simply divide 101325 by 760 i. e 101325/760 and u get ur answer

johnydon22:
Ok i will see to that then but just for the record am not a phone guru, dont really know how open a blog

Lol. .just to be fair, define spiritual. . . so we can grasp the exact notion you take it to imply

RobinHez:
hehe...u could start with blogger @ www.blogger.com or wordpress @ www.. Its pretty easy

like i said, we shouldnt do this here...we shouldnt do it at all sef

This is a science discussion thread. . . You made an assertion, you shouldn't try to shield it from healthy scrutiny and discussion, after all that's all science is all about; when you see a clue you follow it up. .

who knows, You might be the first person to prove that notion

johnydon22:
Ok will check it out then

6. Why havent we seen pictures of the objects left in the moon like the flag and the spaceships nd others
johnydon2

We have Am sure i mentioned it on my first reply about the satelite in orbit around the moon, all the 9 landings sites and objects have been spotted by the Lunar orbiter . . here read about it https://en.m.wikipedia.org/wiki/

Yeah probably need to see it again. . but have heard of plans to colonized Mars. .Mission MarOne. .i follow them on twitter too, they hope to send an unmanned craft to Mars by 2019 and a Manned mission by 2025. . google it up, i think i once opened a thread on that sometime ago here https://www.nairaland.com/2201801/possibilities-mars-colonization we can discuss that too
Right on spot
Hahahahaha

Mars colonization?
Okay, let's.
So, first, if we are to live on mars, a luxurious interplanetary transport system will need to be developed.
Meanwhile, there is a plan to build am elevator that goes from sea level to space. HERE is a link I found on that subject.

Also, there will be a need to terraform the host planet. In this case, mars, in my opinion, there are only two options. Either to build self contained pods on the surface on the planet . . . containing atmospheric air . . . or to change the atmosphere of the Entire planet itself! In that case' they will have to dissolve the needed oxygen in a very dense gas in order to prevent the atmosphere from escaping.
Also, people living on mars will be required to wear additional clothing containing heavy objects in order to make their weight equal to that of earth's. Otherwise, their bone tissue will atrophy and can fracture quite easily.

And then there is the obvious problem of getting water to the planet. I find this a formidable problem. For what are we to do? Are we to "fetch water" from earth and "pour" it on mars?
I think water has Been found at the poles of the planet, but it is not enough to regulate the planetal temperature. We have will have an excess temperature range of 25 degrees by day and -40 degrees by night

At this point, I would go with the pods. They would have to be fashioned like greenhouses. Containing heat trapping mechanisms. At least until greater technology . . . such as one that can. Defy the very natural process of an entire terrestrial ball.

Water would have to be constantly recycled. Although, at first, water will have to be harvested from the poles.

And then, in order to produce power, I suggest a fuel cell system. You might gun for nuclear power, but I say, why begin our sojourn on a strange planet by using such a bold and aggressive power source? there is already enough processes needing maintenance. We do not need to add a nuclear power plant to the already over flowing list!

Depending on if the planet turns out to have a hot core, geothermal power might also be considered.
I realize that by using a fuel system, am oxygen source will be needed. The result being that
The inhabitants of future mars colonies will have to compete with their own power source for oxygen! they will find this, I trust, rather interesting,
We can also manage a betavoltaic power source. But the technology has not yet been perfected. Even I am working on a prototype. Expect my research paper by 2017.

