A village is a clustered human settlement or community, larger than a hamlet but smaller than a town (although the word is often used to describe both hamlets and smaller towns), with a population typically ranging from a few hundred to a few thousand. Though villages are often located in rural areas, the term urban village is also applied to certain urban neighborhoods. Villages are normally permanent, with fixed dwellings; however, transient villages can occur. Further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement. In the past, villages were a usual form of community for societies that practice subsistence agriculture, and also for some non-agricultural societies. In Great Britain, a hamlet earned the right to be called a village when it built a church. In many cultures, towns and cities were few, with only a small proportion of the population living in them. The Industrial Revolution attracted people in larger numbers to work in mills and factories; the concentration of people caused many villages to grow into towns and cities. This also enabled specialization of labor and crafts, and development of many trades. The trend of urbanization continues, though not always in connection with industrialization. Historically homes were situated together for sociability and defence, and land surrounding the living quarters was farmed. Traditional fishing villages were based on artisan fishing and located adjacent to fishing grounds.
In toponomastic terminology, names of individual villages are called comonyms (from Ancient Greek κώμη / village and ὄνομα / name).
Hello. I am joining this forum in hopes of expanding my physics knowledge and improving my accuracy in my current AP Physics Class. This class has been awful. I am normally top of my class, including AP Calculus BC, so I have a firm grasp of studying and mathematics. I am hoping to be a...
I'm guessing this question can be solved using the law of conservation of momentum
Vi = 5 m/s
(5 m/s) M = (4.33 m/s) cos30 M + V sinθ M
I don't know what to do after this... I'm also not sure if I use the sin and cos correctly.

Greetings to all.
I'm looking for the best textbook for introductory physics that has clear explanations and is problem-oriented. I'd also appreciate any recommendations for textbooks for the AP Physics 1 exam.
My HS senior son is taking AP Calc this year and struggled with the first quiz, which was a review of some more difficult algebra - factoring higher degree polynomials, simplifying complicated fractions etc. Ordered him Schaum’s Int algebra for practice problems, but curious about any advice...
What are some of the hardest concepts to learn in AP E&M? I am going to prepare for the exam with my previous physics teacher. I am currently a senior enrolled in AP Calc BC, and I already took AP Mechanics.
Hi! Feel free to yell at me if this is the wrong forum; I'm a little new at this.
I'm self-studying AP Physics 1 and 2 this year, and so far it's going quite well! My only fear is that, because I don't have a specific AP Physics teacher, there may be something really important about the...
Hellooooooo I am a rising 11th grader that is participating in my school's AP Seminar program. As an aspiring astrophysicist, I wanted to do a research project on some sort of topic in this area. Any ideas? Just to give a background of my knowledge/ the level I am at, I am going into AP calculus...
If you have a collection of questions (possibly with your answers) that students have asked during AP Physics or PHY 101 (so high school or college level physics) I would love to hear from you. As "experts", it is very difficult for us to imagine the questions that novices (first time learners...

screen shot to avoid typos
OK the key said it was D
I surfed for about half hour trying to find a solution to this but $f'(0)$ doesn't equal any of these numbers
$e^0=\pm 1$ from the $e^{(x^2-1)^2}$
kinda ?
$\tiny{4.2.5}$
$\displaystyle\int^1_0{xe^x\ dx}$
is equal to
$A.\ \ {1}\quad B. \ \ {-1}\quad C. \ \ {2-e}\quad D.\ \ {\dfrac{e^2}{2}}\quad E.\ \ {e-1}$
ok I think this is ok possible typos
but curious if this could be solve not using IBP since the only variable is x
Evaluate $\displaystyle\int\dfrac{e^{2x}}{1+e^x} \, dx=$
$a.\quad \tan^{-1}e^x+C$
$b.\quad 1+e^x-\ln(1+e^1)+C$
$c.\quad x-x+\ln |1+e^x|+C$
$d.\quad e^x+\frac{1}{(e^x+1)^2}+C$
$e.\quad {none}$
ok I was going to use $u=1+e^x\quad du=e^x dx$ but maybe not best
btw I tried to use...
$\displaystyle\lim_{x \to 0}\dfrac{1-\cos^2(2x)}{(2x)^2}=$
by quick observation it is seen that this will go to $\dfrac{0}{0)}$
so L'H rule becomes the tool to use
but first steps were illusive
the calculator returned 1 for the Limit
1. $f(x)=(2x+1)^3$ and let g be the inverse function of f. Given that$f(0)=1$ what is the value of $g'(1)$?

Ok I thot I posted this before but after a major hunt no find

Mahalo ahead
If $f^{-1}(x)$ is the inverse of $f(x)=e^{2x}$, then $f^{-1}(x)=$$a. \ln\dfrac{2}{x}$

ok well it isn't just adding the areas of 2 functions but is $xf(x)$ as an integrand
Yahoo had an answer to this but its never in Latex so I couldn't understand how they got $\dfrac{7}{2}$
$\displaystyle g'=2xe^{kx}+e^{kx}kx^2$
we are given $ x=\dfrac{2}{3}$ then
$\displaystyle g'=\dfrac{4}{3}e^\left(\dfrac{2k}{3}\right)+e^\left({\dfrac{2k}{3}}\right)\dfrac{4k}{9}$

ok from online computer I got this
$\displaystyle\int_0^x e^{-t^2}=\frac{\sqrt{\pi }}{2}\text{erf}\left(t\right)+C$
not sure what erf(t) means
OK, this can only be done by observation so since we have v(t) I chose e
but the eq should have a minus sign.

image due to graph, I tried to duplicate this sin wave on desmos but was not able to.
so with sin and cos it just switches to back and forth for the derivatives so thot a this could be done just by observation but doesn't the graph move by the transformations
well anyway?
A particle moves along the x-axis. The velocity of the particle at time t is $6t - t^2$.
What is the total distance traveled by the particle from time $t = 0$ to $t = 3$
ok we are given $v(t)$ so we do not have to derive it from a(t) since the initial $t=0$ we just plug in the $t=3$ into $v(t)$...
ok these always baffle me because f(t) is not known. however if $f'(t)>0$ then that means the slope is aways positive which could be just a line. but could not picture this to work in the tables.
Im sure the answer can be found quickly online but I don't learn by copy and paste. d was...
I think I have solved the first three, and only really need help on question four.
For number one, I used Fc = (Mv^2)/R and just rearranged it for velocity so I ended up with v = sqrt(ac * R)

For number 3 I used w = Ff*d and got w = -Mg*mu*l...

ok I think (a) could just be done by observation by just adding up obvious areas
but (b) and (c) are a litte ?
sorry had to post this before the lab closes

well apparently all we can do is solve this by observation
which would be the slope as x moves in the positive direction
e appears to be the only interval where the slope is always increasing
