It was supposed to combine the light of two distinct bodies, one, of a gaseous nature, moving rapidly away from the earth, the other, giving a more sunlike spectrum, approaching it with even higher speed. The relative velocity determined at Potsdam for these oppositely flying masses amounted to 550 miles a second. And this prodigious rate of separation was fully maintained during six weeks!
Up to the limit of their capacity, six-inch pipes properly laid are greatly to be preferred, as insuring a deeper stream which will more generally attain the velocity of three feet per second, needed to move the heavier constituents of the sewage. The difference in cost between six-inch and eight-inch pipes will be sufficient to cover any extra cost of the most careful workmanship.
From the perpendicular pitch to these islands, a distance of more than one hundred yards, the water glides down a sloping rock with a velocity almost equal to that of its fall; above this fall the river bends suddenly to the northward.
From the Court the news soon reached the town. Events have a weight, and the mathematical rule of velocity, increasing in proportion to the squares of the distance, applies to them. They fall upon the public, and work themselves through it with the most astounding rapidity. At seven o'clock no one in London had caught wind of the story; by eight Gwynplaine was the talk of the town.
Events are now moving in silent speed, almost with velocity, indeed; and I sometimes feel oppressed by the strange and preternatural ease which seems to accompany their flow. Charles is staying at the neighbouring town; he is only waiting for the marriage licence; when obtained he is to come here, be quietly married to her, and carry her off.
With this description of engine more speed than power is obtained, and hence it is used for passenger trains, where a high velocity is required, and where there is usually little weight, comparatively speaking, to draw. The others have only four wheels, not so large as the two just described, but all driven by the machinery.
You can see that they are not prepared. They will not attempt to attack us until they have made their landing." The Martians Land. And Mr. Edison was right. With gradually accelerated velocity, and yet very, very slowly in comparison with the speed they would have exhibited in falling upon such a planet as the earth, the Martians and their car came down to the ground.
And all these motions are performed with strength and velocity in proportion to the energy of the sensation that excites them, and the quantity of sensorial power. Many of the motions of our organs of sense, or ideas, that were originally excited into action by irritation, become in like manner more frequently causable by our sensations of pleasure or pain.
The power and range needed by a given detector depends on the relative velocity the greater that velocity, the more power, the greater range needed. At one mile per second, a ship needs a range of only thirty miles to spot an obstacle thirty seconds away; at ten miles per second, it needs a range of three hundred miles.
The screen was apparently in itself a coign of vantage, flying through space with the velocity of light, and the watchers gasped involuntarily and drew themselves together, as with that unthinkable speed they flashed down toward the surface of Callisto.
