An ice skater slides at a speed of 25 km per hr on a level ice track At this point she allows herself to coast to a complete stop How far will the person coast?
There is no way of knowing without several unstated variables. These include:air tempice tempice densityair densityrelative humidityfrictiondrag coefficient of the skater's uniformrelative angle and orientation of the skate blades
True or false a molecule with more than one kind of atom will be listed on the periodic table?
The answer to this question depends on the unstated definition of "kind of atom". All atoms of one element have the same atomic number, which equals the number of protons in nuclei of the atoms. However, atoms of the same element may have different masses because of different number of neutrons in their nuclei.

Can frequency be fractional?
I was unsure. Originally I thought...Planck's constant is supposed to be the minimal action. Multiplying by the frequency of electromagnetic radiation gives the energy of that radiation which is supposed to be quantized. So it would seem to be that only integer frequencies are allowed. Otherwise there would be continuous energy rather than quantized. If there could be 1000.5 hertz, why not pi hertz, or a millionth of a hertz, etc. But it seems very strange that frequencies can only be integers. Not only that, but given that the speed of light is now defined to be an integer, wavelengths would not be continuous either, but limited to rational fractions of a meter. Astounding! Certainly strange (if true). But upon further thought...It would be truly miraculous if any atom could emit radiation in only integer frequencies PER SECOND. The second is an arbitrary selection of time based on the cycle of our planet about our sun. To think that this is even remotely possible is truly absurd. On the other hand, the second is now measured by 'the natural resonance frequency of the cesium atom (9,192,631,770 Hz)'. Another bloody integer! But only when at rest with respect to the measurer! 'Twould seem to imply that velocities are quantized, too. Still am unsure. ============================================================================= I did not derive the formula. Einstein abstracted it from his experimental evidence. E = hf, h being the slope of his graph. The frequency doesn't change in steps of h, the energy changes in those steps. Which, again, implies the frequency is an integer, starting with one. Though I readily admit to a severely limited knowledge, I have begun to think that the author who stated that energy comes only in multiples of the Planck constant, in his attempt to describe quantization of energy, was wrong on two counts. He is not wrong about quantization, but it claiming there is an energy minimum. Frequency changes in relativity, as does energy, though it still appears to be the Planck coefficient times the frequency. Much more importantly, he referred to the Planck coefficient, as so many others do, as the Planck constant. To consider the two words equivalent leads only to unclear thinking. Coefficient is best, as it is determined by experiment, unknown to the extent of the experimental error. To call it a constant, is an act of abstraction, the act of a mathematician, a theorist, not the act of an experimental physicist whose results can be exact in only the most trivial of experiments. Constants are postulated as exact (though perhaps unknown exactly, like pi for instance); there is no error, stated or unstated, in their fundamental description (though perhaps in their limited calculation, again like pi for instance). The experimenter acknowledges that reality can never be known with infinite precision while the theorist pretends that it can. The experimenter is the ultimate arbiter.
What is an operator in quantum mechanics?
In the dirac view of quantum mechanics, operators are the center of analysis. An operator is some mathematical operation that acts on the wavefunction (psi) which returns an observable. Lets look at some examples: say psi=exp(ik(dot)r)*exp(iomega*t) (which is the case for a free particle) the momentum operator is the -ihbar gradiant applying this to our psi- we get hbar k. This is called the observable. perhaps more familiar the energy operator which would likewise return hbar omega. Now doesn't that look familiar! Interestingly enough, these two examples point out that the conservation of momentum and energy stem from the laws of physics being invariant, regardless of position and time.

What are implicit statements?
Implicit statements are ideas or messages that are not directly stated but can be inferred from context or underlying meanings. They rely on subtlety and interpretation by the listener or reader to understand the implied meaning.

What is the difference between x tends to 0 and limit of x tends to 0?
The difference can probably be stated more explicitly in mathematical terms."x tends to 0" typically implies that x is an independent variable of an unstated function. You are evaluating the function as this variable tends to zero; or, limx→0 f(x)."limit of x tends to 0" instead implies that "x" is the function, and the value of it as you approach some unstated value tends to 0; or, lima→b x(a) = 0 where "b" is the value the function is approaching, whether real or ±infinity.
