the age of the material
One thing that is not a factor in determining critical mass is the type of chemical reaction taking place. Critical mass is primarily determined by the concentration and type of fissile material, geometry of the material, and surrounding materials affecting neutron moderation.
Studying mass media law and ethics is important for a student of mass communication because it provides the necessary understanding of legal regulations and ethical guidelines that govern the media industry. This knowledge helps students navigate complex media landscapes, adhere to professional standards, and avoid legal issues that could impact their work and credibility in the field. Understanding these principles also enhances critical thinking skills and promotes responsible reporting.
A hypothesis is a proposed explanation for a phenomenon that can be tested through research, while a theory is a well-established explanation that has been repeatedly tested and supported by evidence. A law is a statement that describes a natural phenomenon but does not attempt to explain why it occurs. Laws are typically based on empirical observations and are more straightforward than theories.
The four fundamental laws of stellar structure are: 1) Hydrostatic equilibrium - balance between pressure and gravity within the star, 2) Energy transport - mechanism by which energy is transported from the core to the surface, 3) Energy generation - fusion reactions that produce energy within the core of the star, and 4) Mass continuity - conservation of mass within the star.
The Homestead Act, the mass killing of buffalo, and the completion of the Transcontinental Railroad are most closely associated with the westward expansion of the United States during the 19th century. These events played significant roles in the settlement and economic development of the American West.
Graham's law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. In other words, lighter gases effuse or diffuse at a faster rate than heavier gases under the same conditions.
The age of the material.
Mass is a major factor.

The most important factor is the stars mass.
The main factor is its mass.
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
critical mass
mass and speedKE = 1/2mv2, where m is mass in kg, and vis velocity in m/s.
At less than critical mass, there are fewer "targets" for neutrons to strike, fission, and release more neutrons. As a result, the reaction dies out.
A mass balance.
Critical Mass - Catholic rock - was created in 1996.
The effect of gravity is measured.
