thanks Thank you, I'll be sure to check this out!

thanks Thank you for the reply and putting me on the right track.

How can an astronomer recognize a double star from the characteristic frequencies of the light that reaches him from its member stars? I have looked and looked in my textbook but I cannot come up with the answer to this one. Thank you! mmfoley

Thank you Thank you for the quick response and help! mmfoley

thank you thank you both!

Hello, How do the mass and weight of an object at the Earth's center compare with their values at the Earth's surface? My textbook is pretty terrible for the non-physics major. I think they answer this question in eqations rather than plain English, so I'm having a hard time with this...

Thank you - one more question Thank you for the help. Here is another question: How do the mass and weight of an object at the Earth's center compare with their values at the Earth's surface? I believe that as you move closer to the Earth's center you get the gravitational attraction...

Thank you Thank you! I was at least on the right track, I just got it backwards.

Hello, I am taking a Natural and Physical Sciences course. As math and sciences aren't my strongest subjects, I am really struggling, reading things over and over again, and they are just not sinking in. For example, I understand the acceleration of gravity - g. I think that something can...
