Question #2229a

Answer 1

I think the answer is option(3)....mass.

Explanation:

speed,length,mass,time.

Speed,length and time are mainly related to each other...but here mass is odd one...both the three are needed in one-dimensional motion but mass is NOT needed for one dimensional motion...

Hope it helps...
Thank you...

Answer 2

Speed

Explanation:

Length, mass and time are base quantities (also called fundamental physical quantities).

Speed is derived physical quantity.

`"Speed" = "Distance" / "Time"`
