Question
Chapter 1, Problem 1RQ
To determine
The description of Milky Way when observed with the naked eye.
Expert Solution & Answer
Answer to Problem 1RQ
Option (e)
Explanation of Solution
Galaxy is defined as the group of stars, star cluster gas and dust and every galaxy is located far away from one another.
Collection of all the things called as universe; it contains stars, planets, galaxies, dust, gas, dark matter and all other things that are known. Milky Way Galaxy is the part of the universe and is one of the millions of galaxies that exist in the universe.
Solar System is the part of Milky Way Galaxy; it contains eight planets, dwarf planets, asteroid and other astronomical object with Sun as only Star; all the objects orbit around the Sun directly and indirectly.
Conclusion:
Milky Way is the collection of stars of which Sun is also the part ad stars and Sun both are visible with the naked eye. Thus, option (e) is correct.
The path taken by planet across the sky is imaginary so it cannot be observed. Thus, option (a) is incorrect.
Debris left by the motion of planets is found nearby stars, it is the part of Milky Way which is not visible by naked eye. Thus, option (b) is incorrect.
When comets collide they result in debris but that happens in space so it is not visible by naked eye. Thus, option (c) is incorrect.
The asteroid belt exists between terrestrial planets and giant planets and it is visible using telescope. Thus, option (d) is incorrect.
Due to scattering on sun light from water vapour in the atmosphere, rainbow is obtained and it is not part of Milky way, it is a natural phenomenon. Thus, option (f) is incorrect.

3. You would like to deposit material within a high aspect ratio trench. What approach would you
use and why?
4. A person is setting up a small clean room space to carry out an outreach activity to educate high
school students about patterning using photolithography. They obtained a positive photoresist, a
used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask
with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full
resist gets developed, and they are unable to transfer the pattern onto the resist. Help them
troubleshoot and find out why pattern of transfer has not been successful.
5. You are given a composite…
