If two groups differ only in isotopes, atomic masses are used at each step to break ties in atomic number.

If a main-sequence star is not too massive ( less than approximately 8 solar masses ), it will eventually shed enough mass to form a white dwarf having mass below the Chandrasekhar limit, which will consist of the former core of the star.

If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

If two particles have masses and, and velocities and, the total momentum is

If all masses were doubled in value you cannot tell, because all the pure numbers defined by the ratios of any pair of masses are unchanged.

If the mass of the progenitor is above 8 solar masses but below 10. 5 solar masses, the core temperature suffices to fuse carbon but not neon, in which case an oxygen-neon – magnesium white dwarf may be formed.

If the distribution of matter in each body is spherically symmetric, then the objects can be treated as point masses without approximation, as shown in the shell theorem.

If two light nuclei fuse, they will generally form a single nucleus with a slightly smaller mass than the sum of their original masses ( though this is not always the case ).

If the input nuclei are sufficiently massive, the resulting fusion product will be heavier than the sum of the reactants ' original masses, in which case the reaction requires an external source of energy.

If television was all for ratings, then what was the problem with brainwashing the masses?

If the air masses are strong enough in their respective areas during the summer there can sometimes be a massive difference in temperature between the far north / north-west of Scotland ( including the Islands ) and south-east of England-usually around 10-15 ° C ( 18-27 ° F ) but can be as much as 20 ° C ( 36 ° F ) or more.

If we assume a constant density then the masses of a shell and the sphere inside it are:

Bernays also pioneered the PR industry's use of psychology and other social sciences to design its public persuasion campaigns: If we understand the mechanism and motives of the group mind, is it not possible to control and regiment the masses according to our will without their knowing about it?

If objects within a system are in relative motion, then the invariant mass of the whole system will differ from the sum of the objects ' rest masses.

If the continental land masses were criss-crossed by a series of tunnels or canals, the sea level in these canals would also very nearly coincide with the geoid.

If masses of galaxies are derived solely from the luminosities and the mass-to-light ratios in the disk and core portions of spiral galaxies are assumed to be close to that of stars, the masses derived from the kinematics of the observed rotation and the law of gravity do not match.

If the protostar is sufficiently massive ( above 80 Jupiter masses ), hydrogen fusion follows.

If the theory has a mass gap, i. e. there are no masses between 0 and some constant greater than zero, then vacuum expectation distributions are asymptotically independent in distant regions.

If there exists a successful model, it would not only predict the masses and mixings of quarks and leptons ( and technipions ), it would explain why there are three families of each: they are the ones that fit into the ETC representations of q, and T. It should not be surprising that the construction of a successful model has proven to be very difficult.

If this difference is high, a strong westerly wind will result which in winter carries warm and humid Atlantic air masses right down to Europe.

If we think of such intervals as metal rods with uniform density, they likewise have well-defined masses.

If it were not for an old professor who made me read the classics I would have been stymied on what to do, and now I understand why they are classics ; ;

If I even hint at it do you think it will matter that you are his nephew -- and not even a blood nephew ''??

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

Defoe then commented, `` If they Could Draw that young Gentleman into Their Measures They would show themselves quickly, for they are not asham'd to Say They want only a head to Make a beginning ''.

If Jews are identified as a religious body in a controversy that comes before a national or international tribunal, it is obviously compatible with the goal of human dignity to protect freedom of worship.

If they are right, they will prevail of and by themselves.

Without preliminaries, Esther asked him, `` If you are a world citizen, will you take Garry Davis' place in his tent while he goes to the hospital ''??

If we are to believe the list of titles printed in Malraux's latest book, La Metamorphose Des Dieux, Vol. 1 ( ( 1957 ), he is still engaged in writing a large novel under his original title.

If the would-be joiner asks these questions he is not likely to be duped by extremists who are seeking to capitalize on the confusions and the patriotic apprehensions of Americans in a troubled time.

If we break the minister to our bit, we are buying back our own sins.

If the record buyer's tastes are somewhat eclectic or even the slightest bit esoteric, he will find them satisfied on educational records.

If Daddy's books are out of bounds his own picture books are not.

If it will simply delay the debates until the qualifications are closed next spring, and then carry all the candidates on a tour of debates, it can provide a service to the state.

If they are to be commended for foresight in their planning, what then is the judgment of a town council that compounds this problem during the planning stage??

If the Communists are sincere in wanting a united, neutral and disarmed Germany, it might well be advantageous for the German people in this nuclear age.

If only this could be done more often -- with such heartening results -- many of the earth's `` big problems '' would shrink to the insignificances they really are.

If any are left, presently, we may expect to see signs specifically prohibiting the feeding of them too.

If the raw population figures are crucially relevant, then it is idle to think of liberation, as idle as to suppose that Poland might liberate Russia.

If it is not enough that all of our internationalist One Worlders are advocating that we join this market, I refer you to an article in the New York Times' magazine section ( Nov. 12, 1961 ), by Mr. Eric Johnston, entitled `` We Must Join The Common Market ''.

If the UN troops are not mercenaries then the Hessians were not mercenaries either.
