Question

find the dimensions of following. 1)area 2)force 3) velocity 4) volume 5) speed​

Answer 1

1.[L^2]

2.[MLT^-2]

3.[LT^-1]

4.[L^3]

5.[L]/[T]

Answer 2

$\huge\mathfrak{Solution- }$

1. Area = l × b

= [L] × [L]

= [L]^2

2. Force = m x a

=[M] × [LT^-2]

=[MLT^-2]

3. Velocity = d/t

= [L]/[T]

=[LT^-1]

4. Volume = l × b × h

= [L] x [L] x [L]

=[L^3]

5. Speed = d/t

=[L]/[T]

=[LT^-1]
