Some writers believe that government-supported geophysical mapping initiatives and ocean satellite altitude systems such as Seasat may have a covert purpose to map mass concentrations and determine local Peacekeeper missiles.
32.
The more detailed models include ( among other things ) the bulging at the equator for the Earth, and irregular mass concentrations ( due to meteor impacts ) for the Moon.
33.
However useful the notion of a point mass may be in classical physics; in general relativity, such an idealized mass concentration into a single point of space is not even well-defined.
34.
As the science of geodesy measured Earth more accurately, the shape of the geoid was first found not to be a perfect sphere but to approximate an mass concentrations beneath Earth's surface.
35.
The properties that seem pertinent to lunar dust include : size distribution, mass concentration, particle surface area, number concentration, acidity, particle surface chemistry, particle reactivity, metal content, water solubility, and geometric form.
36.
The effect of lunar mass concentrations ( " masscons " ) on the orbit was found to be greater than initially predicted; over the course of the twenty-hour mission, the orbit was perturbated to by.
37.
The gathering this year is also unusual in that it is being described as an " open tribune "-- the government term used to describe the mass concentrations regularly held to press for Elian's return to Cuba.
38.
For a pure chemical the mass concentration equals its density ( mass divided by volume ); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.
39.
:Photoevaporation results when an extremely large star's radiation energy evaporates and literally blows away a protoplanetary disk ( a mass concentration of gas and dust ) in a process similar to that which forms a comet's tail.
40.
The gathering this year was also unusual in that it was being described as an " open tribune "-- the government term used to describe the mass concentrations regularly held to press for Elian's return to Cuba.
