Where does the kinetic energy go here? Posted: 26 Nov 2016 06:25 AM PST Imagine you and your buddy Neil Armstrong are in space. You both see a bunch of objects of different sizes and at different distances moving towards your direction, all of them around the same speed. From your frame you calculate the kinetic energy of all this particles. Then Neil pushes you while grabbing the spaceship, giving you the same speed and direction as this particles. From your new frame of reference all this stuff is standing still. The kinetic energy you can measure now is from the spaceship and from Neil which is less than the original. What happened with the energy? Where does it go? Or is energy relative? ...You then remember Neil has just double-crossed you and curse him at the top of your lounges while you descend into deep space submitted by /u/clumsywatch [link] [comments]

What is the brigthest planet as seen from another planet? Posted: 26 Nov 2016 03:14 AM PST I know that venus is the brigthest planet as seen from earth, but aside from the Sun and moons, can more brigth celestial objects be seen from other planets? I know few things that come into account when calculating this -Planets distance from the sun -Distance of planets between each other -Size of the planet -Reflectivesness of the planet -Possible relative allingments of the 2 planets and the Sun But its way above me to put all of them together. submitted by /u/empire314 [link] [comments]

Why are most all of the world's deserts sandy? Posted: 25 Nov 2016 09:25 PM PST Obviously when things like all of Antarctica are classified as a desert, not every single one is covered in sand.

How can we differentiate so many simultaneous sounds? Posted: 26 Nov 2016 07:11 AM PST So I understand that sound waves are vibrations in a medium; for example, a drum sends a wave of energy through the air that eventually vibrates the air molecules next to my ear drum, which is then translated into a recognisable sound by my brain, as opposed to actual air molecules next to the drum being moved all the way over to me. But if I'm listening to a band and all the instruments are vibrating that same extremely limited number of air molecules inside my ear canal, how is it that I can differentiate which sound is which? submitted by /u/duetschlandftw [link] [comments]

What property of a charged particle causes the charge? Posted: 26 Nov 2016 06:54 AM PST In other words, what is charge? What causes us to say; "Well okay, an electron has a negative charge and a proton a positive charge." submitted by /u/imRobert7 [link] [comments]

Why do some species have such enormous individual variation while others look pretty much all the same? Posted: 26 Nov 2016 06:01 AM PST Common Buzzards Buteo buteo for example have huge difference in colouring despite being the same species and subspecies, and there being no apparent geographic component to the variation. Two Buzzards in the same field can look so different a layperson wouldn't even think they're the same species. Yellow Wagtails Montacilla flava are known for having a large number of subspecies which all look different but are still considered the same species, here you can see that the different subspecies come from different places, indicating that the variation is a result of geographic distribution differences. In many cases it is possible to differentiate between a Yellow Wagtail from the Iberian peninsula from one from Italy from one from Sweden, for example, based on the way it looks alone. Osprey Pandion haliaetus however is one of the most widespread bird species in the world, but one from North America looks pretty much identical to one from Europe. What gives? submitted by /u/YoSoyUnPayaso [link] [comments]

What would happen if someone was placed inside a giant hollow cube with gravity being exerted uniformly by all 6 walls? Posted: 26 Nov 2016 05:21 AM PST Would the uniform gravity from all sides of the cube cancel out and result in zero-gravity?

Why does our tiny lump of rock that is Earth have so many different elements? Posted: 26 Nov 2016 07:15 AM PST It seems so unlikely, that our planet, which in the grand scale of the Universe is so tiny, that there is some of every single known element present. Surely it would be much more likely for a planet to consist of a few core elements? Does our variety of elements say anything about how our planet may have formed? submitted by /u/sim_sayer [link] [comments]

How to calculate Bessel function and its constants?

Since Chickenpox is a virus, doesn't stay in your system forever? If so, why don't children of adults who have had the virus immune to it? Posted: 25 Nov 2016 11:30 PM PST I'm under the assumption almost everybody eventually get chickenpox, most during their younger years.

How does radio stations transmit the name of the song currently broadcasted? Posted: 24 Nov 2016 08:21 AM PST Just noticed that my car audio system displays the name of the FM radio station, the song being played and its genre.

If you explain 3^2 as three multiplied by itself twice, how do you explain 3^-1 using the same language convention? Posted: 24 Nov 2016 07:32 PM PST E.g 32 = 3 x 3 31 = 3 31 = 1/3 As in, you can explain positive powers by saying the base multiplied by itself x number of times. But how do you explain negative exponents in the same way? Can you even? 3-2 isn't 3 x itself negative 2 times, it's just 1/32. How do you explain this using language?

