Select all that apply

• Option A

  Newton treated compressions and rarefactions as isothermal.

• Option B

  Newton used the effective bulk modulus B = P.

• Option C

  Laplace treated the rapid changes as approximately adiabatic.

• Option D

  Laplace's corrected speed is √γ times Newton's value.
