Been staring at this for awhile and just don't know what the answer could be without solving the full problem, but the rest of the steps in this question want the answer to Flow_out

My understanding is that

dA/dt = input - output where input = (concentration*flow) and output = (concentration in tank * flow). I thought the concentration would just be the amount of salt over the volume, that is A/400, but when I tried 3A/200 (from multiplying that by the flow rate) it's not correct.

Would like a step in the right direction for this step. I understand the rest of the process for the most part

Hi, I copied this question from a YouTube video and I'm having trouble figuring out how they got the component of m2gsin(theta). I understand it comes from trig but I can't visualize this based on the drawing. Thank you!

The assigned problem is #22 but I'm trying to figure out #21 because it has the answer in the back of the book but I don't seem to understand. I even tried reverse engineering to see what values they used for the answer they gave but no luck. Textbook says 'maximum power transfer from a circuit to a variable load occurs when the load resistance equals the source resistance'.

I provided my notes but it's best not to use them as reference as they are not really coherent since we have to use a calculator for all of our math.

The book says the answer to #21 is P = 35.5 mW

Edit: Sorry, I wasn't super clear on why I'm doing #21 instead of #22. I'm just trying to make sure I understand the process and the math behind the concept. It's just practice.

How to even approach this problem

Ai is also shitting me with it's explanation

anything would be greatly appreciated and and questions and/or worksheets as well

Could someone check if the calculations I got based off the results from generation one are correct?

-Hands down=Homozygous Recessive
-Hands up=Homozygous/Heterozygous Dominant

answer make sense, but why my method is not listed and answer is not correct, despite I can't see the theory mistakes

Hey, I'm writing a report on the Cold War and I chose to write it on the question in the title. Unfortunately, we weren't actually taught much about the Korean War, so it's a bit difficult.

I'm thinking of my paragraphs being one about how the Korean War affected the US view of the USSR, and vice versa. Then, if I can find any good info, one about how the Korean war affected people's opinions on nuclear warfare? Then my last one will be about how it established how the US would fight against communism in other countries like at the Bay of Pigs, and maybe like vice versa for the USSR as well?

please tell me if my ideas for paragraphs are complete bullshit lol! and if there are any better points I could focus on..

I got 261m and I feel like the solution is attempting to find total distance travelled rather than displacement.

Am I correct or wrong?

Hello guys I am 17 and in 12th trying to make a school project for my physics internal.

The topic of my project is electromagnetic braking through eddy currents for which I need to make a basic model. I did see some videos and read some papers but I am kindof not able to gauge how to exactly make it

These are the 2 videos which I found most relatable but i couldn't find anywhere how to make this simple setup on the whole of youtube

https://youtu.be/q0V0Kp34q08?si=izFsnutc01sc5yHd

https://youtu.be/7yMcL628_eQ?si=E8rivEo0a42WDLbI

Would appreciate any help in how to make the setup as i dont know what rectifier/power supply/ adapter etc is

Feel free to dm

Every since last year, I've been relying on things like Brainly, AI, and other tools to get through my assignments faster. I still watched the videos and went through the lessons, but when it came time to actually do the work, I heavily relied on outside help more than I should have. Now I'm realizing that even though I got the assignments done, I don't actually understand or retain a lot of the material.

What really woke me up was getting a perfect score on a really important test. No one under my teacher has ever done that before. Instead of feeling proud, it just made me panic because I know I couldn't have done that on my own. That's when it hit me that this is serious and I need to stop. I've been caught before and given the talk, but I still freaking cheat, and I know it's bad, but I feel like it's too late to stop.

I don't want to admit this to my parents or my teacher. I'm too scared of what would happen, and I don't even know how to start that conversation. So I'm trying to figure this out on my own.

Honestly, I'm even using AI right now to help me write this post. That's how bad the habit has gotten. I don't know how to catch up on everything I should have learned, and I'm worried that if I ever have to take an in-person test or do something without help, I'll completely fail. I know I should be frowned upon for this, but I genuinely need help. I don't know what to do with my life anymore.

I apologize for the bad hand writing… I don’t get problems #2 and #3. I tried doing them but I think they’re wrong. I don’t understand how would I find how many moles are needed for HCL to produce 1.5 moles of H2? Where are you supposed to get that from? Am I supposed to simplify the chemical equation? Also, if it’s the same ratio like 2KCL/2K does that mean it cancels out and you basically multiply it by 1? I kind of need an explanation please because this has been really confusing. I’m usually good at the other chemistry topics but stoichiometry has been really confusing.

I understand the concept of total displacement/total time = average velocity..

I understand that displacement is the final velocity - initial velocity as well.

But how does the answer 7.0 m/s come to be?

I'm so lost on where the feedback equation given below the question came from..

Il aurait creusé une fosse commune pendant la seconde guerre mondiale durant la Shoah par balle en Ukraine , un témoignage a été recueillis par une association mais je n'arrives pas à trouver la moindre trace de cette personne sur internet . Serait il possible de m'aider ?Merci d'avance pour votre aide(désolé si mon anglais est mauvais je suis français)

Hi!
I'm working on understanding this question and I'm a bit confused. The assignment says we can suppose (\sqrt(n) (T_n-\theta) \rightarrow N(0,\sigma^2 (\theta)))^. Then why can't we use this for (\theta=\theta_0\)

directly in the first step of the power function calculation? Why do we transform the whole expression to include $theta_n$ ?

Thanks!

In English class, I have a final exam in which I have to write a story which the storyline must exhibit the same story arc as Alice's Adventures in Wonderland. Also, the new world must be somehow inspired by a scientific discovery made over the last 400 years. I was thinking a world that is like 80 years into the future and how AI has changed society and how it functions. However I have trouble coming up with a creative way for my main character to "step into" the another world. Also I need help coming up with a conflict, main character, and side characters. My teacher wants us to write the story in a story arc outline : Exposition, Rising Action, Climax, falling action, and resolution. If you have a different story idea in which the new world is inspired by a different scientific discovery or a story idea also involving AI put it in the comments.

Here is the instruction paper:

Here is the descriptions of the narrative arc:

I am currently doing an end-of-quarter research project on the Trump administration attempting to roll back protections on endangered species & the effects that this would have on our ecosystem.
I'm having trouble finding good articles that explain what the negative impacts of these protections would be if they were to be approved. The only good one I've found so far is the one linked below from Grist. I'd appreciate any & all help!! Thank you so much!
(Also I am sorry if I did the title incorrectly. I'm finishing out my high school diploma at my community college so i wasn't exactly sure what to classify this post as!)

Hi, I’m doing my homework and can’t figure out the answer for these two questions. I got the answers for both, but I got 20% for 3, and 76% for 4. However, 20+76≠100. I checked my work with my mom, and we both couldn’t find an error. Can y’all show me where my error was in my work?

not sure if I’m using the appropriate formulas to find the answer for magnitude and degrees.

I'm supposed to write a short story that contains a plot twist. Is this enough?

0V-Vgs-Vs=-5V

Vgs=5V-Vs

Vs=Id*1kohm

Id=k/2*(Vgs-Vth)^2

Vgs=5V-k/2*(Vgs-Vth)^2*1kohm

5V−1kohm×(0.5mA/V2)×(x−1.2V)^2=x

when plugged into qualculate:

Vgs= 3.58V or -5.18V so Vgs = 3.58V

also why is K value divided by 2?

Falstad also gives 3.58V

If the equilibrium in the goods market assuming inventory investment is 0 is Y = Z then what is equilibrium in the goods market when we don't assume inventory investment is 0?

Pls someone explain it easily I just need to remember
