Considering your answer to the above question, how does this timescale for the Sun's evaporation by the solar wind compare to the age of the Universe? O The solar wind evaporation time is much longer than the age of the Universe O The solar wind evaporation time is much shorter than the age of the Universe O The solar wind evaporation time is close to the age of the Universe (ie, within a few billion years
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.

![Assume that the solar wind causes the Sun to lose mass at a rate of 1.4 x 10° kg/s. If you assume the wind is emitted a constant rate, estimate
the time (in units of Gyr -Gigayears 10 years) that it will take the entire Sun to evaporate via its solar wind emission.
(Of course, the rate won't be constant throughout the lifetime of the Sun---this is just a rough estimate to understand the timescale associated
with this process.)
[Hint: you need to look up a number and do several unit conversions. This is a "rate" problem. Enter your answer as an integer or decimal, NOT in scientific
notation. I'm asking for the answer in Gyr, which is why--if you compute everything correctly-you will get a number that is manageable without the
need to use scientific notation.]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff2d5267d-4124-4e4c-8429-645249326cab%2F191318b0-53d3-449b-8a22-78e481e90522%2Fdpvhnl_processed.jpeg&w=3840&q=75)
