what is the dimensional formula for (i) variable force (ii) movement of force (iii) linear density (iv)angular momentum

plzzzzzzzzzzzzzzzzzzz ans as soon as possible

1)Force = Mass x Acceleration
Acceleration = Change in Velocity/Time Taken
Acceleration = M⁰L¹T^-2

Substituting this in Force formula we get
Force = Mass x Acceleration
Force = M x  M⁰L¹T^-2

So Dimensional Formula of Force= M¹L¹T^-2

3)Linear Mass Density is defined as measure of mass per unit of length.

Mathematically,
Linear Mass Density = Mass / Length.

Dimensional Formula of Mass = M¹L⁰T⁰.
Dimensional Formula of Length = M⁰L¹T⁰.

Putting these values in above equation we get,

Dimensional Formula of Linear Mass Density = M¹L^-1T⁰.

4)Angular Momentum is a product of Moment of Inertia and Angular Velocity. Its formula is
Angular Momentum = Moment of Inertia X Angular Velocity

Dimensional Formula of Moment of Inertia= M¹L²T⁰
Dimensional Formula of Angular velocity = M⁰L⁰T^-1

Putting these values in above equation we get

So Dimensional Formula of Angular Momentum = M¹L²T^-1
