Question 2

Question 3

Density formula

ρ = m/V
Where:
ρ is the density
m is the mass
V is the Volume.

Question 4

The unit of density is depended on what?

Answer 4

It is depended on the input units of the formula. For example:

• kg for mass and m³ for Volume => kg/m³
• g for mass and cm³ for Volume => g/cm³
• mg for mass and cm³ for Volume => mg/cm³

It is recommended to use kg/m³ and g/cm³, but it depends on the situation.

Question 5

Define buoyancy ( ͡° ͜ʖ ͡°)
