P = Po + pgh

The equation above gives the total pressure , P on an object submerged in a fluid , where Po is the pressure at the fluid's surface , p is the density of the fluid , g is the acceleration due to gravity , and his the depth to which the object is submerged . What is h in terms of P , Po , , and g ?

A. pg / P - Po
B. P + Po / pg
C. P + Po + pg
D. P - Po / pg

Respuesta :

Answer:

D. h = ( P - Po ) / ρg

Explanation:

  • P = Po + ρgh

clearing h:

⇒ P - Po = ρgh

⇒ ( P - Po ) / ( ρg ) = h
