Lesson 5 warm up problems #4

Hi, maybe I just had this misconception about work the whole time, but I don't understand why the net work is 150 J as oppose to 0J for #4. I thought the formula for work was Fdcos(theta). In the problem's case, wouldn't theta be 90 degrees since the box is being lifted straight up and remaining mot...

Physics Chapter 8 2018 edition (pg 178)

Hi, on this page, when it says refer to Figure 9 as an example of a pipe that is open on both ends, the corresponding image is of a pipe with one closed end and one open end instead. Is this an error?

Physics Chp 4 #2 and #7 practice passage

Hi, I wanted to clarify my understanding of two questions on these passages, since the explanations were a little confusing. #2: The passage claims " thermal injury risk increases when the cooling required to maintain thermal equilibrium exceeds the heat loss to the environment. What I got from the ...

:lol: Thanks, that makes more sense. The last thing I wanted to clarify is how can we assume that we can split the net dipole in half? Thanks for all the help.

#5: Doesn't the math in the picture lead to the dipole moment being 0.52? The answer is 1.5D for the question.

#7: Thanks, that makes more sense.

Re: NSTP Materials Overview

Are the old books from when I got the course in August 2019 much different from the newer versions? Can I continue to use the current books for my prep?

Chemistry and Organic chem Review book Chapter 1 Practice Passage: #5 and #7 (pg. 18)

#5: I am having a hard time understanding the book explanation for the math behind this question, especially since it was not covered in the chapter review. #7: I don't understand the explanation for why Nb is the right answer. Also is the electron config for Nb [Kr] 5s1 4d4. If so, this is another ...
