Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
Fusions of atoms heavier than hydrogen like helium takes place in the core of the star, at the core the temperature and density of gases is the greatest .
A record player has a velocity of 33.33 RPM. How fast is the record spinning in m/s at a distance of 0.085 m from the center? [0.297 m/s] 6. A merry-go-round a.k.a “the spinny thing” is rotating at 15 RPM, and has a radius of 1.75 m A.
<span>vf^2 = vi^2 + 2*a*d --- vf = velocity final vi = velocity initial a = acceleration d = distance --- since the airplane is decelerating to zero, vf = 0 --- 0 = 55*55 + 2*(-2.5)*d d = (-55*55)/(2*(-2.5)) d = 605 meters
