If the SI unit of mass is taken to be g
If the SI unit of distance is taken to be km
If the SI unit of time is taken to be s
What will be the expression for SI unit of intensity?

Options

A. `(g)/(s^2)km`
B. `(g)/(s^3)km`
C. `g//s^3`
D. `(km)/(s^3)`

Answer

C

Explanation

Intensity = `"Power"//"Area"`
`=((("mass"xx ("distance")/("time"^2))xxdistance)/("time"))/("distance"^2)`
`=("mass")/("time"^3)`
`=(g)/(s^3)`