I am also currently working on a technology . . . it allows one to breath perpetually in a contained suit. Utilizing only electrical power. Expect the research paper on that by next year.
Back to the planet, I think the pods should be fashioned in such a way that they can be easily expanded with as little as possible reconstruction. But I trust NASA's engineers are not total idiots. They will see to that.
In order to keep the biosphere going, there will be need for food and water. This different from the water being used to bathe . . . or flush . . . it needs to be clean. As source of food, I recommend genetically modified foods. I know the possibility that they might not be healthy, but one can not eat his or her cake and have it. you cannot be among the first people to colonize a new planet, and still expect to compete with Methuselah.
So, plants that grow exceedingly fast, are disease resistant, and rather nutritious should be developed. I trust genetic engineers will have this taken care of.
As source of water, well, since the settlement is most likely to be located around the equator, and water is found at the planet's poles, they will have to devise a means of transporting water through extremely huge distances . . or perhaps, do you have another solution?
After years of playing sim city . . . . . . I have realized that in order to get humans to do whatever you need, you need to make them happy. There needs to be ways to entertain the humans there. Of course, they will have to go in pairs. Because . . . . konji I also recommend selecting only geniuses . . . as in individuals with IQs of above 130 these are considerably easier to satisfy. One only needs to provide a means of knowledge acquisition. Besides, they will be far more innovative than average intellects.

I suggest constant surveillance. HD and 3D in fact. That rubbish they did on the moon . . . not acceptable!
Watching the people on mars should be like watching a discovery world documentary. Clear, colorful, and acoustically optimal. . . don't you agree?
Of course, it takes about twenty minutes for the whole signal exchange to be completed. Well, we can deal with that. I guess . . .

I heard that NASA is planning to send just two people on the first mission. I strongly advice against this. We are speaking massive homesickness and a sense of being truly alone! I suggest at least four, if the technology we have cannot support it, well, recruit more brilliant engineers. We are plenty in naija. And we are all searching for jobs. also, they should recruit more billionaires for funding. Again, they should come to naija, I heard dangote wants to buy arsenal . . . it seems he doesn't know what to do with his fat account. Let's give him something.

Concerning waste on the planet. Poop, urine, used paper, onion skins . . . and so on, I suggest a full recycle operation where EVERY POSSIBLE THING is recycled. Compost, can be made from obvious sources, paper can also be recycled. In fact, if possible, the only thing not to be recycled will be the power.

In conclusion, I believe we can do this, we just need to take all factors into consideration. Also, more brilliant minds should be brought in. As well as more funding. I would even suggest that every university has a research section devoted to mars. And . . . . in twenty five years, you might just sit down to watch a program titled . . . "updates from the red planet."

Let's make this as interactive as possible, let all of us comment. Not just my Oga here,
I learnt that some people think we can never colonize the red guy. Where are you people? Come and talk. we dey here abeg.
Your two kobo needed.


Cheers!

samwayne154:
This is mine

Hmm!
I hope that isn't homework

Anyway, let's get on with it.

We are given, from your question,
Frequency =256
Length of tube =33.2

We are required to find v , velocity

However, there is a relationship between these values. Given as

f=v/4l. Where f is frequency, l is length, and of course, v is velocity which we are looking for.

At this point, we rearrange the equation to our satisfaction. In this case, we need v solitary on one side. We simply multiply both sides by 4l

Getting v = 4 x l xf

Substituting in given values,

v = 4 x 33.2 x 256

Allowing the calculator to work its magic,

v = 33996.8

It is then up to you to convert the above value, which is in cm/s to any unit you want.

I would go with 340m/s though




Cheers!

XploraBen:
Your submission on Mars colonisation is herculean,and would take several years before its workability becomes realistic.Though ideas such as yours can not be jettisoned because the advancement of future technology might handle it.


And as you rightly said,this project will require colossal amount of money--and as well as resources.More brainy scientists and astronauts will be needed...You can as well be part of 'em.

Well, I fear sometimes I get overly ideal.

Sure, they can recruit me. But only as a scientist though. I am not much of an astronaut.
Also, I don't expect any landing on Mars in this decade. While I believe we can achieve this within that time. We just need the right minds.

If only you were an American,you would have being noticed.You might probably be on your way to becoming a NASA scientist.Because for one thing,the whites appreciate brilliant and ingenious minds--just like yours.They don't allow ideas that will promote their lot to be punctured by the blunt edge of insouciance and flippancy.

