Question

Find dimension of pressure and momentum?​

Answer 1

Answer:

1)pressure=force/area

Dimension of force is [M^1 L^1 T^-2 ]as force is define as mass x acceleration.

dimension of area is [L^2].

So dimension of pressure is [M^1 L^-1 T^-2]

2)Momentum is define as mass x velocity

Dimension of mass is [M^1] and velocity is

[L^1 T^-1]

Therefore dimensions of momentum is

[M^1 L^1 T^-1].

Answer 2

Answer:

pressure=force/area

Dimension of force is [M^1 L^1 T^-2 ]as force is define as mass x acceleration.

dimension of area is [L^2].

So dimension of pressure is [M^1 L^-1 T^-2]

2)Momentum is define as mass x velocity

Dimension of mass is [M^1] and velocity is

[L^1 T^-1]

Therefore dimensions of momentum is

[M^1 L^1 T^-1].

∴[M^1 L^1 T^-1].
