Fundamental And Derived Units

In a new system of units, the fundamental quantities mass, length, time are replaced by acceleration 'a', density 'rho', and frequency 'f'. The dimensional fromula for the force in this system is

Statement I: Fundamental units are the units for measuring fundamental quantities. Statement II: Metre is the unit of length.

If units of length, mass and force are chosen as fundamental units, the dimensions of time would be :

Which of the following have derived units ? (i) Mass (ii) Velocity (iii) Temperature (iv) Density

How many fundamental units are present in the SI system of units ?

If force (F) velocity (V) and time (T) are taken as fundamental units, then the dimensions of mass are
