Acid Base And Salt Acid Acids:- The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour‚ such as curd‚ tamarind‚ lemon‚ etc. Types of Acids:- Acids are divided into two types on the basis of their occurrence – Natural acids and Mineral acids. Natural Acid:- Acids which are obtained from natural sources are called natural

Some say that the idea of love in modern terms differs conceptually from that of earlier periods. That argument is demonstrably false. Although love has been characterized in many different ways throughout the ages‚ the fundamental idea remains constant. No matter the eccentric personalities love is entitled to‚ love is what it is. From a literary point of view‚ whether one reads the tender longing of Sappho‚ the unattainable desire of Petrarch‚ or the whimsical prose of Dickenson‚ the message

1. Two ships P and Q are moving along straight lines with constant velocities. Initially P is at a point O and the position vector of Q relative to O is (6i + 12j) km‚ where i and j are unit vectors directed due east and due north respectively. The ship P is moving with velocity 10j km h–1 and Q is moving with velocity (−8i + 6j) km h−1. At time t hours the position vectors of P and Q relative to O are p km and q km respectively. (a) (b) (c) Find p and q in terms of t. (3) Calculate the distance

The quote above illustrates how Foucault claimed that being aware of constant surveillance created a sense of self-governance. Even tough there was not any set laws due to the fear Big Brother installed‚ the citizens of Oceania lived very precautious‚ uncertain of when or how they would break the law. Winston was constantly blocking out any thoughts not regarding big brother. The constant surveillance consequently created a sense of always policing themselves. Winston made sure he maintained a good
