    a little inquiry! PHY

    well those 2 ansers are to 2 sig figures,,,bt wat i am saying is that the calculation u perform to reaach final ans...in those steps u should not round......it cn lead to big error..either carry forward value in calculator or use 4-5 d.p
  18. H

    a little inquiry! PHY

    hmm....the thing is that the final answer should be quoted to three sig. figure and the value used to calculate it should be carried forward on calculator ar 4-5 s.f of them shud be used....u mst not round them to 3 s.f and use rounded values to calculate final anser....hope that he;lps
