Contrast the internal structures and properties of neutron stars with white dwarf and main sequence stars.
 
  Specifically, what processes in each balance the inward pull of gravity; what are their energy sources; and what are their sizes, densities, and temperatures?

Question 2

What does angular resolution measure?
 
  A) the angular size of the smallest features that the telescope can see
  B) the brightness of an image
  C) the size of an image
  D) the number of electromagnetic waves captured by an image

Answer to Question 1

Main sequence: Internal structure is hydrogen fusing to helium, which provides energy. Outward heat pressure balances gravity. Size: around 106 km. Density: 103 kg/m3. Temperature: 107 K in core, 6000 K at surface.
White dwarf: Internal structure is ultra-compressed carbon; energy from residual heat; gravity balanced by electron degeneracy; Size: 104 km; Density: 109 kg/m3; Temperature: 5  104 K at surface.
Neutron star: Internal structure is tight-packed neutrons; gravity balanced by neutron degeneracy; energy from rotational kinetic energy and residual heat; Size: 10 km; Density: 1018 kg/m3; Temperature: unknown.

Answer to Question 2

A

Immunoglobulin injections may give short-term protection against, or reduce severity of certain diseases. They help people who have an inherited problem making their own antibodies, or those who are having certain types of cancer treatments.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
