This is an important step, for it affords an experimental proof that, at any rate to a first approximation, the ordinary law of force holds for electrified bodies at such exceedingly minute distances. It was also found that a resultant charge on the nucleus measured in fundamental units was about equal to the atomic number of the element. In the case of gold this number is believed from the work of Moseley to be 79. Knowing the mass of the impinging a-particle and of the atom with which...
Page 239 - ... (A) An atomic system possesses a number of states in which no emission of energy radiation takes place, even if the particles are in motion relative to each other, and such an emission is to be expected on ordinary electrodynamics. The states are denoted as "stationary" states of the system under consideration.

On the other hand, if in order to effect the conversion of velocity into pressure more rapidly, the expansion be made too violently, the fluid refuses to follow the walls, eddies result, and mechanical energy is lost by fluid friction. According to W. Froude's generally accepted view, the explanation is to be sought in the loss of velocity near the walls in consequence of fluid friction, which is such that the fluid in question is unable to penetrate...

One of these results in the emission of a radiation of a single frequency, without ionization of the gas, while the other ionizes the gas and causes it to emit a composite spectrum of radiations. The potential giving the first type of encounter may be termed a resonance potential, that giving the second type an ionization potential. The present paper is an account of an experimental...

That, because he fails to hear the sound, he is out of hearing distance. b. That, because he hears a fog signal faintly, he is at a great distance from it. c.

Page 311 - that in the case of a homogeneous incompressible fluid, whenever udx + vdy + wdz is an exact differential, not only are the ordinary equations of fluid motion satisfied, but the equations obtained when friction is taken into account are satisfied likewise. It is only the equations of condition which belong to the boundaries of the fluid that are violated.
