Answer:
The assumptions we make when we infer the mass of a galaxy cluster from observations of the spectra of its constituent galaxies is thermal hydrostatic equilibrium
Explanation:
In galaxy cluster observation, thermal X-ray emission from the hot intracluster gas measures directly the gas density and temperature distributions within the cluster. This hot gas is confined by and expected to trace the underlying three-dimensional gravitational potential. Under the assumption of thermal hydrostatic equilibrium, these gas properties may be used to infer the cluster total mass distribution.
Hence, the assumptions we make when we infer the mass of a galaxy cluster from observations of the spectra of its constituent galaxies is thermal hydrostatic.
Hi, I would believe so, because rain is a physical property
<span>Copper sulfate, CuSO4 ===> (Cu^2+) (SO4^2-). </span>
<span>That means copper ions have a positive charge in the solution of this compound and are therefore attracted to the negative electrode, cathode. Just wanted to clear that out because "it accepts electrons there" is an invalid and ambiguous answer. </span>
<span>Good luck.</span>
