" If a magnetic sail orients at an angle relative to the solar wind, charged particles are deflected preferentially to one side and the magnetic sail is pushed laterally.

If the wind speed is high, then the flux through the net is large.

If the net is made bigger, then the flux would be larger even though the wind speed is the same.

If the net opening is parallel to the wind, then no wind will be moving through the net.

If a star grows outside of its Roche lobe too fast for all abundant matter to be transferred to the other component, it is also possible that matter will leave the system through other Lagrange points or as stellar wind, thus being effectively lost to both components.

If the wet soil beneath is the major source of vapour, however ( this type of dew formation is called distillation ), wind always seems to be adverse.

If a planet's magnetic field is strong enough, its interaction with the solar wind forms a magnetosphere.

If the wind is blowing from the jumpers front to their rear, only minor corrections need be made to remain facing into the wind.

If the wind is blowing from left to right, the jumper reaches up high on the left risers and pulls them down into their chest, holding them until landing.

If the wind is blowing from their rear to their front, they will reach up high on their rear risers and pull them down into their chest and hold them until they land.

If the wind is blowing from the jumpers front to their rear, the front risers are pulled down into the chest and held until landing.

If one is left-handed and wears the watch on the right wrist, one has to remove the watch from the wrist to reset the time or to wind the watch.

If one wanted to predict exactly how high a thrown ball would rise or exactly where and when it would hit the ground, it would be necessary to make a detailed calculation based on precise information about the ball, the altitude, the wind, and the force of the initial throw.

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

For looping the Golden Gate Bridge, for flying at low level down Market Street in San Francisco and for blowing the clothes off of an Oakland woman's clothesline, Bong was reprimanded by General George C. Kenney, commanding officer of the Fourth Air Force, who told him, " If you didn't want to fly down Market Street, I wouldn't have you in my Air Force, but you are not to do it any more and I mean what I say.

If such plutonium were used in a " gun assembly ," the chain reaction would start in the split seconds before the critical mass was assembled, blowing the weapon apart before it would have any great effect ( this is known as a fizzle ).

If a strong wind is blowing from the west it will be against the tide in places along the course, causing the water to become very rough.

* If there is blowing sand the filter may protect the lens from abrasion from sand

If so, the wind must have been blowing from the southwest — otherwise there was no gain in this manoeuvre — but this makes it difficult to explain how the English fleet, sailing to the south, could be swifter than the Dutch.

If the speed of sound in the steam supplied to a whistle were 15936 inches per second, a pipe with a 15-inch effective length blowing its natural frequency would sound near Middle C: 15936 /( 4 x 15 ) = 266 Hz.

* Steam aperture width – If gas flow is restricted by the area of the steam aperture, widening the aperture will increase the sound level for a fixed blowing pressure.

If so, the actin filaments that form at the front might stabilize the added membrane so that a structured extension, or lamella, is formed rather than the cell's blowing bubbles ( or " blebs ") at its front.
