Percentage error in length measurement = (0.1/5)×100 = 2%
Percentage error in width measurement = (0.1/2)×100 = 5%
 
Hence percentage error in perimeter = (2+5) = 7%
 
hence perimeter = [ 14± (7% of 14) ] cm = 14±0.98 cm  
 
perimeter is ranging from 13.02 cm to 14.98 cm
 
Hence (A) 13.6 cm to 14.4 cm includes the range of possible values of perimeter

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
