Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.
Given data:
Volume of calcite (V) = 15 cm³,
mass of calcite (m) = 40.5 g,
find the
density of calcite (ρ) = ?
density is defined as " it is the amount of matter of an object in a given volume". Simply it is the ratio of matter in an object to its volume. The unit of density is kg/m³ in SI system or g/cm³ in CGS system.
Mathematically,
density ( ρ) = mass/volume
= m/V g/cm³
= 40.5 g/15 cm³
= 2.7 g/cm³
Hence, the density of calcite is <em>2.7 g/cm³ </em>

I dont know the answer i just want brainy points<span />
Answer:
B. Does not compress under pressure
Explanation:
Brake fluids are fluids used to transmit the pressure applied from the brake pedals to the brakes. Fluids are used because they are not as compressible when compared to gases i.e., there is no loss of power when the pressure is applied.
Brake fluids are generally glycol-ether based. They do not corrode the metal parts and have a very high melting point.
