If, for some reason such as economy, we are not going to develop aircraft nuclear propulsion with a sense of national urgency, then we should turn our effort to developing jet engines with a thrust-to-weight ratio of 12 or 15 to one.

If a person ‘ synthesizes ’ a ‘ jet plane landing ’ sound, this is achieved mostly by altering the shape of the mouth to filter the white noise into pink noise by removing the higher frequencies.

If a jet aircraft is at full throttle but is tied to a very strong tree with a very strong chain, then the jet engine produces no propulsive power.

If the erupted jet is unable to heat the surrounding air sufficiently, convection currents will not be strong enough to carry the plume upwards and it falls, flowing down the flanks of the volcano.

If the jet emits a burst of energy every minute in its own rest frame this may be observed on Earth as being a much faster release, perhaps one burst every ten seconds.

If a jet engine were to run in " reverse " in this context, it would take in ambient heat and exhaust fumes to generate kerosene and oxygen.

If ( i. e. when velocity of jet is close to the velocity of light ) then despite the fact that < math >

He reported a narrow escape when, at the foot of the mountain, a jet of steam came out of the ground over which he and his party had just passed: " If it had struck any one of us we would have been scalded to death ".

If the nozzle pressure ratio is above the critical value ( about 1. 8: 1 ) a convergent nozzle will choke, resulting in some of the expansion to atmospheric pressure taking place downstream of the throat ( i. e. smallest flow area ), in the jet wake.

If an incoming HEAT jet penetrates the outer shell and forms a bridge between the shells, the electrical energy discharges through the jet, disrupting it.

If the associated jet stream is stronger than normal and there is colder than normal air in place in central Canada to provide a greater than normal temperature contrast with Gulf of Mexico moisture drawn northward by the developing panhandle low, surface cyclogenesis can be particularly energetic and cause a great swath of heavy snow to develop and blanket a large portion of the American Great Plains and upper-midwestern states in conjunction with very strong winds, the combination of which exceeds blizzard criteria.

If the molecular cohesion of the liquid is sufficiently high, stream breakup does not occur ( if it does, droplets are electrosprayed ) and a charged liquid jet is formed.

If the jet is oriented along the line of sight to Earth, relativistic beaming will change its apparent brightness.

If M and N are two smooth manifolds, how do we define the jet of a function?

If the mouth is open the jet may project several feet.

If the jet wave is survived, there is a short respite, then the next round of helicopters begins with an extra row of helicopters on the first run.

If the jet had an opening angle of only a few degrees, the burst energy could have been thousands of times lower.

If a stream or jet of air is directed through a flame, fuel air mixing is enhanced and the jet exiting the flame is intensely hot.

If the glass is cooled quickly in the absence of a strong light source by putting ice on the glass or placing it in the freezer with the door almost closed, it turns backwards ( i. e. the silver sides trail ).

If we insert vertices in random order, it turns out ( by a somewhat intricate proof ) that each insertion will flip, on average, only O ( 1 ) triangles – although sometimes it will flip many more.

If a search request turns up a result, the node that has the result contacts the searcher.

If, supposing it turns out that the original Ship of Theseus, S1, was actually stolen property, and the rightful owner demands its return, should the police give him S2 or S3?

Critic Rex Reed wrote, " If you want to see what turns a B movie into a classic [...] don't miss Night of the Living Dead.

If the turns of the coil are oriented perpendicularly to the magnetic field lines, the flux is the product of the magnetic flux density B and the area A through which it cuts.

If the flux in the core is purely sinusoidal, the relationship for either winding between its rms voltage E < sub > rms </ sub > of the winding, and the supply frequency f, number of turns N, core cross-sectional area a and peak magnetic flux density B is given by the universal EMF equation:

If neither player had won by the tenth turn, subsequent turns consisted of moving one of one's own tokens to the remaining empty hole, with the constraint that this move could only be from an adjacent hole.

If the wheel is leaned away from the vertical so that the top of the wheel moves to the left, the forward rim of the wheel also turns to the left.

If either player turns up such a card, his opponent has to pay a penalty: four cards for an ace, three for a King, two for a Queen, or one for a Jack.

De Camp's most highly regarded works in the genre are his time travel and alternate history stories, including Lest Darkness Fall ( 1939 ), " The Wheels of If " ( 1940 ), " A Gun for Dinosaur " ( 1956 ), " Aristotle and the Gun " ( 1958 ), and The Glory That Was ( 1960 ) – in the last of which the " time travel " actually turns out to be a tour de force of historical recreation.

* If the inferior power is in an aggressive position, however, and / or turns to tactics prohibited by the laws of war ( jus in bello ), its success depends on the superior power's refraining from like tactics.

* If a person exposes their forearm and closes their eyes or turns their head in the opposite direction while a second person slowly traces a finger from the wrist upward to the crook of the elbow, many people are unable to say when the crease of their elbow is being touched.

* If a person turns their tongue upside down, and runs their finger along the front, it will feel like the finger is moving in the opposite direction.

If the legend were true, and if the priests were able to move disks at a rate of one per second, using the smallest number of moves, it would take them 2 < sup > 64 </ sup >− 1 seconds or roughly 585 billion years or 18, 446, 744, 073, 709, 551, 615 turns to finish, much longer than the predicted lifespan of the sun.

If the load resistance is smaller than the source resistance, then most of the power ends up being dissipated in the source, and although the total power dissipated is higher, due to a lower total resistance, it turns out that the amount dissipated in the load is reduced.

If one of the batsman turns to complete runs after the first without grounding his person or equipment behind the popping crease, then a short run is signalled by the umpire tapping his near shoulder with his fingers and the short runs are not scored.

If a virus is detected, the window turns red and the scan is stopped, and the alert is shown once you exit the screensaver ) or a distributed computing application ( such as the SETI @ home project ).

If the area available for the windings is filled up, more turns require going to a smaller diameter of wire, which has higher resistance, which cancels the advantage of using more turns.

If the player steps forward and turns left, Klaymen will face the castle and if the player clicks on the castle, Klogg can be heard laughing.

If blood can get in, but cannot get out because one of the veins has been blocked, that part of the body turns purple.

If the player is able to get rid of her face-up card in one of these ways, she turns up her next card and attempts to discard it using the same methods.

If we take the modules to be over a field, then the dimension of the n-th homology of X turns out to be the number of " holes " in X at dimension n.

If the curved track turns the cars 60 degrees, and three rail lines meet as three equally spaced spokes, 120 degrees apart, then the curved track sitting on a turn table can be rotated to connect any two of the three rail lines at this junction, creating a triangle junction.
