You stand on a merry-go-round which is spinning at f = 0:25 revolutions per second. You are R = 200 cm from the center. (a) Find
the angular speed ! At which it is spinning. (b) Find the centripetal acceleration, ac with which it is spinning. (c) What is the minimum coefficient of static friction is between your shoes and the floor that will keep you from slipping off?
A prominence is a loop of cool incandescent gas that extends above the photosphere. A solar flare is an explosive release of energy that comes from the sun and causes magnetic ditrubances.
In accordance to Quantum Mechanical model of an atom:
The Principle Quantum number (n) gives the description of the shell of an electron and the energy level of an electron in an atom.
The angular momentum also referred to as Azimuthal Quantum number (l) gives the description of the shape of the orbitals and helps in determination of angular momentum magnitude.
The magnetic quantum number () describes the energy levels or the number of orbitals contained in a subshell and the way these are oriented within.
The spin quantum no. () determines the elelctron spin's direction which may be () or ().
