Name the SI unit of length and define it.​

Answer 1

Answer:

The science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products.

Answer 2

Answer:

the SI unit of length is meters.

1 meter is the “The length of the path travelled by light in a vacuum within 1⁄299792458 seconds.

now, this quantity is the fixed numerical value of the speed of light in vacuum .

which is approximately taken as 3 × 10⁸ m/ s.

we have a formula

speed = distance/ time

distance = speed × time

when speed = 299792458 m/ s

and time is 1/ 299792458 s

distance = 299792458 m/ s × 1/ 299792458 s

= 1 meter

Here, we understood the meaning of the definition too :}
