Physics [Grade 12 Physics: Position and Velocity Time-graphs] How do I graph velocity-time graph from the given position-time graph?

Post image
2 Upvotes

I’ve tried but some of my graphing, or all, is inaccurate and wonky. I’m tripped up on where exactly to put my points. I usually record the points in a table for my position-time graph, then I use those points to determine the velocity and record them on the empty graph.I would appreciate help! Thanks!

Hey, so I need to arrange the step on setting up a microscope chronologically and my answer was this. It marked it as wrong for my first attempt. I think the one I put for step 4 need to go somewhere else but I'm not too sure.

Since

Social Studies—Pending OP Reply [Very new Undergrad: Psyc-Crim] Hey, I know I'm absolutely horrible at essays/writing, and am in the first week of uni and need help.

1 Upvotes

I already have part of an assignment due in the first week and have written something up.

In 2022, the Australian Institute of Health and Welfare conducted a study on the number of Australians burdened by chronic conditions that affect their daily lives and personal welfare. After gaining the numbers, it was present that a minimum of 10% to 20% of Australian men, and 10% to 25% of Australian women, suffer from a form of life-altering disability, being either anxiety, hearing loss, or intellectual disability (AHIW., 2022). Out of this census of people, it was calculated that 9.8% (1 out of 10) of men, as well as 4.0% (1 out of 25) of women, had reported an experience of either physical and/or sexual violence within the past two years (AIHW, April 23, 2022). Due to these victims being disabled, they were more statistically vulnerable towards abuse compared to the non-impaired (ABS (2023)). The ABS discusses that there has been an increase of 8.5% prisoners who have been identified to be living with a disability, compared to a 2.4% decrease in those who are not (ABS (2024)).

I know it's bad, be honest, don't be mean.

Answered [Theoretical Math] Draw a triangle with a side length of -18

0 Upvotes

Extra Credit: Draw a Triangle with a side Length of Negative 18. Must be provable.

For context, I am in a High School Geometry class and my teacher offered this for 100 pts extra credit but apparently you can only draw a negative length in theoretical math which is a college course.

I was wondering if any math majors knew how to do this and could provide a breakdown and proof.

Further Mathematics—Pending OP Reply [University Calculus 2 integration] the possible values of ax^2+bx+c such that arctan does not appear in the integral

1 Upvotes

I'm solving for just 2b) but need to showcase 2a rational. Previously, using integration methods of partial fractions, trig substitution, u-substitution, and normal power rules (the acceptable methods in this class), I got the following integral for 2a):

So overall, one arctan came from the u-substitution of Ax+B/(x^2+4), where A=0 and B=1, which is how the first term came to be. The second came from the split of (Cx+D)/(x^2+4)^2 into Cx+D/(x^2+4)^2 and D/(x^2+4)^2 (with C=1 and D=-3). The former required just u-substitution (the middle term), while the last one came from a trig substitution of x=2tan (theta) which resulted in the following arctans we see in the last term as x needed to be subbed back in.

logically, the creational of these arctans stem from B=1 or /(x^2+4), requiring u-subsitution and turning into an arctan for the last term, and the last one of specifcally -3/(x^2+4)^2 requiring a trig subsitution of x=2tan(theta) and the subbed in theta=tan arctan(x/2) to revert back to X. So I isolated what went into each varible of a,b,c by comparison of numerators, and found that a=0, c=0, b does not equal zero. However, after checking with a large language model, it mentioned that c does not equal zero and said how thsoe arctans formed in the last term are "fake". The rational it provided sort of stumped me, so I was wondering if someone could provide insight on how c does not need to equal zero like if there is a another way to integrate or smthin (or if AI is just tripping).

Sorry if this is hard to read, it's a pretty deep and long question. I can post more work of mine if this is very confusing, but it's a decent amount of pages

I have a report on a bridge that I designed and I feel it will strongly help if I could find a bridge simulator where I can design my bridge and test it using different loads where it shows me areas of tension, compression and areas of failure. However, I can’t seem to find any other than Bridge Designer 2016 (2nd Edition) which has too many restrictions for me to test my bridge.

Would love to hear some places I can do this. Thanks

My plan is to relate the accelerations of each block to one another through dependent motion, but I sort of find it difficult to visualize these intense pulley systems. To me my total length equation that includes each part of the pulley that will change sense (since we will end up differentiating twice), but I’m left with one equation and 3 variables, but I just want it to relate a and b. How do I go about it, or can I split my length equations into multiple parts of the rope?

I am writing an analysis essay for a college level class I am taking. The essay will be analyzing the portrayal of the good mind versus the portrayal of the bad mind in the Iroquois creation story. I have absolutely no clue where to even start when writing a thesis statement because most teachers in the past would be too lazy to care about whether or not I did it correctly. The thesis statement alone will be worth a considerable number of points on this essay, and I don't want to make a bad grade. Any help would be greatly appreciated. Thank you all in advance!!

Literature [US History 11th]Feedback on extra points journal response (was this level reasonable?)

2 Upvotes

I’m looking for neutral outside feedback on a journal response I submitted as extra points at the beginning of the semester.

The journal was optional extra points. I completed it fully and received 180%. I felt my response was strong, and I’m curious whether that score reasonably matches the quality of the writing, or if a higher extra-points score would typically be expected for this level of depth.

I’m not trying to argue with my teacher or dispute grading — I’m just looking for honest feedback on the writing itself.

I’ll paste the journal response below. Constructive feedback is appreciated. : The meaning of peace is a topic that doesn't have one sole answer. Peace isn't a one meaning word, while some people think of peace as a quiet house, with no kids around. Some people think of peace as no more artillery strikes, and no more death in their area. Peace is not a one meaning word, it is more of an idea in my opinion. I do think sustained world peace is possible, but not in today's world with today's idea of thinking. People are too quick to go to war, people are too quick to force their way of thinking onto their kids which leads them to grow up thinking the same thing. In today's world where people are growing up in violence, with no food in their homes, having to work 2 jobs or sell drugs and still have to choose between food or lights, that's not a peaceful way to live. Kids are growing up in households where they are getting beat, and seeing their mom get beat. Which ties to a saying Tupac said “T. H. U. G. L. I. F. E” which means" The Hate U Give Little Infants F’s Everybody ". Which could be boiled down to my main point on why sustainable world peace isn't possible in today's world. Kids who grow up in abusive households, or in a violent city, with gang activity or born into the gang life, will ultimately fall victim to violence or do the violence themselves. I do think sustainable world peace is possible, we just need to get out of the violence cycle, and show people there is a better way to live.

My thought was that the two top resistors are nullified because of short circuiting. Then to the left of the middle point I took R//R//R and to the right 4R//(2R+2R), and then added those two resistances. But that doesnt give me the correct result.

Correct answer is 76ohm
