Which of the following solids will have the highest wave speed? one that has a high level of stiffness combines with low density - one that has a low level of stiffness combined with a low-density - one that has high level of stiffness combined with a high density - one that has low level of stiffness combined with a high density.

The first option (ONE THAT HAS A HIGH LEVEL OF STIFFNESS   COMBINED WITH LOW DENSITY)

Explanation: Low density means volume is high compare to mass and stiffness is about hardness

One that has a high level of stiffness combined with low density.

Explanation:

Velocity of wave in a solid = √ Y/σ ; Y is young's modulus of elasticity, or stiffness and σ is the density of the solid medium.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
