Physical quantity. → a quantity which can be measured and expressed in form of laws is called a physical quantity. physical quantity (q) = magnitude × unit = n × u. where, n = numerical value. u = unit. as the unit (u) changes, the magnitude (n) will also change but product ‘nu’ will remain same. i.e. nu = constant, or n 1 u 1 = n 2 u 2.

Solution: these type of question can be simply solved by putting the respective conversion units in the place. (a) 1kgm2s − 2 = 1 × 103g(102cm)2s − 2 = 107gcm2s − 2. (b) now we know that distance traveled by light in 1 year is called 1 light year. speed of light = 3 × 108 m s and 1 year = 365 × 24 × 60 × 60 s. The digits 2, 6, and 4 are significant figures. the number of significant digits is 3. (c) 0.2370 g cm–3 the value is 0.2370 g cm–3 for the given value with decimals, all the numbers 2, 3, 7, and 0 are significant. the 0 before the decimal point is not significant (d) 6.320 j all the numbers are significant. the number of significant.
