Because an alpha particle is the same as a helium-4 nucleus, which has mass number 4 and atomic number 2, this can also be written as:

Because of their relatively large mass, + 2 electric charge and relatively low velocity, alpha particles are very likely to interact with other atoms and lose their energy, so their forward motion is effectively stopped within a few centimeters of air.

Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation ; therefore, it is the most common window material for X-ray equipment and in particle physics experiments.

Because the FLRW metric assumes a uniform distribution of mass and energy, it applies to our Universe only on large scales — local concentrations of matter such as our galaxy are gravitationally bound and as such do not experience the large-scale expansion of space.

Because the stars in an open cluster are all at roughly the same distance from Earth, and were born at roughly the same time from the same raw material, the differences in apparent brightness among cluster members is due only to their mass.

Because of the increased mass, they usually employed ball bearings or roller bearings in the spindle to reduce friction and noise.

Because the stars were all born at roughly the same time, the different properties of all the stars in a cluster are a function only of mass, and so stellar evolution theories rely on observations of open and globular clusters.

Because the Moon's mass is a considerable fraction of that of the Earth ( about 1: 81 ), the two bodies can be regarded as a double planet system, rather than as a planet with a satellite.

Because this is a change to the observer's frame of reference ( i. e. the Earth itself ), it would therefore affect all stars equally.

Because any beryllium synthesized in stars is short-lived, it is a relatively rare element in both the universe and in the crust of the Earth.

Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as large-scale movement of air in the atmosphere or water in the ocean.

Because the orbital plane of the Moon is tilted with respect to the orbital plane of the Earth ( the ecliptic ), eclipses can occur only when the Moon is close to the intersection of these two planes ( the nodes ).

Because the majority of diversity and biomass on Earth is microbial, and thus difficult to measure, recorded extinction events affect the easily observed, biologically complex component of the biosphere rather than the total diversity and abundance of life.

Because the Earth is much heavier than the Moon, the barycenter is located within the Earth ( about below the surface ).

Because the Pacific plate is the largest of all the tectonic plates on Earth, crustal material at its western edge has had a long time since formation ( up to 170 million years ) to compact and become very dense ; hence its great height-difference relative to the higher-riding Mariana Plate, at the point where the Pacific Plate crust is subducted.

Because the discrepancy is not fully explained, uncertainty of our prediction of UT ( rotation angle of the Earth ) may be as large as the difference between these values: 11 s / cy < sup > 2 </ sup >.

Because so much biodiversity was lost, the recovery of life on Earth took significantly longer than after any other extinction event, possibly up to 10 million years.

Because they orbit the Sun on either side of the Earth's orbital path, some of them are, from time to time, 180 ° away from Earth.

Because right ascensions are measured in hours ( of rotation of the Earth ), they can be used

Because of this offset, a portion of the gravitational pull between Earth's tidal bulges and the Moon is perpendicular to the Earth – Moon line, i. e. there exists a torque between the Earth and the Moon.

Because of its debris disk, any planet orbiting Tau Ceti would face far more impact events than the Earth.

Because the " hallucinations " are so detailed and the captain refuses to admit he is not from Earth, Mr. Xxx, a psychiatrist, declares him incurable and kills him.

Because Triton's surface indicates a long history of melting, models of its interior posit that Triton is differentiated, like Earth, into a solid core, a mantle and a crust.

Because it is thought to be the most abundant mineral in Earth ’ s mantle at shallower depths, the properties of olivine have a dominant influence upon the rheology of that part of Earth and hence upon the solid flow that drives plate tectonics.

Because the weights will confine the compass's axis to be horizontal with respect to the Earth's surface, the axis can never align with the Earth's axis ( except on the Equator ) and must realign itself as the Earth rotates.

Because he was born in space, with one parent from Venus and the other from Earth, he claims Venusian citizenship ; more importantly, Sir Isaac vouches for him.

Because God is what He is, the laws of the universe, material and spiritual, are what they are.

Because of these involvements in the matter at stake, Boniface lacked the impartiality that is supposed to be an essential qualification for the position of arbiter, and in retrospect that would seem to be sufficient reason why the English embassies to the Curia proved so fruitless.

Because of the means of publication -- science-fiction magazines and cheap paperbacks -- and because dystopian science fiction is still appearing in quantity the full range and extent of this phenomenon can hardly be known, though one fact is evident: the science-fiction imagination has been immensely fertile in its extrapolations.

Because administration of the forest highway system is a responsibility of the Secretary of Commerce with maintenance provided by the States and counties, this Development Program for the National Forests does not include estimates of the funds needed to maintain the forest highway system nor to construct the additions to it that are needed.

Because the bobbin-to-cone winding process is a relatively high-cost operation for the mill, the almost complete automation provided by the Uniconer can mean important economies in textile production, at the same time upgrading quality.

Because of its importance, and because the lack of price competition is well recognized, the industry is under considerable public pressure not to raise its price any more than could be justified by cost increases.

Because community not severalty of property is the law of nature no man can assert an absolutely unalterable right to what is his.

Because of undesirable flavors, odors, colors, and generally low palatability associated with radiation treatment of this magnitude, the inactivation of enzymes is best accomplished prior to irradiation by the conventional heat-processing methods of blanching.

Because agricultural activities are seasonal and the areas of production and harvest of many foods are widely scattered geographically, and because of the high cost of transporting bulk food items any substantial distance to a central processing location, the use of large central processing stations, where low-cost radiation facilities approaching the megawatt range might be utilized, is inherently impracticable.

Because the rake angle Af at the tip of the knife is very much smaller ( or even negative ) when compared to the value of **yc for the major portion of the knife, a very rapid increase in cutting force with thickness will result.

-- Held out of Texas Tech's sweat-suits drill Monday at Lubbock was tackle Richard Stafford, who is undergoing treatment for a leg injury suffered in the Raiders' 38-7 loss to Texas A & M Because of its important game with Arkansas coming up Saturday, Baylor worked out in the rain Monday -- mud or no mud.

Because it is so large a state, with marked contrasts in population density, the organization of the New York co-operative offers a cross-section of how the plan works.

Because of this Dr. Bonnor holds that the universe is becoming more thinly populated by stars and whatever else is there.

Because all living beings possess a soul, great care and awareness is essential in one's actions.

Because anthropology developed from so many different enterprises ( see History of Anthropology ), including but not limited to fossil-hunting, exploring, documentary film-making, paleontology, primatology, antiquity dealings and curatorship, philology, etymology, genetics, regional analysis, ethnology, history, philosophy, and religious studies, it is difficult to characterize the entire field in a brief article, although attempts to write histories of the entire field have been made.

Because most embryonic development is outside the parental body, it is subject to many adaptations due to specific ecological circumstances.