LOL

Sir johnydon22. You are scarce here oh . . .

Meanwhile, there are many ways to get the attention of the americans one invention here, another scientific achievement there and they will beg you to come study in one of their universities.

That being said, I saw what you did there. all of us are brilliant. Not just me.

Hey bro, Have been a little busy with my stories. . . Anyway am here..

Will respond to your posts shortly. . . Anyway i have this idea of making a drone, need interested partners. . . Two heads are better than one and you know of course resources

Psylas:
present

welcome.

Teempakguy:
Alas! I googled marsOne. It would seem they have been wrapped up in a scandal recently. A link I found HERE is rather discouraging. Perhaps you can tell is your thoughts on this?

MarsOne to me now seems like a far fetched idea. . Their plans are poorly executed and to me there isn't much chance of the mission being a success. . .NASA has been planning a return trip to the moon since 2004 and due for 2019/2020. . Imagine that duration of a preparation just to get to the moon then imagine a manned trip to Mars.

If we are seeing any mission to Mars soon, i definitely think it would be NASA's planned mission for 2020 to launch Curiosity Rover's successor into the planet, For manned mission i anticipate NASA going there before this poorly planned MarsOne, Unless there is a secret agency planning this mission for many years now . .

Well, my own anticipation is that the first mars landing will be in 2030. And that by then, it will be easy to return.
It is just fifteen years from now. During that period, let the astrophysicists work.

Besides, I read that HALF of all missions to mars fails
Knowing this, I cannot help but think of the mars one mission as another dangerously planned fabrication that has a fifty percent of sending humans to the asteroid belt instead of mars.
Their last moments will be horrible.

But I agree with you. NASA has the best plan right now. . . that the public knows of.
About the drone, I recommend pakingzzz. I trust you know him?

Cheers!

Don't quite know the pakingzz guy

johnydon22:
The next launch of Curiosity Rover successor mission i think is the right trigger we need for NASA to develop a heightened interest to send humans to the red planet... Anyways a technology have been developed that can send scientist to Mars without them leaving earth, a blue print of them is generated on mars like a blueprint telephone call. . that way they can explore mars and research on it like they are there without not even crossing the comfort of their lab . . . But first the blueprint machine will be launched into Mars. . . .I hope curiosity rover will have like 5companions before 2025

Really? Is this like generating a clone? Or a humanoid robot linked to their brains? Is it on the internet? If so, please provide a link,

More than half of the missions if you ask me but none have been manned before. . . They had to come up with a drop method for the curiosity rover to be dropped on Mars which was successful. . . Have watched the documentary on t.v. . They had many disappointments

Don't quite know the pakingzz guy

Got that from Nasa official twitter account @Nasa . . . I follow mostly all their verified official accounts, From Nasa_Iss to even Curiosity rover to messanger and even astronauts . . . let me drop a picture i saved from the twitter. . this is a model of the machine

Ah, I have seen it. I do believe it is referred to as Hololens. From Microsoft.

Hololens . . . might actually have a lot of potential. Especially for engineers. Not just mars scientists.

In other news . . . chemists in the house, how would you separate a mixture of hydrogen and oxygen?

I will be back to mention you oh.

Teempakguy:

Frequency =256
Length of tube =33.2

all4naija:
What you termed as length of tube should be wavelength.

Velocity is frequency multiply by the wavelength(v = fλ) .

V = 265 x 33.2

V = 8,798 ≈ 880 m/s

Teempakguy:
adonbilivit!
If you are right, then it means, my physics teacher was wrong.
It also means that the speed of sound is 88m/s. Wikipedia disagrees with you on this. I think you are switching the formula for c=f/\ , speed of electromagnetc radiation, for v=4fl which is the velocity of sound in an open pipe.
They are quite unique.

Religion is an explanation. Just like science. It might it necessarily be a lie.
BTW, I have left a question above.
