There are four main categories of galaxies:
(i) Spiral Galaxy
(ii) Barred Spiral Galaxy
(iii) Elliptical Galaxy
(iv) Irregular Galaxy

When using the high power in a microscope, is the objective lens located close or far away from the microscope slide?
Question 7 1 pts Now assume that all of these galaxies are the same actual size (say, approximately 95,000 light years in diameter). Which galaxy is the farthest away? O NGC 2903 O NGC 3471 O NGC 6217 - NGC 3368 O NGC 5248
The boiling points of valeraldehyde and crotonaldehyde are too close to make a clear identification. How can the two aldehydes be identified?
Imagine you are nearsighted (can only see close objects clearly and far objects are blurry). At your last eye doctor
Bringing a charge qq from very far away to a positon close to another fixed charge changes the potential energy of the two charges by ΔU=−2.0nJΔU=−2.0nJ If the potential difference for the first charge is ΔV=−2.0VΔV=−2.0V, what is its charge?
