Studdy Solution
STEP 1
Assumptions1. The SI unit of length is being asked. The given definition is that the unit is equal to the distance light travels in a vacuum in of a second
STEP 2
We need to identify which of the given options (kilogram, meter, pound, second) is the SI unit of length defined as the distance light travels in a vacuum in of a second.
STEP 3
The kilogram is the SI unit of mass, not length, so option A is incorrect.
STEP 4
The meter is the SI unit of length, and it is defined as the distance light travels in a vacuum in of a second. So, option B is correct.
STEP 5
The pound is a unit of mass in the imperial system, not an SI unit of length, so option C is incorrect.
STEP 6
The second is the SI unit of time, not length, so option D is incorrect.
The correct answer is B. meter.
