Hi!
For this fluid statics problem,
One of the answers is:
However, why did they assume the pressure at the top was zero? I thought the pressure at the top would be 1 atm?
So tried to take atmospheric pressure into account putting 1 atm at the top,
Do you please know how to get P_0A/2 so...
i need to make up 22,000 per year

I think its simple interest but am having a hard time remembering all.
Hi,
I'm watching a video about Hartley oscillator and I'm in trouble with a simple assumption: as stated at minute 5:50 if the two coils ##L_1## and ##L_2## are wound on the same core then taking into account the mutual inductance M he gets:
##L^ {'} _1 = L_1 + M##
##L^ {'} _2 = L_2 + M##...
I'm going to graduate in May 2020 with an Accounting / Finance degree. Without trying to sound prideful, I am an extremely bright student and have a 3.80 GPA with very very minimal effort. However, after doing a few internships, I'm realizing more and more than I definitely do not want to be in...
Suppose light travels during a time interval of t2 - t1, where the scale factors at t1 and t2 are a(t1) and a(t2) respectively.
If we consider an infinitesimally small interval of time dt during this interval, without accounting for expansion we would expect light to travel a distance cdt. How...
I keep hearing that the relative speed of light remains constant because time and lengths change with speed, what I believe is called the Lorentz factor. At slow speeds the Lorentz factor is extremely small, so what do people believe accounts for the rest of the change?
If I travel...
is it PHP-MySQL?
In websites accounts of users tend to be stored in servers, and on these servers they store the data in some syntax and use PHP, RUBY or something else to add/change the information.
Is it the same in bank accounts? In what format is banking information stored?
Hello,
I was told that I could post questions related to Financial Accounting Fundamentals on the Pre-calculas Math section of Physics Forum. But everytime I post questions related to this topic, I don't get any replies or help. Am I posting in the wrong category??

I am currently on the path to receive my AA in General Studies by the Spring of 2016. From there, I will transfer to University and intend to acquire a BS in Information Technology. I previously wanted to major in Psychology but realize I do not want to enroll in another 6 years to complete...
Greetings - We speak of astronomical objects as being x number of light years away, which is also a statement about the age of the data. So our knowledge of M83, for example, is about 15 million years old, etc, etc. I'm just wondering why there never seems to be any attempt to move this...
Hello everyone!
I am trying to write an app that needs to be able to tell if a vehicle is accelerating or breaking. In this sense I used the accelerometer in the phone. At the moment I managed to isolate and subtract the gravitational pull of the Earth from my readings and I am using a noise...
Dear everyone,
I am an international student. I graduated with BS in International Business 2 years ago. After going to work, I realized I am interested in mathematics rather than competing another. I want to be an accountant in the future. But I believe it takes professional degree, to be a...

Consider a bar of length L, mass M, and uniform density floating in free space (ie: neglect gravity and assume that it is not contacting anything). The bar is initially stationary. Imagine a bullet of mass m traveling at a speed v hits the bar at one end. What is the...
I used to like physics, until I did a bachelors in it.
In my final year now (at a Top 20 university in the world) and even though I am currently passing with a reasonably good grade, I still don't know what I am doing.
I still sit clueless in lectures, even after 3 whole years. I never...
So I've gotten close to the correct answer for this problem, but I think I'm accounting for the DI water incorrectly:
In titrating a blank, 0.11 mL of sodium hydroxide solution was required to titrate 50.00 mL of DI water. It required 17.56 mL of the same sodium hydroxide solution to titrate...
This is a conservation of momentum/energy lab. We have an air track with motion sensors at both ends. Bumpers are staged to give elastic collisions. There are two gliders on the track. For this part the second glider remains stationary near the center of the track. The first glider is sent to...
i am helping my girl with her accounting II homework. i just jumped in and the math seems easy enough. her textbook seems kind of vague, was just wondering if i could bounce a few questions off someone. may be get a few formulas i missed in accounting I.
Not sure if this is better suited to the careers forum but anyhow. I sort of know the difference between those 4 fields but I was just wondering if anyone could explain the differences in more detail, I've got another 3 days work experience that I haven't got anything for so I was thinking on...

Hello,
I would like to know how to calculate the velocity of an object in a circular path, accounting for friction. I know that in a frictionless environment, the equation for the velocity is v2=F*R/M.
