Question

What defines our current ‘standard' for one meter? A The distance equal to 1/10,000,000 the distance between the Equator and North Pole b The length of a pendulum arm that takes 1 second to swing from left to right c The distance a 1 kilogram object travels in one second when acted on by a force of 1 newton d The distance light travels in a tiny fraction of a second

Answer 1

The distance light travels in a tiny fraction of a second

Step-by-step explanation:

One meter is defined as the length of the path travelled by light in a vacuum in
`(1)/(299 792 458)` of a second. It is also equal to the one
`(1)/(10)` of the distance from the equator to the North Pole. It is one of the fundamental units. It is a SI unit of length. So, the standard definition of 1 mete is the distance light travels in a tiny fraction of a second.

Hence, the correct option is (d).
