In the Bermuda Rise seismic velocities in the oceanic crust differ somewhat from the typical abyssal-floor values.
Variation with depth in shallow and deep water marine sediments of porosity, density and the velocities of compressional and shear waves: Geophysics, v.
The crustal structure of oceanic rises differs significantly from the typical abyssal floor in having lower velocities and generally thicker crustal layers.
That the friction at the higher velocities occurring in engineering practice is much less than at common velocities has been shown by several modern experiments, such as those of Sir Douglas Galton (see Report Brit.
For many practical purposes these statements are sufficiently accurate, and they do in fact sensibly represent the results of experiment for the pressures and at the velocities most commonly occurring.
The velocities stated in the table will be obtained when the pulley a', fig.
This is effected by giving different velocities to the pulley on the axle of the conical drum s, corresponding with e.
The wheel of the second or delivery fluted roller is seen to be smaller than that of the first, by which means the difference of their velocities is obtained.
The spectroscope also makes it possible to measure the velocities of objects which are approaching or receding from us.
But of these two velocities that of the satellite may be taken as sensibly invariable, when close enough to use his pencil.
To account for all the lines mapped by Lowell some of them must have been produced by satellities moving relatively to the surface of Mars at velocities so great 187 as three miles a second or even rather more.
Is it not evident, then, I ask you, that there will some day appear velocities far greater than these, of which light or electricity will probably be the mechanical agent?
It would be necessary to go further and prove that large and small payments bear a constant ratio to one another, and further, that velocities of money and of bank-deposits employed in these ways bear a constant relation.
As a matter of fact, the velocities of circulation of money and deposits depend, as we have seen, on technical conditions, and bear no discoverable relation to the quantity of money in circulation.
If anyone is particularly anxious about the equation of exchange in this process, he may add to my expansion of credit an increase in velocities to keep it straight!
Custom and habit could not possibly regulate things so complex as velocities of money and bank-deposits.
Then, if the equation of exchange is to be maintained, either M or M' or their velocities must be increased, or trade must be reduced.
Is it true that while change may occur from causes outside the equation of exchange in volume of money, volume of trade, and velocities of circulation, a change in the price-level from causes outside the equation is impossible?
The experiments made with the experimental cradle distinctly showed that any rule as to friction being constant at different velocities was untrue.
A uniform force, therefore, was defined a force which adds equal velocities in equal times.
By observations and comparisons, it was found that what was uniform in those motions was the ratio of the velocity acquired to the time elapsed; equal velocities being added in equal times.
The bare figures convey more when they are compared with the following average annual wind-velocities quoted from a book of reference: Europe, 10.
On this occasion the wind velocities over four weeks were not so high and constant, though the snowfall was just as persistent.
These were the highest wind-velocities recorded during our two years' residence in Adelie Land and are probably the highest sustained velocities ever reported from a meteorological station.
To state the fact more accurately: such wind-velocities as prevail at sea-level in Adelie Land are known in other parts of the world only at great elevations in the atmosphere.
From the average of these figures, the velocities were: In the 16-in.
It was also desired to check by observation the relative velocities in the two pipes, as above deduced.
The relative velocities and discharges under the third test, using the nomenclature of the first and correcting the lengths of pipe on account of the removal of the 10-in.
The use of bran for determining velocities is of interest.
It follows from this axiom that two objects at rest in any two points of a time-system β are moving with equal velocities in any other time-system α along parallel lines.
Suppose that with some expositors we cut out the reference to familiar velocities such as the rate of rotation of the earth.
Its position is that if we take such time-measurements so that certain familiar velocities which seem to us to be uniform are uniform, then the laws of motion are true.
However, that relationship fails at velocities far below that of fifth-order rays.
The course had been carefully laid, with allowance for the various velocities and forces involved, to follow the easiest path to the Kondalian parade ground.
At velocities well below that of light, light-waves are shifted a minute amount, you know.
But the writer of this letter is himself inclined to deal with and use very large quantities and high accelerations and velocities in his stories.
We must not forget that force is here a sum of velocities, and accordingly cannot change direction or character unless such velocities are intrinsically changed.
But as he was unacquainted with the law of the velocities of running water as depending upon the depth of the orifice, the want of precision which appears in his results is not surprising.
Still wider differences prevail in calculating the velocities of these bodies; velocities calculated and found to correspond with the theory of evolution.
This difficulty will be of very short duration: you have only to be careful, that when you represent weights and velocities by numbers, the denominations or values of the weights and spaces, must not be changed.
And it seems still more difficult to conceive the abstractedvelocities of such nascent imperfect entities.
But the velocities of the velocities, the second, third, fourth, and fifth velocities, etc.
Within recent years spectrum research by Slipher, especially on the nebulae, has been added to the program, and the rotation and radial velocities of many nebulae have been determined.
Studies of radial velocities of the stars have hitherto been necessarily confined to the brighter stars, for the most part even to those visible to the naked eye.
Strangely the radial velocities of the clusters already observed show that most of them are traveling toward this region, and that some will enter the stellar regions within a period of the order of a hundred million years.
These great velocities appear to belong to the spiral nebulae as a class, and not to other nebulae.
Mills Observatory at Santiago, Chile, are the discoveries of stars whose velocities in space are not constant, but variable with the spectral type of the star.
On entering our upper atmosphere their temperature must be that of space, many hundred degrees below zero; and their velocities range from ten miles per second upward.
These pioneer observations of motions in the line of sight, or radial velocities as they are now called, led directly to the acceptance of the high value of spectroscopic work as an adjunct of exact astronomy in stellar research.
The Hooker telescope will enable us to determine accurate radial velocities to stars of the eleventh magnitude, which doubtless truly represent the Galaxy.
Campbell from the radial velocities of nearly 1,200 stars.
Like the earth, the other planets in the solar system are similarly oblate and by amounts dependent on the relative velocities of rotation.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "velocities" in a variety of sentences. We hope that you will now be able to make sentences using this word.
