Rate of rotation (angular momentum) As of now, we can only measure the mass of the black hole reliably by the movement of other objects around it. If a black hole has a companion (nearby stars or disks of material), it is possible to measure the radius of rotation or speed of...
From an environmental and diplomatic standpoint, however, the use of the B61-11 raises a number of issues. There is no way for any known penetrating bomb to bury itself deeply enough to contain a nuclear blast. This means that the B61-11 would leave an immense crater and eject a huge ...
In plasma, theelectrons separate from the nucleus. Once the energy of heat releases the electrons from the atom, the electrons begin to move around quickly. The electrons are negatively charged, and they leave behind their positively charged nuclei. These positively charged nuclei are known as ion...
Find the radius of a hydrogen atom in the n = 2 state according to Bohr's theory. Why is Rutherford's model called the nuclear atom? Why did Rutherford change Thomson's model of the atom? What are the limitations of Rutherford's model of the atom?
Numbers like that can make your eyes cross just trying to keep track of the zeroes! Here's another one. The latest guess for the radius of a proton (the small, positive particle in the nucleus of an atom) is 841 quintillionth meters, or 0.841 femtometers. That's less than a ...
Considering spherical symmetry, the luminosity is obtained as LWD = 4π RWD Qtot r2dr , 0 (3.8) where RWD is the radius of the WD. For our computations, we have chosen a representative value of MWD = 1 M⊙ for the mass of the WD. However, the results are not altered by picking ...
Using the trends in ionic radius, the elements can be ranked by size as follows: He < O < P < Be < Li Step 3:Apply coulomb's law to rank the given elements by ionization energy. Although helium only has an effective nuclear charge of 2, it is much smaller than ...
How did Ernest Rutherford discover the nucleus of the atom? What happens to the atomic number in positron decay? How to calculate Bohr radius What is the process of neutron irradiation in isotope production? Why were the subatomic particles discovered in this order: electron, proton, neutr...
you perpetually fall around the planet rather than down to the surface. Similarly, electrons orbit around the nucleus. Even if they fall toward it, they are moving too fast to 'stick'. Sometimes electrons get enough energy to break free or the nucleus attracts additional electrons. These behavi...
