Use dimensional analysis to check if the expression p=(yv^2)/2 + ygh is correct. given that p is pressure in pascal, y is density in kgm^-3 , v is velocity in m/s, g is acceleration due to gravity in m/s^2 and h is the height in m(metre).

The expression is correct

Explanation:

We have the following expression:

Where:

Pressure: in units of Pascal ()

Density: in units of

Velocity: in units of

Acceleration due to gravity: in units of

Height: in units of

Knowing this, let's begin with the dimensional analysis:

Remembering , we are able to know this expression is correct.

answer: c.

explanation: the answer is c
