| The Ilyushin-76TD is the world's largest waterbomber | | The earth is getting hotter, and pretty quickly too. The 1990s were the warmest decade in a thousand years. In the next millennium, global temperature will increase between 3 and 6 degrees, which may create conditions that intensify wildfire danger, by warming and drying out vegetation, and by stirring the winds that spread fires. Fast fires are hard to contain, and likely to expand into residential areas. Already about 1 billion people live in areas prone to natural disasters.Fire Departments around the world now call on "waterbombers" to fight the fires. Carrying huge amounts of water and retardents, they actually are more cost-efficient than most other fire fighting methods.One of these waterbombers is the Erickson Helitanker. It can deliver 7,500 litres (2,000 gallon) of water in one drop, and refill from any water source 45 cm (18 inches) deep in about 45 seconds. The Helitanker can precision deliver 110,000 litres (30,000 gallons) per hour.Other aircraft are used too, such as the C-130, Martin Mars and DC-6. But the largest and fastest of the waterbombers is the turbofan jet Ilyushin-76TD (Il-76). It can reach a fire anywhere in the world within 12 hours.... | |
| | Do u think space research developing? (must readable one) | | Do u think space research developing?...I say yes bcoz nowa days lots of research going on in the space. do u think abt this?This is the question asked for the competition...I'm in the competition. I know some answers only...do u help me by solving this with rough work? Bcoz they need the rough work also...1 The luminosity of the Sun is 3.9 x 1033 ergs/sec (energy output per unit time). If the
radius of the Sun is 6.96 x 1010 cm and one assumes the Sun can be approximated
as a blackbody, choose the nearest effective temperature of the Sun from values
given below:
A] 5600 0K B] 5282 0K C] 5796 0K D] 6211 0K ANS:C2 What is the minimum rotational period of a star whose density is 108 g/cm3?
A] 9.4 s B] 1.2 s C] 0.1 s D] 81.5 s3 Crab nebula has a power law spectrum of the form dN/dE= 9.7 E- 2.1 photons/(cm2-
s-keV) where E is the energy of the photon. How many photons will a X-ray
detector operating in the energy range of 2-10 keV and geometric area of 30 cm2
detect in 100 seconds? (assume detector has 100% efficiency in this energy
range).

| | central nervous system | | The nervous system can be divided into several connected systems that function together.Let's start with a simple division:The nervous system is divided into the central nervous system and peripheral nervous system. Let's break the central nervous system and the peripheral nervous system into more parts.
Central Nervous System:
The central nervous system is divided into two parts:the brain and the spinal cord.The average adult human brain weighs 1.3 to 1.4 kg(approximately 3pounds).The brain contains about 100 billion nerve cells (neurons)and trillons of "support cells"called glia.The spinal cord is about 43 cm long in adult women and 45 cm long in adult men and weighs about 35-40grams.The vertebral column,the collection of bones (back bone)that houses the spinal cord is about 70 cm long.Therefore, the spinal cord is much shorter than the vertebral column. | |
| | your definition of sexy | | Hmm, I just read this news about a Korean Singer named Nara, her waist line it 18 inches (45 cm) and I'm not kidding. And people say that she is the new goddess, what do you think about this? Is waist line important in telling if someone is sexy? | |
