If the target can change its position significantly during the 30 minutes the missile is in the air on its way, the probability of the missile destroying the target is drastically reduced.

If your house is to have a forced warm air system, cooling can be a part of it.

If the brine regenerator uses high heat, they also partially sterilise the air.

If enough electric power is available, cooling can be provided by conventional air conditioning using a heat pump.

If the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter, appearing blue as a result.

If the holes are closed, the gas will only mix with ambient air at the point of combustion, that is, only after it has exited the tube at the top.

If the combustion takes place using air as the oxygen source, the nitrogen can be added to the equation, as and although it does not react, to show the composition of the flue gas:

If the air mass is colder than the ground below it, it is labeled k. If the air mass is warmer than the ground below it, it is labeled w. While air mass identification was originally used in weather forecasting during the 1950s, climatologists began to establish synoptic climatologies based on this idea in 1973.

If light pressure were the cause of the rotation, then the better the vacuum in the bulb, the less air resistance to movement, and the faster the vanes should spin.

If air is heated in a region it will expand in all directions such that the velocity field points outward from that region.

If the air cools and contracts, the divergence is negative and the region is called a sink.

If the average density ( including any air below the waterline ) of an object is less than water it will float in water and if it is more than water's it will sink in water.

If extension is executed properly the discus will be at the right angle to ride on the air current and thus be taken a farther distance.

If a larger fire is necessary, the smith increases the air flowing into the fire as well as feeding and deepening the coke heart.

If a solid surface is chilled below the dew point of the surrounding air and the surface itself is colder than freezing, frost will form on the surface.

If the indoor air is very humid, rather than moderately so, water will first condense in small droplets and then freeze into clear ice.

If the vocal folds are drawn apart, air flows between them causing no vibration, as in the production of voiceless consonants.

If too much water and not enough air surrounds the plants roots, it is possible to gradually lower the medium's water-retention capability by mixing in increasing quantities of perlite.

The valuation of the Koh-i-Noor is given in the legend that one of Nader Shah's consorts supposedly said, " If a strong man should take five stones, and throw one north, one south, one east, and one west, and the last straight up into the air, and the space between filled with gold and gems, that would equal the value of the Koh-i-noor.

If the fluid is air, the force is called an aerodynamic force.

If your pool is located on or near sloping ground, it may have natural drainage which is certainly more desirable than to be faced with the annual expense and labor of first pumping out the water and then scooping out all the debris.

`` If I could only think of something at the studio, near me, to absorb his boundless energy '', I said.

If one lives near a subway or an express parkway, the solution is to have one's wines stored with a dealer and brought home a few at a time.

If the context menu is being triggered by keyboard, such as by using Shift + F10, the context menu appears instead near the focused widget instead of the position of the pointer, to save recognition efforts.

If a forward pass is caught near a sideline or endline it is a complete pass ( or an interception ) only if a receiver catches the ball in bounds.

If the hack was particularly good, then the program might be posted on a board somewhere near one of the computers.

If the list is stored as an ordered array, then binary search is almost always more efficient than linear search as with n > 8, say, unless there is some reason to suppose that most searches will be for the small elements near the start of the sorted list.

If the solar year is defined as a tropical year, then a lunisolar calendar will give an indication of the season ; if it is taken as a sidereal year, then the calendar will predict the constellation near which the full moon may occur.

If there was not a market for natural gas near the wellhead it was virtually valueless since it had to be piped to the end user.

In after-dinner conversation at his home near Versailles, Laboulaye, an ardent supporter of the Union in the American Civil War, is supposed to have said: " If a monument should rise in the United States, as a memorial to their independence, I should think it only natural if it were built by united effort — a common work of both our nations.

If the lob is not hit deeply enough into the other court, however, an opponent near the net may then hit an overhead smash, a hard, serve-like shot, to try to end the point.

If we imagine looking at the Earth from space, we see that the whole Earth was pulled, but the near oceans more and the far oceans less ; the far oceans stayed behind since they are pulled less ( since they are farther away ).

If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular and the pH shifts less with small additions of titrant near the equivalence point.

If the first officer had stopped making these inputs at any time before the vertical stabilizer separation, the natural stability of the airplane would have returned the sideslip angle to near 0 °, and the accident would have been avoided.

If plasmon losses have energies near that of an Auger peak, the less intense Auger process may become dwarfed by the plasmon peak.

If there is enough low level wind shear, the column of hot, rising air can develop a small cyclonic motion that can be seen near the ground.

If it is the case that Cnut was part of this, his birthdate may be near 990, or even 980.

If the baseline value is large or if it is not subtracted out of the image, then the computed D4σ value will be larger than the actual value because the baseline value near the edges of the sensor are weighted in the D4σ integral by x < sup > 2 </ sup >.

If a battery has been completely discharged ( e. g. the car lights were left on overnight ) and next is given a fast charge for only a few minutes, then during the short charging time it develops only a charge near the interface.

If one considers the flux of the electric field vector, E, for a tube near a point charge in the field the charge but not containing it with sides formed by lines tangent to the field, the flux for the sides is zero and there is an equal and opposite flux at both ends of the tube.

If the micrometer is in good condition, then they are all so near to zero that the instrument seems to read essentially " dead-on " all along its range ; no noticeable error is seen at any locale.

If Israel's very existence is threatened, some speculate that she would use a " Samson Option ," a " last resort " deterrence strategy of massive retaliation with nuclear weapons, may be initiated should the state of Israel be substantially damaged and / or near destruction.

If too much ground water is pumped near the coast, salt-water may intrude into freshwater aquifers causing contamination of potable freshwater supplies.

If air near the surface becomes extremely warm and unstable, its upward motion can become quite explosive resulting in towering clouds that can break through the tropopause or cause severe weather.

If the stone is positioned near a bone ( usually a rib in the case of kidney stones ), this treatment may be more uncomfortable because the shock waves can cause a mild resonance in the bone which can be felt by the patient.
