The jeans equations: (a) consider the dark matter density profile p(r) (5) 4πgr2 which gives rise to constant rotation curves mal" and isotropic suppose that the dark matter is "isother- so that the 1d velocity dispersion o2 = a^0,d the jeans equation analog for "hydrostatic equilibrium" in spherical coordinates and =const. wvrite down v2/2 for this system show o2 galaxy at large radius r 3.5, but they contribute mass to the system. again using the jeans equations (but using gravity set (b) next consider their distribution is approximately spherical with p. c population of stars which orbit the same a negligible by the dark matter of equation 5), solve for o2

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

overcharge is the right answer system

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
