Alright that makes sense, but won't there still be "intermediate" lines, where the particles are moving outwards on a vector that isn't directly in our line of sight. Then, we will only be able to account for only the component of their velocity that IS in our line of sight, making it appear to...
I'm doing a project on the Crab Nebula for my first-year astronomy class and I am finding the spectroscopy a bit puzzling. What I have read is that the normal emission line for a particular gas is split into two, one red shifted and one blue shifted. This of course is accounted for by the Dopler...
A question from my asronomy class...
Given that we are able to measure positions, velocities and timescales of objects in our universe, what sort of physical properties can we determine for objects that orbit each other in the universe?
I have tried reading through my textbook for ideas...
Girls (well me at least) like to know that they have someone that they can talk to. Yes, we do have girlfriends for that, but sometimes you just can't talk to girls. Sometimes it is just easier to talk to guys. Guys are definitely easier to live with sometimes.
Yeah i admit that I am an...
The pH was measured using Universal Indicator Solution (30 drops in each flask). The cultures were growing for approximately a week and they were all shaken on a semi-daily basis. the oxygen in the anaerobic ones was not sucked out at the begginning, but were corked with very little air in the...
I need help writing a discussion for the biology lab report that I'm doing. If anyone could help in explaining the results it would be much appriciated. Here's the experiment...
We had 6 flasks each containing yeast, sugar and water. 2 of the six we added 5ml of 1.0 M HCl and into two others...
