Question

which physical quantity has the dimensions (ml2 T-3)​

Answer 1

Answer:

Dimensional expression is .

here M denotes mass, L denotes length and T denotes time.

if we see all of these in SI unit,

Mass => Kg , Length => m and Time => sec

so, dimensional expression  converts into unit expression Kgm²/s³ .

as you know, unit of power is also kgm²/s³ .

[ power = energy/time = kgm²/s²/s = kgm²/s³ ]

so, given expression must be dimensional expression of power.
