Question

Given the densities of five objects: 2.00 grams/cm^3, 3.00 grams/cm^3, 4.00 grams/cm^3, 5.00 grams/cm^3, and 6.00 grams/cm^3. How many of these objects would float in water? A)1 B)2 C)3 D)4 E)0

Answer 1

Givne densities are,

`\begin{gathered} \rho_1=2\text{ g/}cm^3 \\ \rho_2=3\text{ g/}cm^3 \\ \rho_3=4\text{ g/}cm^3 \\ \rho_4=5\text{ g/}cm^3 \end{gathered}`

The density of water is ρ=1 g/cm³.

Any object will float if the denisty of the object is less than the density of water, if the density of object is greater than the dnesity of water, then the object sink in the water.

In the given case, all the objects have density greater than the density of water. Therefore, all the objects will sink in the water.

Thus, option E is corret, no object will flot on the water.
