The Cauchy number, Ca, describes the ratio of inertial force to compressibility force and can be written as; , where is density, is velocity and is the bulk modulus of elasticity. Using dimensional analysis, what are the correct units for bulk modulus of elasticity (expressed in basic dimensions)? Group of answer choices M L^-1 T^-1 M L^-2 T M L^-1 T^-2 M T^-1
