Hi, so someone probably has already asked this, but does temperature increase or decrease with depth in a fluid? I thought it would decrease since it has more pressure but it is probably wrong, or doesn't make sense. I was confused because the ocean gets colder the deeper you go, but then does...
(I Live in Michigan - no power at home since yesterday, and likely not until Sunday - 4 days, because of high winds.)
My software genius boss (really, he's very smart,) is trying to tell me that the reason that the power companies do not bury power lines, is because it costs money to push it...
Dear friends.
I am a cardiovascular health researcher writing on behalf of my research team based in Copenhagen, Denmark. We plan to conduct a high-altitude field study on cardiopulmonary function assesed by ultrasound on Aconcagua summit in near 7000 meters altitude. Reports say it will be...
Hello everyone,
I am predicting the altitude of a model rocket based on some testing I did where I found the impulse of a little single stage model rocket motor. I am wondering how to incorporate drag into my calculations to make it more accurate. I know D=Cd*rho*v^2*A and I can definitely find...
Is there any equation in order to know how high my rocket will go, before launching it? I suppose that if there is any, it will not take into account air drag and others, and there is no need for that. I just one to know an approximate, I am making a summer project with some friends and we had...
1. Homework Statement
Hi!
I need to find the opening angle of the loss cone at a given altitude, when the magnetic latitude is 65 deg.
2. Homework Equations
See below
3. The Attempt at a Solution
First, I used the following equation to calculate the magnetic field at a given altitude...
1. Homework Statement
I need an equation for a physics project, and I'm not sure which to use. I am given the distance and time variables, however I don't have the angle or altitude they are looking for. Which equation do I need to use?
2. Homework Equations
Velocity related equations? fab...
1. Homework Statement
I have the time and distance measurements. We shot it straight up, how can I find the altitude and angles? Times: (6.58 sec, 23 m), (6.90 sec, .6 m) (6.20 sec, 10 m). The time represents how long it takes for the rocket to shoot up and fall, the distance is the measurement...
I read an article a day or so ago titled Hydrostatic Lapse, which makes the case for a phenomenon that I thought was well and truly confirmed; that gravity is responsible for the cooling of air with altitude. However I discover in the sequel article The Gemini Cycle that this phenomenon is...
1. Homework Statement
A) Suppose you are on Earth's equator and observe a satellite passing directly overhead and moving from west to east in the sky. Exactly 12.0 hours later, you again observe this satellite to be directly overhead. How far above the earth's surface is the satellite's orbit...
1. Homework Statement
You hear the sonic boom of a high-speed jet plane exactly 4.50 s after it passes directly overhead in level flight. At the time you hear the boom, you see the plane at an angle of 16.0 o above the horizon. Assume that the speed of sound at the altitude of the plane is 325...
