The following question refers to the sketch of the H-R diagram.
Where in this diagram are white dwarfs? What properties do they have?
Homework Answers
In the given H-R diagram white dwarfs are in region (b) of the graph.
Properties of white dwarfs are as follows-
It is very dense and it's volume is comparable to sun.
It's luminosity is very low.
These are very hot.

2) Densities We discussed White Dwarfs and Neutron stars, very dense objects compared to stars like our sun. On the other hand, we also discussed Red Giants which are much less dense than our sun. To realize just how dense, please compute the average densities (in kg/m) for a) the sun (Rsun=7 x 10 km, Msun= 2 x 1030 kg) b) when the sun becomes a red giant (R= 1AU, M=Msun). By what factor is a Red Giant less dense...

This question refers to the circuit in the diagram. The opposition offered by the capacitor to the flow of current in this circuit: L с W R Increases steadily as the frequency of the current increases from zero Is unaffected by the frequency of the current. Decreases steadily as the frequency of the current increases from zero First decreases, then increases, as the frequency of the current increases from zero. First increases, then decreases as the frequency...