How are inertial confinement fusion reactors fueled? Posted: 25 Nov 2016 03:34 AM PST I saw this comment from u/tminus7700 in a previous r/askreddit post: You just shoot the pellets machine gun style into the chamber and fire whatever energy to light them off as they arrive at the focal point. I tried to research further, but I didn't find anything on Google with the keywords "Inertial confinement fusion machine gun". If you want to use an inertial confinement reactor efficiently you want a method to refuel it without depressurising the reactor chamber to place the pellet. Anyone willing to provide further information? Thanks submitted by /u/Chasar1 [link] [comments]

Shouldn't time dilation be symmetric so that earth observers see an astronaut's 'clock' as running slower and vice versa?

When does a bullet reach its maximum velocity? Posted: 24 Nov 2016 03:29 PM PST I was wasting my time on youtube watching gun videos and this got me thinking. The bullet has to reach Vmax from standstill in some time, then is slows down due to air drag. It should be somewhere in the barrell, but is there a way to know when and where? Also is this related to the force the gun kicks back with? submitted by /u/Dredddddd [link] [comments]

With the advancements in technology in recent years, why does it seem that radio signals and the strength of signals have appeared to stay the same? Posted: 24 Nov 2016 06:51 PM PST I ask this because when I drive the truck for my work I listen to the radio, but when I get into the city it seems that the strength of the signal weakens and when I go in the tunnels it vanishes. This happens to all but two stations and most of the stations are within 10-25 miles to the city. Is it cause the city can cause the signals to weaken? Or do other stations using similar frequencies that can cause this to happen? Or is it a combination of things? submitted by /u/UncleBen94 [link] [comments]

Does the heat produced by combustion engines have an effect on Earth's temperature? Posted: 24 Nov 2016 07:44 PM PST Over Thanksgiving dinner my father and I were discussing climate change and the topic of heat generation came up. His argument is that since fossil fuels are essentially stored thermal energy, burning them is releasing that energy. A quick calculation says that all the cars in America produce enough heat each year to raise Lake Michigan's temperature by one degree Fahrenheit. So that energy has to go somewhere. I think he's missing something since we only hear about the effects of the chemical waste of engines and not the thermal waste. submitted by /u/PiLamdOd [link] [comments]

Is the false vacuum theory a common theory in the scientific world ? Posted: 24 Nov 2016 12:59 PM PST So today I learned of the existence of this theory, and from what I understood, in a very simple version it basically says that our universe as we perceive it is similar to a bubble and can suddenly burst at any moment, right ?

Why doesn't Raoult's Law depend on the chemical nature of solute? Posted: 24 Nov 2016 11:15 AM PST According to Raoult's Law, dissolving a solute into a solvent decreases the saturation vapor pressure. Being a colligative property, it doesn't matter what the chemical nature of the solute is, only how much there is. However we know that things like melting point and saturation vapor pressure (and by extension boiling point) depend on the strength of intermolecular forces. We say that a compound with stronger intermolecular forces has a lower saturation vapor pressure (i.e., is less volatile). My Question: If the solute being added to the solution causes there to be stronger intermolecular interactions, wouldn't this cause a lowering in saturation vapor pressure? If so, then the claim that Raoult's Law doesn't depend on the chemical nature of the solute is untrue. Can someone help me untangle this? TLDR: If saturation vapor pressure is defined by strength of intermolecular forces, why does dissolving a solute into a solvent lower saturation vapor pressure regardless of its chemical properties when we know for a fact that different solutes have different strengths of intermolecular forces with the solvent? submitted by /u/NewToUni [link] [comments]

Why does the polynomial x^5 - x + 1 = 0 have no exact solution? Posted: 24 Nov 2016 10:07 AM PST I just saw this old Vihart video that mentioned the fact that this polynomial only has an approximate solution, not an exact one. However, when I rearrange the equation into x4 - 1 = -1/x and graph the two individual functions (you can use this online graphing calculator to see), the "approximate" solution of -1.167... is where these two functions cross. Since they are both continuous, differentiable, and cross at this point, why is this only an approximate solution? submitted by /u/thomprya [link] [comments]

Does receptor downregulation change depending on the frequency of doses? Posted: 24 Nov 2016 11:20 AM PST In receptors that get downregulated through agonist application (I understand not all receptors do this).

Why is Iron more stable than Nickel even though it has a lower binding energy per nucleon? Posted: 23 Nov 2016 11:48 AM PST Im studying nuclear physics in school and we were looking at the binding energy per nucleon graph. The element becomes more stable as the binding energy per nucleon increases. So from the graph you can see that smaller elements carry out fusion, and larger elements fission, in order to become more stable. We were told that iron is the most stable element, however nickel has a higher binding energy per nucleon. Why is Iron more stable? submitted by /u/RavernousPenguin [link] [comments]

Are there any naturally-occurring large-scale organic materials that don't decompose? Posted: 23 Nov 2016 05:33 PM PST I know that in the Carboniferous, the ability to digest lignin hadn't been evolved yet, and that contributed to the vast coal beds laid down at the time.
