When Two Atoms Have The Same Atomic Number They Have The Same Number Of? More specifically, atoms that have the same number of protons in their nucleus belong to the same chemical element. The number of protons an atom has in its nucleus is given by the atomic number. An atom’s mass number tells you
What Is A Similarity And A Difference Between Isotopes Of An Element? Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have
Are All Atoms Of A Given Element The Same? – Atoms of a given element are identical (meaning they have the same mass and properties). – Atoms retain their identity in all chemical reactions. This is basically the Law of Conservation of matter stating that an equal amount of mass exists before and after a
Can An Object With Less Mass Have More Rotational Inertia Than An Object With More Mass? The rotational inertia of any object is less when its mass is concentrated closer to the axis of rotation. … Their different masses make no difference, just as the acceleration of free fall is not affected by different masses.
How Do Stars Differ In Mass? In more massive (main sequence) stars, there is more matter and the pressure in the core is more. … This higher rate of energy generation helps balance the greater mass and the radius of these stars is more than those of low mass stars. The story is different in
Is The Density Of A Substance Always The Same? The density of a substance is the same regardless of the size of the sample. Does the density of a substance change as the substance changes state? The density of a material does not change when we change the volume of an object. Does a density
What Does It Mean When Two Objects Have The Same Volume? Mass is a physical property of matter which pertains to the amount of matter that is contained in an object. … So if we say two objects have the same mess then can we say that they have the same volume, that they are
What Do You Mean By Equivalent One Body Problem? This center-of-mass energy is the energy involved in the interaction between the colliding bodies. … This reduction to an equivalent one-body problem greatly simplifies the solution of the motion, but it misrepresents the actual trajectories and the spatial locations of each mass in space. What is
What Is The Best Definition Of Mass? mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller
What Is The Similarities Between Mass And Weight? Both depend on the amount of matter available within the object. In fact, mass indicates the amount of matter contained in a physical body. Weight is also proportional to the amount of matter contained in a physical body. Both mass and weight are measurable and quantifiable. What
