The speed of sound in a gas depends on pressure p and density rho: v = kp^arho^b. Then

  1. a = 12, b = 12
  2. a = 1, b = -1
  3. a = - 12, b = 12
  4. a = 12, b = - 12
Answer

D) a = 12, b = - 12

LT^-1 = ( ML^-1T^-2)^a( ML^-3)^b: T: a = 12; M: a + b = 0: v = k p/rho. SLO P-11-A-04 · Application
