World's Fastest Train__

Which is the world's fastest train?

France is the world leader in rail transport technology. The flagship of French rail technology is the TGV or Train a Grande Vitesse ("High Speed Train"), the world's fastest train. TGVs regularly run at 300 km/hr in normal service on some lines. And even this high speed is well below TGV's limits; the TGV holds world record for speed on rails of 515.3 km/hr or roughly half the speed of the sound.

Blood Clot?

How does the blood clot?

Clotting is a natural phenomenon tht checks excessive loss of blood in case of injury. Clotting takes place whenever the tissue is injured. There are three types of cells in our blood - red blood cells, white blood cells and platelets. It is these platelets that help in forming clots to stop bleeding. The platelets gather at the site of the injured cell and prevent the red blood vessels from flowing out. They form a plug across the opening and release chemicals that convert liquid blood protein fibrinogen into insoluble fibrin. Fibrin forms a mesh of thread like fibres that trap platelets and other blood cells, thereby forming a clot.

Difference between ballistic missile and cruise missle?

What is the difference between ballistic missile and cruise missile?

A ballistic missile is a missile that follows a prescribed course that cannot be significantly altered after the missile has burned its fuel (i.e., its course is governed by the law of ballistics). In order to cover large distances, ballistic missiles are usually launched very high into the air or in space.

*****

A cruise missile is a guided missile which uses a lifting wing and most often a jet propulsion system to allow sustained flight. Cruise missiles are, in essence, unmanned aircraft. They are generally, designed to carry a large conventional or nuclear warhead many hundreds of miles with excellent accuracy. Modern cruise missiles normally travel at subsonic speed, are self-navigating and fly low in order to avoid radar detection.
