The phrase "a combination of gravity" is correct and usable in written English.
It can be used when discussing the effects or interactions involving gravity, often in scientific or metaphorical contexts.
Example: "The phenomenon observed in the experiment was a combination of gravity and electromagnetic forces acting together."
Alternatives: "an interplay of gravity" or "a blend of gravitational forces".
The monazite or xenotime is separated from the other minerals by a combination of gravity, electromagnetic, and electrostatic techniques, and then is cracked by either the acid process or the basic process.
The surface acceleration is 10−5 m/s2 due to a combination of gravity and centripetal acceleration.
The image, taken in October, reveals piles of debris at the cliff's base, suggesting that a combination of gravity and earthquakes caused landslides that created the cliff.
Secondly, Anandarao (1976) and Vineeth et al. (2007 20099) suggest that a combination of gravity wave tidal interactions, caused by enhanced planetary wave activity, is responsible.
However, based on the gravity separation results it can be seen that froth flotation was inefficient in the rejection of pyrite and so a combination of gravity and flotation techniques can consider to increase ash removal and produce clean products.
The undercarriage could also be lowered by a combination of gravity and a hand-pump.
Pipettes for patch-clamp recording are formed using only heat and gravity, while sharp electrodes for intracellular recording use a combination of heat, gravity, and a motor.
This reflects the rapidity with which the root develops in depth which is a combination of root gravity perception (or root angle) and growth rate (Al-Shugeairy et al. [2014]).
The empirical results indicate that a combination of Center of Gravity defuzzified Fuzzy Clustering and Pearson correlation coefficient can yield better recommendation results, compared to other techniques.
The two Mozambican dancers were a study in contrasts: Edivaldo Ernesto, long and lean, was ferocious in his attack (even when, or especially when, wearing a Phyllis Diller wig and full-length white lace gloves); Horacio Macuacua, short and solid, displayed an admirable combination of gravity and lightness.
Drying takes place by a combination of evaporation and gravity drainage through the sand.
