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.
![Calculations and Results
1. Calculate the Average Time (s) for each Distance (m) and record these
values on your data sheet. 1s = 1000 ms
2. Calculate the Acceleration (m/s?) for each Distance by using Equation 1. Use
the average time in Equation 1. Record these values on your data sheet.
3. Calculate the Average Acceleration. Record this value on your data sheet.
4. Determine the percentage error. Assume g (accepted value) = 9.80 m/s².
Percentage error = [(Accepted Value – Experimental Value)/Accepted Value]x100](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdd39804f-6d08-4135-954a-c92ac4c2d043%2F2c786ef0-41a8-442f-95c3-71d17d3a4049%2Fz6lhr3v_processed.png&w=3840&q=75)
