<h3>(c) Terylene fibres</h3>
Explanation:
<h3>TERYLENE FIBRES </h3>
- Terylene Fibres is a crease-resistant, long-lasting material with a low moisture content. Pests like as moths and mildew have no effect on it. As a result, it's utilized to make fabrics that can be washed and wear clothes. It's also mixed with cotton (Terycot) and wool (Terywool) to add durability.
The density of a rectangle : ρ = 0.372 g/cm³
<h3>Further explanation</h3>
Given
The volume of rectangle : 395 cm³
Mass : 147 g
Required
The density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 147 g : 395 cm³
ρ = 0.372 g/cm³
