Answer:
Substances that dissolve most readily in water include ionic compounds and polar covalent compounds.
To solve for the new water level, let us first calculate
for the volume of the copper cylinder. The formula we can use is:
V = m / ρ
where V is the volume, m is the mass of the copper and ρ
is the density, therefore:
V = 48.85 g / (8.96 g / cm^3)
V = 5.45 cm^3
since cm^3 = mL
V = 5.45 mL
The new water level will be the initial volume of the
graduated cylinder plus the volume of the copper cylinder, therefore:
new water level = 20 mL + 5.45 mL
new water level = 25.45 mL
Answer:
Elctromagnetic waves can travel through empty space.
Explanation:
Waves that may pass through matter or empty space are known as electromagnetic waves. The electromagnetic field, like the other basic fields, penetrates the whole universe, including the region we refer to as empty space. There are no fields in space. The medium through which electromagnetic waves travel is called the electromagnetic field.
