- true or false. I- The speed of light in vacuum is a universal constant, whose value (without uncertainty, as it is defined as a standard) is c=299792458 m.s -1..The value of c in scientific notation is 2.99792458 x108 m.s-1. II- The value of c (velocity of light in vacuum) written to 3 significant figures is 3.00 x 108 .m.s-1. III- The value of the density of an object obtained was ρ±uρ=(7.768581114 ± 0.012540242) g.cm -3. The value obtained for the density and its respective uncertainty is incorrect, as it makes no sense to report the uncertainty with so many decimal places.
