Answer:
0.92g/mL
Explanation:
Density of a substance is calculated as follows:
Density = mass (m) ÷ volume (V)
According to this question, a rectangular piece of plastic has a width of 4.2 cm, a height of 1.9 cm and a length of 8.8 cm. Using the formula; L × W × H, the volume of the plastic can be calculated
V = L × W × H
V = 8.8 × 4.2 × 1.9
V = 70.2cm³
The mass of the plastic is 64.6g, hence, its density is:
Density = 64.6g ÷ 70.2cm³
Density of the rectangular plastic = 0.92g/cm³ or 0.92g/mL
Answer:
I believe the answer is D
The Physical properties of Iron are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
Explanation:
Color Silver-gray metal
Malleability Capable of being shaped or bent
Ductility Easily pulled or stretched into a thin wire
Luster Has a shine or glow
Conductivity Good transmission of heat or electricity
Allotropy It occurs in two or more crystalline forms in the same physical state
Tensile It can be stretched without breaking
Ferromagnetic Easily magnetized
Which best depicts wind erosion?
B.
rolling marble
That statement is True
The components of a true solution consist of homogenous mixture which substance dissolved in a solvent. Later on, this components will blend with others and form new properties
hope this helps
