The fall of the objects.
(a)
Answer to Problem 10Q
Solution:From the Astronaut’s point of view, the rock moves with a curvilinear trajectory. From the point of view of an observer outside the cylinder, a rock is observed that falls in a rectilinear trajectory (tangential to the cylinder) until it reaches the floor.
Explanation of Solution
Given info:Astronauts walking on the inside surface of the spaceship with the shape of the cylindrical shell that rotates.
Suppose that the Astronaut releases a rock inside the rotating cylinder.From the Astronaut’s point of view, the rock moves with a curvilinear trajectory as the Astronaut moves away from it. From the point of view of an observer outside the cylinder, a rock is observed that falls in a rectilinear trajectory (tangential to the cylinder) until it reaches the floor.
Conclusion:
From the Astronaut’s point of view, the rock moves with a curvilinear trajectory. From the point of view of an observer outside the cylinder, a rock is observed that falls in a rectilinear trajectory until it reaches the floor.

Answer to Problem 10Q
Solution:
Playing Basketball inside the cylinder would be totally different than on the ground.
Explanation of Solution
Given info:Astronauts walking on the inside surface of the spaceship with the shape of the cylindrical shell that rotates.
Playing Basketball inside the cylinder would be totally different than on the ground, on Earth the trajectory of a ball that is thrown into the basket is parabolic, while inside a cylinder the trajectory would be different and changes according to the location of the player and the basket inside the cylinder, either near or far from its center.
Conclusion:
The trajectory changes according to the location of the player and the basket.

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
