Stellar evolution
We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.
Red Shift
It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.

Transcribed Image Text:In your lab report, do not number your analysis steps. Numerical steps are provided here for easy
reference if you have questions. Format your analysis section like previous lab reports where a template
has been provided – all tables, graphs, diagrams, and calculations need numerical, descriptive titles. All
calculations require formulas and units and final answers should be summarized or highlighted.
Calculate the average period and average frequency of rotation for each mı value. Show one sample
calculation of period and frequency and summarize the remaining results in an appropriately formatted
table.
o Don't forget to include a table title, descriptive column/row headings with units, and appropriate
formatting throughout.
Graph mı as a function of frequency of rotation by hand. This graph must be completed on the small
grid graph paper available on D2L.
o A clear picture of this graph (taken in bright light from directly overhead and cropped to show
only the graph) is to be included in the lab report after the table described in #1
Don't forget to include a descriptive graph title, axis titles including units, and a trendline (this
graph should not be linear).
Draw a free body diagram of m2 during its circular motion showing the forces acting on the mass.
Assume the mass is swinging completely horizontally. This diagram can be made digitally or by hand. It
should be labelled and included, with a figure caption, after the graph described in #2.
Using your free body diagram and the circular motion and forces equations you have learned to date,
determine and explain what m1 should be plotted against (mı is the dependent variable) to yield a
linear graph (hint: you will need to equation two formulas) that will allow you to solve for the mass of m2.
Show the two formulas separately and then equated.
o Rearrange if necessary so the formula reads m1 =
Compare this formula to y = mx+b, clearly stating what y, m, x, and b represent
Create a new data table of the data that will provide a linear graph using your answer to #4. One of the
columns will be m1.
Show a sample calculation of any data you manipulated to create this table.
Don't forget to include a table title, descriptive column/row headings with units, and appropriate
formatting throughout.
Graph m1 as a function of
graph must be completed on the small grid graph paper available on D2L. Draw a line of best fit
by hand (using the data table created in #5). This
through your data that extends to the origin.
o A clear picture of this graph (taken in bright light from directly overhead and cropped to show
only the graph) is to be included in the lab report after the above described table.
o Don't forget to include a descriptive graph title, axis titles including units, and a trendline (this
graph should be linear).
Calculate the slope of your line in the graph produced in #6. Label two coordinates on the line of best
fit. Use the slope to determine m2 (using the relationship described in #4).
The bob had an actual mass of 18.2 g. Calculate the percent error of your answer.
