What is nominal scale? And is it different from nominal dimensions?

Does anyone have the period-luminosity relationship for type II cepheids? I can only find type I.

I have been asked several times, including on my Regional test, how many pixels are in this image. I don't have examples of this because it was on a Regional test, but can someone explain how you are supposed to be able to tell? (All the answer choices were low numbers, but I thought there were a lo...

A pulsar has a mass of 2.5E30 kg and a radius of 3E4 m. a) What is its rotational inertia? b) If it's initial period is 1.6 s, what is it's rotational kinematic energy? c) Given that it has a spin down rate of .0006 s/y, find the rate of kinematic loss of the pulsar. Answer|a) [math]I = \frac{2}{5}...

A pulsar has a mass of 2.5E30 kg and a radius of 3E4 m.
a) What is its rotational inertia?
b) If it's initial period is 1.6 s, what is it's rotational kinematic energy?
c) Given that it has a spin down rate of .0006 s/y, find the rate of kinematic loss of the pulsar.

I'm actually clueless as to which DSO this is... Image 1. What DSO was this data gathered from? 2. Is this image a spectrum, light curve, or radial velocity graph? (meta question to anyone who can answer - what would be a good way to phrase this without listing options?) 3. What orbital phenomenon ...

Image 1. What DSO was this data gathered from? 2. Is this image a spectrum, light curve, or radial velocity graph? (meta question to anyone who can answer - what would be a good way to phrase this without listing options?) 3. What orbital phenomenon does this image show? 4. How many times brighter ...

A star has three times the mass of the sun, what would its schwarzschild radius be? (Also how do you hide your answer behind an answer box and how do you upload math equations to show work?)
