In 1970, there were less than 50 software companies in Smart City Software Park. The number of these software companies has changed over the years. Construct a time series graph for the data and comment on the findings. Year Software companies 1992 69 1993 79 1994 103 1995 112 1..

Another type of microphone, widely used in public-address systems, depends for its action on the piezoelectric effect possessed by certain crystals, for example Rochelle salt. The term piezoelectric effect refers to the fact that when pressure is applied on the crystal in the proper direction, ele..

. For this, we require a data-gathering system to map and monitor the urban sprawl. Remote sensing offers excellent possibilities in solving this problem. (11) A specialized application of remote sensing is in the field of defense, both for gathering intelligence information and..

Standard Deviation of a statistical data is defined as the positive square root of the arithmetic mean of the squared deviations of items from their arithmetic mean of the series under consideration. The standard deviation is denoted by s (sigma). The stand..

Linear equations/inequalities Monomials and polynomials Factoring second and third degree polynomials Rational expressions/functions Quadratic equations Quadratic functions Exponents, factors, variation, exponential growth/decay Hypothesis, counterexamples Correlation for data ..

Modems - The 'modem' is a contraction of the term modulator-demodulator. It is a conversion that facilitates the transmission and reception of the data over the public switched telephone network (PSTN). The data of interest may be digital signals generated by computers or servic..

The mean deviation of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of items from some average value. Mean deviation is also known as average deviation . The mean deviation is generally denoted by M.D. Formula for mean deviation for ungroup..

Different forms of numbers Scientific notation, square roots, exponents, radicals, absolute value, factorial, logarithms Properties of numbers Estimation of solutions Sequences and series Proportionality/direct variation, exponential/fractional expressions Patterns, relations and ..

Dilute sulphuric acid reacts with metals, which are above hydrogen in the activity series, producing the respective sulphate salt and hydrogen. Remember:- Though potassium, calcium and sodium react with sulphuric acid to form sulphate salt and hydrogen, they are never..
