What is Nucleus: Definition and 420 Discussions

nuCLEus is a proposed mixed-used development complex planned for the Gateway District of downtown Cleveland, Ohio, United States. The project won unanimous approval from the Cleveland Planning Commission in November 2014, and recently received schematic design approval from the City of Cleveland in March 2019 after a thoughtful redesign to fit the city's growing population and needs in downtown Cleveland.Robert L. Stark of Cleveland-based Stark Enterprises is the lead developer on the nuCLEus.
The $300M mixed-use project will encompass approximately two million square feet in the heart of the city at the intersection between East Fourth Street, Prospect Avenue and Huron Road, connecting many of the venues in the Central Business District.
nuCLEus will serve as a mixed-use, vertically integrated space with a mix of Class A office space, retail, restaurants and residential living divided between two distinct, 24 floor towers.

    How would you find the magnetic field of a spinning nucleus?

    I'm not sure if these are very clear questions, but here goes: 1. If a fairly large nucleus is set spinning, then it should generate a small magnetic dipole, right? I'm wondering, how would you calculate it's magnetic moment, using the properties of that particular nuclide (e.g. mass, charge...

    The H (1s) electron BE=13.6eV. What about the nucleus etc?

    For a ground state Hydrogen atomic system (1 electron and 1 proton - not molecular di-hydrogen), what energies are being exerted by the proton to hold that electron? Does TE = KE + PE apply?

    What speed do subatomic particles travel around the nucleus?

    What speed do subatomic particles travel around the nucleus? Do the speeds vary with different paricles, IE Electron, Proton, Neutron? Are the speeds differnet with its idenical positron? I do know that electrons and protons travel around the nuclueus at differnt speeds, this we call "heat"...

    Why Gravity is Significant in Proton & Neutron Nuclei

    Can anyone explain to me why gravity would not be a significant force on the 'surface' of a proton or neutron? A quick calculation shows that the acceleration of a neutron toward another neutron or a proton separated by less than the radius of a neutron, is very large (compared to the radius of...

    Electrons, the nucleus and the uncertainty principle.

    I read somewhere that one of the explanations for an electron not spiraling into the nucleus is due to the uncertainty principle. If an electron falls into the nucleus both its position and velocity will be certain. How is that possible? Does the nucleus have both certainty in position and...

    Calculate the mass of unknown nucleus

    OK having a slight problem finding the mass of the unknown nucleus. Any help rearranging to find this using Newton's Gravitational law. A hydrogen nucleus and a nucleus of an ‘unknown’ atom are stationary, 5.0 x 10 ^-10 m apart. The mass of the hydrogen nucleus is mh = 1.7 x 10 - 27kg and...

    Micro-environment in cell nucleus

    Is it known what the salt conditions are like in the nucleus? For instance, in the cytoplasm [KCl]=100mM [NaCl]=10mM.. would this be very different in the nucleus? Which salts would be important in influencing protein/protein or protein/DNA interactions?

    Completely stable nucleus question

    "completely stable nucleus" question The nucleus of a helium isotope contains 2 protons. I have just worked out the magnitudes of the electrostatic force and the gravitational attraction between the 2 protons. The question now reads "the nucleus is completely stable. Considering the...

    Why do electrons orbit nucleus

    If oppositely charged particles attract, then why do electrons orbit the nucleus and not stick to it as the nucleus is positively charged and the electrons being negatively charged?

    Solving the Force & Acceleration of 8Be Nucleus

    Ok, the problem is: The nucleus of 8Be, which consists of four protons and four neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of two protons and two neutrons). (a) What is the force between the two alpha particles when they are...

    A proton colliding with a stationary carbon nucleus

    A proton of mass m undergoes a head-on elastic collision with a stationary carbon nucleus of mass 12m. The velocity of the proton is 395 m/s in the positive x direction. The velocity of the center of mass of the system is 30.38 m/s. What is the velocity of the proton after the collision?

    What is the angular velocity of an electron around the nucleus

    Can somebody tell me what is the angular velocity of an electron (more or less) around the nucleus. (it doesn't matter whether it's one in the most inner shell or the most outter, I just need an average value) thanks

    Special Relativity and radioactive nucleus

    I was wondering if I could get some guidance regarding the following question: "A radioactive nucleus, moving in a straight line, decays and emits an alpha particle. In the rest frame of the nucleus, the emitted particle moves with a velocity 6c/7, at an angle of 60 degrees to the direction...

    I beleive that light is absorbed by the nucleus of an atom

    Another way to think ... Dear reader, Now what i am writing suerly would look different from the reason give by physicists about black body absorbtion of light. Before i begin i would like to make certain things clear. 1) let's asume when more energy is given, the speed of electrons...

    Electrons in the nucleus of an atom orbit

    hello people. I am kind of stuck in this problem: electrons in the nucleus of an atom orbit around the nucleus and accelerate. They will also continously emit electromagnetic radiation and therefore they must lose energy to do so because of the conservation of energy. As a result, wouldn't...

    Quantum Physics: electron within the nucleus.

    Calculate the smallest allowed energy of an electron were trapped inside an atomic nucleus of diameter 1.4x10^-14 meters. Compare this number with the several MeV of energy binding protons and neutrons inside the nucleus. On this basis, should we expect to find electrons within the nucleus...

    Easy question: why don't electrons spin into the nucleus?

    ive read the answer so many times, i just can't think of the reason now... since the protons are positive and the electrons are negatively charged, why don't the electrons simply fall into the nucleus?
