A wooden block has a mass of 20 g and dimensions of 5 cm x 1 cm x 1 cm.
marta [7]

Answer:

V = 5 cm³

ρ = 4 g/cm³

Explanation:

Step 1: Calculate the volume (V)

We have a wooden cuboid of dimensions 5 cm × 1 cm × 1 cm. We can calculate its volume using the following expression.

V = 5 cm × 1 cm × 1 cm

V = 5 cm³

Step 2: Calculate the density (ρ)

The density is equal to the mass divided by the volume.

ρ = m / V

ρ = 20 g / 5 cm³

ρ = 4 g/cm³

<h3>Hey Mate Here Is Your Answer:-</h3>

<h3>C- Diffusion</h3>

Reason:- The Mechanism of Diffusion In the case of food coloring in water, the water is the solvent while the food coloring is the solute. Once they've mixed, they make a solution. Diffusion takes time, though how much time depends on the kinetic energy of the molecules randomly bouncing among each other.

Ksivusya [100]

Answer:

The volume of a ball that is 24 cm across is :

d). v = four-thirds pi 12 cubed

Explanation :

Ball is a sphere and volume of sphere is given by :

\frac{4}{3}\Pi r^{3}

r = radius of ball

r =\frac{24}{2}

r = 12 cm

Volume is :

\frac{4}{3}\Pi \times 12^{3}
