Which one is venturi relation ?
  • (A)  P1 – P2 = 1/2 ρV22
  • (B)  V2 = 2g (h1-h2)
  • (C)  P = 1 /2ρV2 = ρgh = constant
  • (D)  A1 V1 = A2 V2 = constant
In vibratory motion_________________?
  • (A)  P.E. remains constant
  • (B)  K.E. remain constant
  • (C)  total energy remains constant
  • (D)  total momentum remains constant
