What is the weight (in Newtons) of a 1 kilogram mass on Earth's surface? Find the density of the earth if its mass is 6 times 10^3 kg and radius is 6.4 times 10^3 km. The mass of the earth is 5.98 times 10^{24} kg. A satellite of ...
Detection of low energy neutral atoms (LENA's) produced by the interaction of the Earth's geocorona with ambient space plasma has been proposed as a technique to obtain global information about the magnetosphere. Recent instrumentation advances reported previously and in these proceedings provide an ...

According to a new "holy grail" scientific discovery, the blazing-hot ball of metal at the center of the Earth's core is actually more active than one might think. In fact, it might be host to a centra-planet molecular dinner party. ...
The chapter discusses neutral terrestrial atmosphere and the day and nighttime ionosphere. A detailed discussion on sources and sinks of hot oxygen and nitrogen atoms in the Earth's atmosphere is given. Thermalization of hot atoms in collision with ambient/bath gases is discussed taking into ...
The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw pictures of atoms, they show the electrons like satellites spinning round the Earth in orbits. ...
The atoms are1or2 \times 10^{-8}cm in radius. Now10^{-8}cm is called anangstrom(埃), so we say they are1or2angstroms (Å) in radius. Another way to remember their size is this:if an apple is magnified to the size of the earth, then the atoms in the apple are approximately...
The observable universe is the portion of the entire universe that we can potentially observe from Earth, given the finite speed of light and the age of the universe. It spans about 93 billion light-years in diameter. How do scientists estimate the number of atoms in the universe?
