Historically, the introduction of technology has caused profound changes in the labor market and, temporarily at least, displace
vekshin1

Technological advancement and the need for humanity to obtain faster and more efficient processes in all social sectors has caused a strong automation of several jobs that were previously done manually, by workers. The automation of these services, allows a faster, but efficient, more standardized and more economical production. This has hindered the entry of workers into the productive sector, causing major layoffs, competitions and wage cuts. Agricultural countries, such as Brazil, for example, even replace about 300 workers, with only one harvester machine, controlled by software and only one driver. This scenario is worrying for workers, but this only tends to grow and become more and more common in our society.

However, this substitution of human labor for automation is a reality for manual and manual labor, which is not the case for software engineering. Software engineering works with the creation, monitoring, specification and development of software (which are used in automation, including). These processes need to be carried out by human hands, which shows that automation will not negatively affect software engineers, at least at the moment we live in today.

Assume that light of wavelength 6000A is coming from a star. What is the limit of resolution of a telescope whose objective has
Paul [167]

Answer:

θ=0.0288 radian

Explanation:

resolution limit is the minimum angular separation of  two sources that can be viewed  distinctly    by telescope

\theta =\frac{1.22\times \lambda}{D}

\lambda=6000\times 10^{-8} cm=6 \times 10^{-5} cm

d=100 inch=100\times 2.54=254cm

\theta = \frac{1.22 \times 6 \times 10^{-5}}{254}

θ=0.0288 radian
