Energy and mass equivalence

For all nuclear reactions the conservation laws (number of nucleons, charge, sum of mass and energy equivalent of mass, momentum, angular momentum, parity) are valid. The main differences between chemical reactions and nuclear reactions are the following ... 

Answer Mass is converted into energy through the fission process. Therefore, the total mass of particles after fission is less than the mass of the interacting particles before fission. The difference in mass is converted into energy of the fission process. See Table 2 of Chapter 1 for mass and energy equivalents. 

The evidence on which this theory of stellar evolution is based comes not only from known nuclear reactions and the relativistic equivalence of mass and energy, but also from the spectroscopic analysis of the light reaching us from the stars. This leads to the spectral classification of stars, which is the cornerstone of modem experimental astrophysics. The spectroscopic analysis of starlight reveals much information about the... 

A similar finite-differenced equivalent for the energy balance equation (including axial dispersion effects) may be derived. The simulation example DISRET involves the axial dispersion of both mass and energy and is based on the work of Ramirez (1976). A related model without reaction is used in the simulation example FILTWASH. 

Einstein showed that mass and energy are equivalent. Energy can be converted into mass, and mass into energy. They are related by Einstein s equation ... 

This famous equation expresses the relationship between mass and energy, and its validity has been amply demonstrated. This equation does not indicate that a photon has a mass. It does signify that because a photon has energy, its energy is equivalent to some mass. However, for a given photon there is only one energy, so... 

Obviously the motions of encounter and of mean free path do not necessarily have any meaning here nor are they needed. On the other hand, the relaxation time x is easy lo define, e.g., as the time taken by sound to travel unit distance, as computed in the equivalent body in equilibrium (equivalent, in having the same total mass and energy in "V"). 

This example illustrates another result of the theory of relativity, namely, the equivalence of mass and energy. Rewriting the Iasi equation. 

Principle 3. There is equivalency between particles masses and energies. 

This recognition that energy and mass are equivalent is the most important conclusion of special relativity. Classically there are separate conservation laws for mass and energy, which is now replaced by a conservation law for total mass-energy. Any closed system that suffers a change in mass shows an increase in kinetic energy which may be written... 

In this book the value of A is given in energy units rather than units of mass, which is possible because of the equivalence of mass and energy expressed in Einstein s... 

Einstein published a mathematical equation to express the equivalency of mass and energy. The equation is... 

Now Tm going to tell you about a strange concept that s necessary for understanding radioactivity and other nuclear reactions. That concept is the equivalence of mass and energy. Mass can transform into energy, and vice versa. This is part of Einstein s theory of special relativity and is the source of that famous equation E = m. Let s apply the theory to the activities you did in the previous section. When the two magnets are apart, we say that they have potential energy due to... 

There is an equivalence between mass and energy. Whenever a system transfers energy elsewhere, that system loses mass. Energy gains result in an increase in mass.
