The Sun’s motion if the light coming from a point on its left edge has a slightly higher

Explanation of Solution
Introduction:
The frequency of wave varies when the source and observer move towards or away from each other. This effect on frequency is known as Doppler effect.
The Doppler effect occurs for both mechanical and
The frequency perceived by a detector is morethan that of the source when the source moves towards the detector, whereas, frequency perceived by a detector is less than that of the source if the source moves away from the detector. This implies that the left side of the Sun is towards the Earth and the right side is away from it. Thus, it can be assumed the Sun must be rotating in the same manner as the Earth.
Conclusion:
Thus, the left side of the Sun is towards the Earth and the right side is away from it. The Sun must be rotating in the same manner as Earth.

Also, how would you be able to tell for the other vowels?arrow_forwardYou want to fabricate a soft microfluidic chip like the one below. How would you go about fabricating this chip knowing that you are targeting a channel with a square cross-sectional profile of 200 μm by 200 μm. What materials and steps would you use and why? Disregard the process to form the inlet and outlet. Square Cross Sectionarrow_forward1. What are the key steps involved in the fabrication of a semiconductor device. 2. You are hired by a chip manufacturing company, and you are asked to prepare a silicon wafer with the pattern below. Describe the process you would use. High Aspect Ratio Trenches Undoped Si Wafer P-doped Si 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…arrow_forward
