Suppose you have three objects of equal mass. the first object has a volume of 5 cm3 and is made of a material of density 2 g/cm3. the second object has a volume of 10 cm3 and is made of a material of density 1 g/cm3. what is the density rho of the material of the third object if its volume is 15 cm3?

2 g/cm³

Explanation:

m = Mass of object

v = Volume

ρ = Density

When ρ = 2 g/cm³ , v = 5 cm³

All the objects have same mass, which is 10 grams

When v = 5 cm³

Density of third object is 2 g/cm³

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
