If a laser is swept across a distant object, the spot of laser light can easily be made to move across the object at a speed greater than c. Similarly, a shadow projected onto a distant object can be made to move across the object faster than c. In neither case does the light travel from the source to the object faster than c, nor does any information travel faster than light.

If the absorption occurs in the junction's depletion region, or one diffusion length away from it, these carriers are swept from the junction by the built-in field of the depletion region.

( If a wing has a rectangular planform, rather than tapered or swept, then the chord is simply the width of the wing measured in the direction of airflow.

* Tony Palmer, in The Observer, wrote shortly after the album's release: " If there is still any doubt that Lennon and McCartney are the greatest songwriters since Schubert, then ... album The Beatles ... should surely see the last vestiges of cultural snobbery and bourgeois prejudice swept away in a deluge of joyful music making ..."

If so, it was swept away in 781, when Charlemagne had his son renamed as Pippin.

If this happens divers will not want to descend with the buoy and will prefer to release the shot line and be swept away from the shot.

If the Germans had recently swept a particular area for mines, and Bletchley Park was in need of some cribs, they might ( and apparently did on several occasions ) direct that the area be mined again.

If the target aircraft was to one side of the antenna's axis, the system would see the strength of the signal grow and fade as the beam swept across it, allowing the system to move the dish in the direction of the maximum signal and thereby track the target.

If the current cargo is not the same as the residue remaining on the barge deck, the residue should be swept up against the barge coaming and in some cases may be shoveled and placed into a container or bag.

If one rotates a line L around another line L ' skew but not perpendicular to it, the surface of revolution swept out by L is a hyperboloid of one sheet.

' If you are looking for an underrated film noir gem — that somehow got swept under the rug — this is it!

If there is much current, or the vessel is moving while dropping the anchor, it may " kite " or " skate " over the bottom due to the large fluke area acting as a sail or wing.

If Holstein-Beck's Dutch column were destroyed, the Allied army would be split in two: Eugene's wing would be isolated from Marlborough's, passing the initiative to the Franco-Bavarian forces now engaged across the whole plain.

If the right wing wants a fight, they are going to get it ... before I end up, either this Republican Party will reflect progressivism or I won't be with them anymore.

If the lift coefficient for a wing at a specified angle of attack is known ( or estimated using a method such as thin airfoil theory ), then the lift produced for specific flow conditions can be determined using the following equation:

If the air density and temperature are the same above and below a wing, a naive application of the ideal gas law requires that the pressure also be the same.

If this gene is experimentally deactivated, the haltere will develop into a fully developed wing.

If one wing is surgically removed early on, the other three will grow to a larger size.

If one animal who is lying in a battery egg farm cage could have the extra room to stretch her wing today because of something you've done, I think she would choose to have that happen.

If ... is a sharp and cynical satirisation of British politics and current affairs from a left wing perspective.

If the leading edge of the aileron is sharp or bluntly rounded, that adds significant drag to that wing and help the aircraft to yaw ( turn ) in the desired direction, but adds some unpleasant or potentially dangerous aerodynamic vibration ( flutter ).

If attached close to the wing root, it makes the stall gentle and progressive ; if attached near the wing tip, it encourages the aircraft to drop a wing when stalling.

If a forward canard is used for pitch control, rather than an aft tail, the canard is designed to meet the airflow at a slightly greater angle of attack than the wing.

If an aft tail is used, the wing is designed to stall before the tail.

If no prey ventures out in the open, Great Grey Shrikes will rummage through the undergrowth or sit near to hiding places and flash their white wing and tail markings to scare small animals into coming out.

If the critical angle is exceeded then the wing will stall and this can happen at any speed above the so-called ‘ slow stall speed .’

If this is not corrected by the pilot it causes the plane to pitch up, leading to more of the wing stalling, leading to more pitch up, and so on.

If a potential predator approaches the nest, the adult will walk away from the scrape, calling to attract the intruder and feigning a broken wing.

If startled, they can suddenly burst upwards at great speed and with a distinctive wing sound.

If the ailerons are used excessively it is probable one wing will stall ( due to the increased angle of attack ) and send the aircraft into a spin.

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 they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

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 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.
