A star’s death also depends on its mass. The most massive stars
quickly exhaust their fuel supply and explode in core-collapse
supernovae, some of the most energetic explosions in the universe. A
supernova’s radiation can easily (if only briefly) outshine the rest of
its host galaxy. The remnant stellar core will form a neutron star
or a black hole, depending on how much mass remains. If the core
contains between 1.44 and 3 solar masses, that mass will crush into a
volume just 10 to 15 miles wide before a quantum mechanical effect known
as neutron degeneracy pressure prevents total collapse. The
exact upper limit on a neutron star mass isn’t known, but around 3 solar
masses, not even neutron degeneracy pressure can combat gravity’s
inward crush, and the core collapses to form a black hole.
Recall that average velocity is given by
![v_{\rm ave}=\dfrac{\Delta x}{\Delta t}](https://tex.z-dn.net/?f=v_%7B%5Crm%20ave%7D%3D%5Cdfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t%7D)
Under constant acceleration, we also have
![v_{\rm ave}=\dfrac{v_i+v_f}2](https://tex.z-dn.net/?f=v_%7B%5Crm%20ave%7D%3D%5Cdfrac%7Bv_i%2Bv_f%7D2)
Then
![\dfrac{\Delta x}{\Delta t}=\dfrac{v_i+v_f}2](https://tex.z-dn.net/?f=%5Cdfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t%7D%3D%5Cdfrac%7Bv_i%2Bv_f%7D2)
![\implies\dfrac{110\,\mathrm m}{\Delta t}=\dfrac{22\frac{\rm m}{\rm s}+3.0\frac{\rm m}{\rm s}}2](https://tex.z-dn.net/?f=%5Cimplies%5Cdfrac%7B110%5C%2C%5Cmathrm%20m%7D%7B%5CDelta%20t%7D%3D%5Cdfrac%7B22%5Cfrac%7B%5Crm%20m%7D%7B%5Crm%20s%7D%2B3.0%5Cfrac%7B%5Crm%20m%7D%7B%5Crm%20s%7D%7D2)
![\implies\boxed{\Delta t=8.8\,\mathrm s}](https://tex.z-dn.net/?f=%5Cimplies%5Cboxed%7B%5CDelta%20t%3D8.8%5C%2C%5Cmathrm%20s%7D)
The answer is A.Yes
Explanation:
The amplitude of a wave is the height of a wave as measured from the highest point of the wave to the lowest on the wave.
We're going to remedy it with the parallelogram law.
![\alpha](https://tex.z-dn.net/?f=%20%5Calpha%20)
= one hundred eighty - 30 - 70 = eighty degrees
R = sqrt(2^2 + 3^2 - 2(2)(three) cos(80)
R = three.30 kN, we can conclude now that the value of the ensuing of R is 3.30 kN
sin
![\beta](https://tex.z-dn.net/?f=%20%5Cbeta%20)
/3 = sin(eighty)/three.304 = 63.4 stages
3.3 kN
180 + 33.4 = 213.4 degrees
63.4 - 30 = 33.4
Rutherford was the first person to make a model of an atom that was mostly accurate, the only thing is in his early model there were electrons and protons, at this time Rutherford did not know of a neutron and was not discovered until 1932.<span />
