Is this a trend in evolution?
(What is the Hubble Constant?)
To figure this out, you need:
Magnitude (col 2) vs. velocity (col 7)
Distance (col 8) vs. velocity (col 7)
Find Distance from luminosity
Use absolute magnitude (col 5) and apparent (col 3) to find distance modulus
Use Figure 1 to find distance
Note: x-axis is “Apparent MINUS Absolute Magnitude”
Which graph is Hubble’s Law?
Read pages 103-104 of lab manual
Determine Hubble’s constant (also from page 103)
Use slope (Do not connect the dots, use best fit)
And percent error
can look up value online [cite source]!
Put calculations on clean sheet
Include all equations, calculations, explanations (also for finding slope)
As for error, we have been doing this all semester, here is your time to show me what you have learned!!Lab Write Up
All Power Points are on my website:http://www.physics.unc.edu/~bpohlVisit office hours or email me if you have questions! firstname.lastname@example.org
