About 30 seconds, I'm slightly claustrophobic.
Nuclear submarines can stay submerged indefinitely, some have stayed under for many months, the actual limits are classified.
the only limit is the food. Water and air are both manufactured from sea water. The fuel rods need replacing every 3-4 years. My brother in law was down 7 months once.

What are some features that all cats(cheetahs, lions, tigers, etc.) have?
1. Fur
2. Tongue is covered with horny papillae.
3. All have retractable claws except for cheetahs.
4. Have five toes on their forefeet and four on their hindfeet.
5. Large eyes for binocular vision
6. Presence of a tapetum lucidum which allows for excellent night vision.
7. Have vomeronasal organ on roof of mouth which allows for "tasting the air".
8. Possess highly sensitive vibrissa (whiskers).
9. Possess dental formula (except for Lynx): Top - 3.1.3.1, Bottom - 3.1.2.1
- Excellent hearing, eyesight, taste, and touch receptors
- Jacobson's organ in their mouths to enhance sense of smell
- Excellent balance
- Their whiskers help them "feel" their way around especially in the dark
- Big cats as well as domestic cats can purr
- Most cats sleep more than other mammals
- Territorial
- Carnivorous
- *Most* cats have tails, but some are tailless (such as the Manx)
All felines have a predatorial instinct.. i.e. they will give chase if one attempts to flee. This is true, but on certain levels,. I mean, if you run away from your pet cat it may not chase you! however, if a rodent tries to escape from your pet cat, well that could prove my point.
I love the cat family. They are all soooo gorgeous.
They all have whiskers, good hunting abilities, fur,
pricked up ears and beautiful eyes.
All mammal carnivores have carnassial teeth (slicing molars) and those of felines are the most advanced with scissor-like action. Check your cat's teeth--but VERY carefully.
Tails: different lengths
Claws: but not all can retract
Fur: different lengths, textures and colors
Carnivore: eat meat
Vision: can see great in the dark

How to give an anxiety attack to someone ?
like how to scare people :D
If you have actually had an anxiety attack yourself you wouldn't try to put one on someone else. Anxiety attacks can be very very serious.
Everyone hasn't a different threshold for what scares them. A minor "scare" is achieved with startling someone with something unexpected. I wouldn't try to purposefully induce an anxiety attack in someone as the heart palpitations have sent people to hospitals.
If you're a girl and you've had sex with them, tell them you're pregnant and you think it's theirs.
Put them in a barrel and tell them to stand in the corner.

The hawaiian islands are associated with.......volcanism?
a. intraplate
b. spreading plate
c. subduction zone
d. intercrustal
e. geothermal
Intraplate.
For one the prefix intra means inside, and two intraplate volcanism is that occurring in hot spots caused by the stretching or abnormalities in the plates.
Yellowstone and the geysers are other examples of intraplate volcanism.
I would say intercrustal as Hawaii isn't actually near a plate boundary it is positioned over a hot spot.

Chemical engineering question?
Hi, I im 14 and almsot 15 and im in year 9 at highschool, I was thinking about doing chemical engineering, Im disapointed because I got off to a bad start in science this year, But i was really good last year.
I am not that awesome at math, But im willing to get better, how much math is used in chemical engineering? What is involved in chemical engineering?
What is the average day like for a chemical engineer?
Also, whats the difference between a chemistry degree and a chemical engineer?
Are chemical engineers going to be needed in the future? say 10 years from now?
Also, is it to late for me to get better at science and math? Im in year 9, is it a lost hope? or can i still do it?
People are always asking what is a chemical (or mechanical or civil) engineer's day like. The truth is there is no simple answer to that question. You can ask a dozen chemical engineers and you will probably get 12 different answers.
As to the difference between chemistry and chemical engineering, they are poles apart. To most people your age chemistry is mixing stuff together to get a reaction. Chemical engineering is much much more complex than chemistry. I think most chemists think in laboratory terms. Chemical engineers think and are involved in much larger terms and more complex operations.
Will chemical engineers be needed in the future. Who knows for sure which engineering discipline will be "hot" ten years from now. I do know all engineering disciplines will always be needed and a good engineer will always be able to find a good job.
Now about being good in math and science. Are your problems related to not understanding the principles or just not doing the work to get good grades? Not doing the work is one thing but if you really don't understand the principles then you may need to think of another career path. In engineering understanding the principles is much more important than doing the math. Today so much of the calculations are built into computer software that understanding what you are doing is much more important than being able to crank out the numbers.
My degree is in mechanical engineering but I had two chemical engineers for room mates in college so I have a pretty good idea of what their study requirements were. After graduation I have worked with many chemical engineers and have even learned a good deal of chemical engineering my self. It can be a very interesting career.

Explaining what happens when we burn magnesium metal?
Task:
Explain what happens when
magnesium burns.
Top Tips:
?Try to use particle
diagrams to show what is
happening.
basically the magnesium oxidizes, which means it reacts with the oxygen in the air, you would need to show that when the magnesium is burned it reacts with oxygen to creat magnesium oxide, the really smelly white stuff :P
At room temperature, a sample of pure magnesium metal combines with oxygen to form a thin skin of magnesium oxide. At higher temperatures, it burns with a blinding white light, and because of this property it's used in fireworks.
It makes a chemical reaction. It's goes all sparkly.

How will planting trees help our environment?
I have to answer this question for school "what you think YOUR neighborhood could do involving plants and trees and landscapes to better or enrich your community."
Well I had the ideas of carpooling so that we will pollute less gas into the air. And to plant more trees, but I don't know an explanation WHY planting trees would be helpful to our environment. 10 points for good answer!
Trees give off oxygen which combats CO2 in our environment, which contributes to depleting the ozone layer. Oxygen fights this and makes our air more breathable and healthy.

Who gets National Youth Leadership Forum On Medicine. Is it for everyone?
Only for those with more money than sense. It's an overpriced vacation. Not an honor. Sorry.
Are cheetahs bilateral or radial symmetry? Are they asymmetrical?
Are cheetahs bilateral or radial symmetry? Are they asymmetrical?
cheetas definetly do not have radial symmetry, since it is not shaped like a starfish or sea anemone. It seems to have more of a bilateral symmetry. When dealing with symmetry in animals, shape and size matters, but not color, so the spots do not matter
they are bilaterally symmetrical; having said that they are so inbred because they are so few that some have an asymmetric face which is a hallmark of inbreeding.
Cheetahs are Asymmetrical.

How does cheetahs reproduce, sexually or asexually?
cheetas reproduce sexually, involving 2 members of the same species combining their genomes to form offspring, not using conjugation(kinda sexual, but happens on unicellular levels), budding, or binary fission
Cheetahs are mammals; all mammals reproduce sexually.
