Question

Name of physical quantities whose dimension formula are as follow :ML-1T-1

Answer 1

ML^-1T^-1 is the coefficient of viscosity.

check in ncert book class 11 last page where dimension formulas are given,
your doubts will be clarified if you check it once.

I hope it was helpful...

Answer 2

the physical quantities whose dimension formula are as follow :ML-1T-1 is viscosity.

1. viscosity is the force which opposes the flow of fluid (liquid and gas).
2. so it is basically the resistance of flow of fluid .
3. the unit of viscosity is poiseiulle (PI)
4. the main cause of viscosity is friction produced by the fluid during the flow.
5. he formula of viscosity =  force × time ÷ area.
6. it is denoted by the symbol η
7. so dimensional formula , η = [M1 L1 T-2] × [M0 L2 T0]-1 × [M0 L1 T-1]-1 × [M0 L1 T0] = [M1 L-1 T-1].
8. Therefore, viscosity is dimensionally represented as [M1 L-1 T-1].
