animal life. Almost all animals use oxygen as a critical ingredient for the processes of life. Without it, each of us and most of the animals on Earth would perish in a matter of just a few minutes.
