77julia77 [94]

Answer:

V=200cm^3\\\\\rho =0.500g/cm^3

It will float.

Explanation:

Hello.

In this case, given the width, length and height, we can compute the volume as follows:

V=W*L*H\\\\V=4cm*5cm*10cm\\\\V=200cm^3

Moreover, since the density is computed via the division of the mass by the volume:

\rho =\frac{m}{V}

We obtain:

\rho =\frac{100g}{200cm^3} \\\\\rho =0.500g/cm^3

In such a way, since the solid has a lower density than the water, we infer it will float.

Best regards.

Someone please help! It is a few science questions. Fairly easy!
borishaifa [10]
1) 0.92 * 100 = 92 <Solve using the formula which is:
Mass=Density×Volume
M=D*V

2) 3.98 ml

3) V=L*W*H (Length  × Width × Height)

5*2*4=40
\frac{300}{40} =7.5 (Answer=7.5)

What class of solids is made up of regularly repeating subunits of tightly packed, orderly arrangements of atoms, ions, or molec
xxTIMURxx [149]
The answer is crystalline solid. Crystalline solids have a regular arrangement of particles, because of that, they possess definite geometry.
This means that if you take a look at the crystal under the microscope you would notice that there is a pattern that constantly repeats. This pattern is called a unit cell, and crystal is made up of stacked unit cells.
