Question

The dimension of A in expression
A(displacement) is similar to
(work)- mass
(1) Velocity
(3) Power
(2) Density
(4) Pressure​

Answer 1

Answer:

Dimension : Dimensions of the derived unit may be defined as the powers to which the fundamental units of the mass, length and time etc must be raised to represent that unit.

Example : speed = distance / time

= [ L ] / [ T ]

= [ M0LT-1 ]

Here speed is said to be possessed zero dimension in mass , 1 dimension in length and (-1) dimension in time

Force = mass * acceleration

=[MLT-2]

Here, force is said to possess one dimension in mass , one dimension in length and (-2) dimension in time

Answer 2

Velocity is correct option because dimensions is same
