Which of the following measured values has two significant f

Which of the following measured values has two significant figures?

Solution

L = 6.53 meters has three significant digits i.e. 6 at units place,5 at first decimal place and 3 at second decimal place

Hence this is not the correct option

L = 0.0522 meters has three significant digits

Hence this is not the correct option

L = 0.85 meters has two significant digits i.e. 8 at first decimal place and 5 at second decimal place

Hence this is the correct option

L = 0.8 meters has one significant digits i.e. 8 at first decimal place

Hence this is not the correct option

L = 0.06 meters has one significant digits i.e. 6 at second decimal place

Hence this is not the correct option

Therefore, the only correct answer is Option C (L = 0.85 meters)
