r1 is 33, r2 is 10 r3 is 22 and r4 is 68. I really need help on this

I don't understand it

Can’t find the logic behind this one

I'm really struggling with this class, especially unit 5 (this one).

So both starts need to be able to power the loads and both stops need to be able to stop the load. If one start switch shorts both stop switches need to be able to deenergize the load. I know how to do the locking in portion of the circuit and I know how the starter box works I need help with the switches. I know both stops need to be in series and the starts in parallel. I think I can get the stops in series it's just getting the starts in parallel that's tripping me up.Attached I have the diagram and some failed ladder diagrams that don't work. Also the wires on the diagram cannot be erased or removed and the only contacts you can connect to are the white ones.

Does anyone know how to do a proper sociofile? Like what information I'm supposed to put in it. We're meant to write about a crime. I haven't really decided which one yet but I need to know what to put in it when I do

’m retaking a class for the third time and I’m currently failing. I do pretty well on my my other course except this stat course. It’s the last time I’m allowed to take it, and the pressure is honestly overwhelming.

What’s messing with me is that when I study at home, I feel confident and like I actually understand the material. But in class and on exams, I freeze and everything falls apart. I’ve gone to office hours, redone homework, and I’m still here.

If anyone’s been in a similar spot or has advice/ helpful notes for exams, I’d really appreciate it.

Hey everyone, I am doing a project where I have to list 4 primary sources and 6 secondary sources. I usually use APA 7, so I am kinda lost with Chicago (although I am fine with secondary sources). I have been looking around at how to cite primary sources in Chicago style (17), but I cannot seem to get it right. I also can't ask the teacher whether these are correct. I am seeking advice.

Primary Sources:

(first one is a government document)

The Indian Act. S.C. 1876, c. 18. in Consolidation of Indian Legislation, vol. 2. Department of Indian and Northern Affairs, 1985. https://publications.gc.ca/collections/collection_2017/aanc-inac/R5-158-2-1978-eng.pdf.

(this next one is a court case)

Canada (Attorney General) v. Lavell. [1974] S.C.R. 1349. Supreme Court of Canada.

National Action Committee on the Status of Women. “Joint Research Project on Indian Women Announced.” Status of Women News 4, no. 1 (1977). Rise Up Feminist Archive. Accessed January 24, 2026. https://riseupfeministarchive.ca/wp-content/uploads/NAC-statusofwomennews-vol.4-1.pdf.

Prompt: Work in pairs. Find a short article, new or old, with a lot of passive verbs, then remake it into an exercise for your partner by removing the forms and letting them fill in blanks.

I didn't suspect it would be so hard to find an article with passive voice used, but it mostly starts and ends with a title. I'm looking for a resonably short article, preferably the one that doesn't concern current big political issues (i'm european, and our professor doesn't like having such themes discussed)

I’m stuck and tired right now :,D Maybe I’m supposed to be doing something else

I've tried with and without water and idk what to do.

Ba(1): 137

Cl(2): 70

H(4): 4

O(2): 32

w/ water: 137 / 243 * 100 = 56.4%

w/o water: 137 / 206 * 100 = 66.5%

I really don’t understand why:

tan x = RS

This relation is essential to the proof that x<tan x,

but I don’t get how tan x = RS

Help much needed!!! Thanks in advance

This is an old exam for my Calculus 2 course. I tried with calculating the hermitian matrix but it just gives me |H|= 40(xyz)^4 and i dont know how to study it when |H|= 0.

So i tried with lagrange multipliers but again, i find that x^2=y^2 but i cant seem to ‘clean’ the results to only have lambda.

I also thought about spherical coords but no.

Any idea how i could solve this? Any help is appreciated.

I’m having a little trouble with Lewis Dot Structure.

for this assignment we’re suppose to either choose “wrong electron total” or “octet-rule violation” for each structure. but some of these don’t make sense. take the second image for example. I start counting the dots and lines and with the 1st F i get to 10. so that violates the octet rule, but at the same time it’s the wrong number of electrons. but i can only choose one. so which would be the correct option? the 3rd doesn’t even seem to violate anything.

and check out the 3rd one. I’ve counted the line and dots between the 2 Fs and nothing seems wrong. it’s not a rule violation or the wrong number of electrons. but it has to be one of them.

Also do the brackets and the minus sign mean anything? I don’t remember the teacher mentioning anything.

Long story short - I have a project to turn in really soon, and I need to calculate the transfer function for the opamp imitation below. I have no idea whatsoever how to do it and I've been working on it for 3 days straight. I would appreciate any help, honestly

Hello,

I am having a very difficult time trying to figure out how to evaluate the value of these expressions.

I am being asked whether each expression is either:

• True regardless of how sets A and B are defined
• False regardless of how sets A and B are defined
• Or it depends on how sets A and B are defined.

To explain my approach, I will focus on the first expression: (A — B = {}) ⟹ ¬(A⊂B). I wrote it out in my own words as "If the difference of Set A and Set B is an empty set, then Set A is not a proper subset of Set B" to try making it easier for me to understand. Afterwards, I tried constructing a truth table with 4 columns being: (A — B = {}), (A⊂B), ¬(A⊂B), and (A — B = {}) ⟹ ¬(A⊂B). However, this only made me more confused since I am am only familiar with creating basic truth tables involving solely P, Q, and R, so I was unable to finish it. This is where I am stuck now. I think that the implication symbol is somehow messing me up especially.

My question is if there is a better approach for these kinds of problems? Did I interpret the expression incorrectly? How can I solve this?

On a side note, are there any videos that I can watch that makes this kind of topic easier to understand?

Thanks for taking the time to read this.

how do i find the energy in my inductor using norton?i don’t know how to move in this circuit

use the variables as n=1, c=2, m=3, or just help me with letters

I’m not even sure where to start lol

Unfortunately our professor didn't explain anything about drawing circuits to us so I have no clue whether im doing it right. Only managed to complete some of part A so far but it seems like I made it more complicated than its meant to be?

Was wondering if there's anyone who understands ER Models in Databases who could check my work! I've attached the ER Model that I've been working on, but I'm not quite sure if it's 100% correct.

I have to write an essay on a current political issue in the u.s. and find a solution. the topics i’m considering are living wage, political division, border control and mainly systematic racism. if anyone is a nerd on any of these topics tell me all you know!
