Question

Which of the following is most precise measurement of the diameter of a wire

Answer 1

Answer:

The measurement 4.00 mm is most precise because it is measured with an instrument of minimum least count.

Answer 2

The complete question is

Which of the following measurements is most precise?

A) 4.00mm

B) 4.00cm

C) 4.00m

D) 40.00m

The correct answer is

option A) 4.00mm

The dimension 4.00 mm is most precise because it's measured with an instrument of minimal least count

• A screw hand is a perfect instrument. It's used for measuring the periphery of indirect objects substantially cables, with a delicacy of 0.001 cm.
• To calculate perfection using a range of values, start by sorting the data in numerical order so you can determine the loftiest and smallest measured values.
• Next, abate the smallest measured value from the loftiest measured value, also report that answer as perfection.
• A sovereign marked in millimetres is more precise than a sovereign marked only in centimetres since a millimetre is a lower unit than a centimetre.
• The closeness of two or further measures to each other is known as the perfection of a substance.
• If you weigh a given substance five times and get 3.2 kg each time, also your dimension is veritably precise but not inescapably accurate. Precision is independent of delicacy.
