(Make sure you spell it correctly for fullest credit.) Question 2: What is the name of the database we used to access this book (and others)? Question 3: Imagine one of your friends was absent during today’s discussion and wants to know what was covered because it may be on a quiz. In a paragraph or two, explain: a. How to access the database that was discussed and b. What sorts of manufacturing-related information can be found in this

Examples of measurementerrors in the news are the Hubble Telescope which had incorrect dimensions used in its lensconstruction. This was not discovered until Hubble was released into space. Later, the lens wascorrected to make Hubble useful for its intended purpose. Figure 3 shows tragic results ofcalibration error.

pre-implementation and the post-implementation surveys are aimed to gainknowledge and learn more about the students’ experiences regarding the self-directedlearning process. The initial survey mainly targeted to understand students’ socialnetwork account ownership statistics as well as to learn why they have social networkmemberships and accounts. The question regarding the membership usage is providedas: “I am a part of a social network, because: a. Everybody else is b. It is a way of representing myself c. It is my online identity d.
