Fruit colour in squash is an example of

Options

A. `4.6%`
B. `2.3%`
C. `9%`
D. `10%`

Answer

B

Explanation

`l=3.14 cm and Deltal=1mm=0.1cm," "T=(112.0)/(100)=1.12s and DeltaT=0.01s`
Formula for g is `g=4pi^(2)((l)/(T^(2)))," "(Deltag)/(g)=((Deltal)/(l))+2((DeltaT)/(T))`
`=((0.1)/(31.4))+2((0.01)/(1.12))=0.003+0.02=0.023`
Relative error in determining g is 0.23 and percentage error `=0.023xx100=2.3%`
