. A flip-flop stores a single bit (binary digit) of data; one of its two states represents a "one" and the other represents a "zero" Flip-flops can be divided into common types: the SR ("set-reset"), D ("data" or "delay"), T ("toggle"), and JK types are the common ones. The behavior of a particular type can be described by what is termed the characteristic equation, which derives the "next" (i.e., after the next clock pulse) output, Qnext in terms of the input signal(s) and/or the current output, Q.

Any fresh & energetic person who can teach Physics, Chemistry, Mathematics & Biology; can send their cv to us. We have three branches in west bengal; In Kolkata & Barrackpore, its running in full swing and in Chandannagor, we are going to open very shortly. Please see our page for any references required.

The magnitude of a magnetic force ‘F’ acting on charge ‘q’ when it moves with a velocity ‘v’ through a magnetic field ‘B’ is given by __________. (F = qvBsinq, F = qv2Bsinq, vBsinq, None of these)

Zero was known to Indians well before others. An ancient indian astronomer named ARYABHATT have discovered zero for his complex astronomical calculation. Arabs were responsible to introduce zero from india to Europe. Rules of Brahmagupta The rules governing the use of zero appeared for the first time in Brahmagupta's book Brahmasputha Siddhanta (The Opening of the Universe), written in 628 AD. Here Brahmagupta considers not only zero, but negative numbers, and the algebraic rules for the elementary operations of arithmetic with such numbers. In some instances, his rules differ from the modern standard. Here are the rules of Brahmagupta The sum of zero and a negative number is negative. The sum of zero and a positive number is positive. The sum of zero and zero is zero. The sum of a positive and a negative is their difference; or, if their absolute values are equal, zero. A positive or negative number when divided by zero is a fraction with the zero as denominator. Zero divided by a negative or positive number is either zero or is expressed as a fraction with zero as numerator and the finite quantity as denominator. Zero divided by zero is zero. Aryabhatta of India, he also discovered the decimal system - he was a great scientist of his time, most others would say Arabs, but they don't know thay Aryabhatta taught them. You know that there are 2 numeral systems-roman numerals and arab numerals but you would be surprised that it is actually India who invented the Arab system, Arabs are given the credit because they taught all our information to Europe but said that they invented this. system.

Brahmagupta, around 650 AD, was the first to formalize arithmetic operations using zero. He used dots underneath numbers to indicate a zero. These dots were alternately referred to as 'sunya', which means empty, or 'kha', which means place. Brahmagupta wrote standard rules for reaching zero through addition and subtraction as well as the results of operations with zero. The only error in his rules was division by zero, which would have to wait for Isaac Newton and G.W. Leibniz to tackle.
