Homework Help: Cumulative problem

  1. Jan 28, 2008 #1
    Neutron stars are believed to be composed of solid nuclear matter, primarily neutrons.

    A. Assume the radius of a neutron to be approximately 1.0*10^-13cm , and calculate the density of a neutron. [Hint: For a sphere V=(4/3)(pie symbol)r^3.]


    B. Assuming that a neutron star has the same density as a neutron, calculate the mass (in kg) of a small piece of a neutron star the size of a spherical pebble with a radius of 0.18 mm.
