Physical changes: When a substance undergoes a physical change, it does not give rise to a different kind of substance or there is no new substance is formed. A physical change is a reversible change.
For example; heating of water melting of butter, cutting of paper etc.

Chemical changes: A Chemical change occurs when two or more chemical substances react to form new product that have an entirely different set of properties. A chemical change is mostly Irreversible. For example; cooking food, ripening of fruit, lighting a matchstick, aging of leaves and digestion of food etc.

Binary Number System: According to digital electronics and mathematics, a binary number is defined as a number that is expressed in the binary system or base 2 numeral system. It describes numeric values by two separate symbols; 1 (one) and 0 (zero). The base-2 system is the positional notation with 2 as a radix.

The binary system is applied internally by almost all latest computers and computer-based devices because of its direct implementation in electronic circuits using logic gates. Every digit is referred to as a bit.

Stars are celestial objects that can produce their own light. They are extremely hot and extremely large. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star; the sun’s energy and light play one of the key roles in sustaining all forms of life on earth.

Write a note on the military rule and democracy in pakistan

Posted by Ankita Saikia 5 years, 2 months ago (8850310)

CBSE > Class 12 > Political Science

1 answers

Meghna Thapar 5 years, 2 months ago (6237)

The military history of Pakistan encompasses an immense panorama of conflicts and struggles extending for more than 2,000 years across areas constituting modern Pakistan and greater South Asia. The history of the modern-day military of Pakistan began in 1947, when Pakistan achieved its independence as a modern nation.

The military holds a significant place in the history of Pakistan, as the Pakistani Armed Forces have played, and continue to play, a significant role in the Pakistani establishment and shaping of the country. Although Pakistan was founded as a democracy after its independence from the British Raj, the military has remained one of the country's most powerful institutions and has on occasion overthrown democratically elected civilian governments on the basis of self-assessed mismanagement and corruption. Almost none of the four military coups had a justified motive. Successive governments have made sure that the military was consulted before they took key decisions, especially when those decisions related to the Kashmir conflict and foreign policy. Political leaders of Pakistan are aware that the military has stepped into the political arena through coup d'état to establish military dictatorships, and could do so again.
