How do Submarines Work?

-
Submarines are vessels that can travel underwater. When the submarines want to dive in, its ballast tanks are filled with water making it heavier than the amount of water needed to fill the space taken by the submarine. Once it is submerged, the hydroplanes are adjusted to control the angle of dive. When it reaches the right depth, the hydroplanes are set to horizontal. To rise to the surface, the hydroplanes are set to direct upwards.

Communism

C ommunism A political ideology which has as its central principle the communal ownership of all property, and thereby the abolition of private property. Modern communism is specifically associated with the theories of Karl Marx , who saw the emergence of a communist society as being the final stage in a historical process that was rooted in human material needs, preceded by feudalism, capitalism , and (a transitional stage) socialism. Communism, according to Marx, would abolish class distinctions and end the exploitation of the masses inherent in the capitalism system. The working class, or proletariat, would be the instrument of a revolution that would overthrow the capitalist system and liberate human potential. The Communist Party of the Soviet Union (CPSU), first of all under Lenin's leadership and followed by Stalin, reinterpreted Marxist ideology as Marxism-Leninism-Stalinism, the major feature of which is democratic centralism. The CPSU provided the ideological lead for ...

The bright blue sky hides them from our visibility and when the Sunsets, the blue fades away making the stars visible. This blue is caused by the atmosphere.

How will the Universe End?

No one has been able to predict the future of the Universe. It could continue as such or eventually slow down, come to a halt and fly inwards to the “Big Crunch'. The astronomers believe that the future of the Universe depends upon the amount of material it contains. The greater the amount of material, the more powerful is the gravitational force trying to pull the galaxies back together. However, the galaxies known to us do not seem massive enough to end the expansion of the universe. But they could have hidden mass which would eventually slow down and end the present expansion.

What is Known About Mercury?

-
Image
Mercury is the innermost planet of our Solar System and has been once visited by a spacecraft , Mariner 10 in 1974. Photographs show Mercury to be atmosphere less and cratered, much like our Moon. Mercury's weak gravity cannot hold on to any gas to form an atmosphere. It rotates much slower than the Earth and takes two months to pass from sunrise to sunset. Being nearer to the Sun, it's day temperature reaches 4500C while the long nights are icy cold with the temperature of- 1700C. It is believed that a huge body must have crashed into Mercury several thousand million years ago causing a circular area 1,300 Km across, known as the Coloris Basin. Mercury has a very elliptical orbit around the Sun. It's distance from the Sun changes from 70 million Km when farthest away to only 46 million Km when nearest.
