The gravity gradient ( variation with height ) above Earth's surface is about 3. 1 µGal per centimeter of height (), resulting in a maximum difference of about 2 Gal ( 0. 02 m / s < sup > 2 </ sup >) from the top of Mount Everest to sea level.

To do this variation, the body's center of gravity must be kept over the hands while performing the push-up by leaning forward while the legs are elevated in the air, which requires great strength and a high level of balance.

Ideally, a car should carry passengers and baggage near its center of gravity and have similar tire loading, camber angle and roll stiffness in front and back to minimise the variation in handling characteristics.

The gravity of a large satellite also stabilizes the planet's tilt ; without this effect the variation in tilt would be chaotic, probably making complex life forms on land impossible.

After working itself into more and more ecstatic heights culminating with the final variation, it suddenly goes through a surprising modulation to the original minor key, and the theme from the first movement returns with an even greater gravity, and the entire piece concludes with yet another death march.

Considerable variation in specific gravity is permissible, it having influence only on battery efficiency.

Theoretically he objected to Aristotle's ether, in its eternal uniformity, and argued that if one grants that the heavens must allow for a variation in composition then there's no reason to reject epicycles, while agreeing that equants and eccentrics, which violated Aristotelian principles of uniform circular motion and gravity, were impossible.

Unlike many other minerals, the specific gravity of diamond crystals ( 3. 52 ) has rather small variation from diamond to diamond.

This makes the surface gravity of the star non-uniform and causes temperature variation.

This effect is known as gravity darkening, because it results in a variation of radiation by latitude.

The value attempts to balance the rate of gain in genetic variation due to mutation with the rate of loss due to genetic drift.

It is vital to wind speed, because the greater the difference in pressure, the faster the wind flows ( from the high to low pressure ) to balance out the variation.

Though there is significant variation in length, balance, and weight of the jian from different periods, within any given period the general purpose of the jian is to be a multipurpose cut and thrust weapon capable of stabbing, as well as making both precise cuts and slashes, as opposed to specializing in one form of use.

This variation in the differential color output will change the color balance of the display and is much more noticeable than a decrease in overall luminance.

Prices for major cash crops are set in commodity markets with global scope, with some local variation ( termed as " basis ") based on freight costs and local supply and demand balance.

Fighters use this variation of the jab when they want to preserve the mobility and balance of their stance.

For use as the compensation balance he developed a slight variation of the invar alloy which had a negative quadratic coefficient of expansion.

A variation of the earlier invention, the Torsion balance, the Eötvös pendulum, designed by Hungarian Baron Loránd Eötvös, is a sensitive instrument for measuring the density of underlying rock strata.

A variation on the oldies theme is classic hits, which provides most of the playlist of oldies with some classic rock with an addition of contemporaneous R & B and pop hits as well, striking a balance between the mostly 1970s-focused classic rock genre and the more broad-based oldies format.

A variation of this error is omitting one of the ledger account totals from the trial balance.

The gender balance of this line-up enabled considerable variation in the dramatic setups for the sketches, in that all three men could be paired with either of the two women.

However, animals kept in constant environmental conditions also display such variation and this internal mechanism may be related to water balance regulation.

Tensho was created in 1921 as " softer sanchin " by Chojun Miyagi to balance Go aspect of Heishugata ( Sanchin-kata ) with Ju variation for Heishugata.

This variation between sites along environmental gradients reflects adaptive compromises by the species present to balance the need to capture light energy, manage heat gain and loss, while maximising the efficiency of gas exchange, transpiration and photosynthesis.

* An incline elevates the shoulders and lowers the pelvis as if reclining in a chair ; this variation emphasizes anterior deltoids and emphasizes the upper ( clavicular head ) of the pectoralis major.

The results of present observations of the thermal radio emission of the moon are consistent with the very low thermal conductivity of the surface layer which was derived from the variation in the infrared emission during eclipses ( e.g., Garstung, 1958 ).

that the amplitude of the variation was considerably less than the amplitude of the variation in the infrared emission as measured by Pettit and Nicholson ( 1930 ) and Pettit ( 1935 ) ; ;

-- Although there was some variation in results which must be attributed either to trace impurities or to variation in wall effects, the photochemical exchange in the gas phase was sufficiently reproducible so that it seemed meaningful to compare the reaction rates in different series of reaction tubes for the purpose of obtaining information on the effect of chlorine concentration and of carbon tetrachloride concentration on the reaction rate.

Ninety per cent of the 153 recorded impacts occurred between midnight and noon, and from day to day the variation of the rate was as much as an order of magnitude.

While nowadays we recognize the fact that there are many causes for bleeding at the nose, not long ago a nosebleed was simply that, and treatment had little variation.

Miss Xydis' earlier selections were Mendelssohn's Variations Serieuses, in which each variation was nicely set off from the others ; ;

The @ symbol was not used in continental Europe and the committee expected it would be replaced by an accented À in the French variation, so the @ was placed in position 40 < sub > hex </ sub > next to the letter A.

The Syriac script was a cursive variation of Aramaic.

* Customary acre-The customary acre was a measure of roughly similar size to the acre described above, but it was subject to considerable local variation similar to the variation found in carucates, virgates, bovates, nooks, and farundels.

Cod, in both fresh and salted form was enjoyed, with the salted variation created for long storage.

In the Middle Ages there was considerable variation in the methods of nomination of the Archbishop of Canterbury and other bishops.

Among Schoenberg's teaching was the idea that the unity of a musical composition depends upon all its aspects being derived from a single basic idea ; this idea was later known as developing variation.

Berg passed this on to his students, one of whom, Theodor Adorno, stated: " The main principle he conveyed was that of variation: everything was supposed to develop out of something else and yet be intrinsically different ".

A larger variation of the same design which Sakharov worked on was the 50MT Tsar Bomba of October 1961, which was the most powerful nuclear device ever exploded.
