You have a meter stick marked to the nearest millimeter. which of these measurements is written with the correct amount of precision? a. 1.1 m b. 1.11 m c. 1.001 m d. 1,011.1 m

1.001 m

Explanation:

We have to find the least measurement of the instrument.

In this case the least measurement = 1 mm

                                                           = (1/1000) m

                                                           = 0.001 m

The measurement that is precise from this instrument should be to the nearest thousandth when taken in meters.

Therefore the answer is: 1.001 m

Answer

d. Optic fibers

Explanation

Air cannot be used to transfer information between computers. Although, radio waves are in air can be used as a medium of communication.

Glass and water cannot be used to transfer information between computers in their normal condition.

Fibre optic cables are special type of cables that are used to transfer information between computers efficiently. It is made by combining two grasses of different refractive index. It uses the concept of total internal reflection where the information is converted into light signal. The speed of information transfer is at speed of light(3.0 × 10⁸ m/s).

The best answer for the question above is d. Optic fibers
