According to the rules for arithmetic operations with significant figures, the addition of the masses of 3 particles will be ? Q2) A quantity Q is formulated as 𝑋^(−2) 〖 𝑌〗^(+3/2) 〖 𝑍 〗^(−2/5) where X, Y and Z are independent parameters which have fractional errors of 0.1, 0.2 and 0.5, respectively in measurement. The maximum fractional error of Q is Q3) The maximum percentage error in the measurement of density of a wire is ? Given, mass of wire = (0.60 ± 0.003) g, radius of wire = (0.50 ± 0.01) cm, length of wire = (10.00 ± 0.05) cm. Q4) The energy of system is given as 𝐸(𝑡)= 𝛼^3 𝑒^(−𝛽𝑡), where t is the time and 𝛽=0.3 𝑠^(−1).The errors in the measurement of 𝛼 and 𝑡 are 1.2% and 1.6%, respectively. At t = 5 s, maximum percentage error in the energy is Q5) For an experimental expression 𝑦= (32.3 ×1125 )/27.4, where all the digits are significant. Then to report the value of 𝑦 we should write Q6) A physical quantity C is related to four other quantities 𝑝, 𝑞, 𝑟 and 𝑠 as follows: C = (𝑝𝑞^2)/(𝑟^3 √𝑠). The percentage errors in the measurement of 𝑝, 𝑞, 𝑟 and 𝑠 are 1%, 2%, 3% and 2%, respectively. The percentage error in the measurement of C will be ____________ % Q7) A physical quantity Q is related to four observables 𝑎, 𝑏, 𝑐 and 𝑑 as follows: Q = (𝑎𝑏^4)/𝑐𝑑 , where, 𝑎 = (60 ± 3) Pa; 𝑏 = (20 ± 0.1) m; c = (40 ± 0.2) N〖𝑠𝑚〗^(−2) and 𝑑 = (50 ± 0.1) m, then the percentage error in Q is 𝑥/1000 , where 𝑥 = _____________ .
