Milk is an example of solid emulsion. Hence, option D is correct.
<h3>What is emulsion?</h3>
An emulsion is defined as a colloid consisting of two or more non-homogenous type of liquids in which one of the liquid contains the dispersion of the different form of liquids.
Emulsion consist of a dispersion of two liquids that are immiscible with each other.
One of the liquids act as the dispersion medium and the other will act as the dispersed phase.
Emulsions are colloids in which both the dispersed phase and dispersion medium are liquids.
Types of Emulsion:
- Oil in water (O/W)
- In this type of emulsion, the oil will be the dispersed phase and water will be the dispersion medium.
- Example of o/w emulsion is milk.
2. Water in oil (W/O)
- In this type, water will be the dispersed phase and oil will be the dispersion medium.
- Margarine is an example of water in oil emulsion.
Milk is an example of solid emulsion. Hence, option D is correct.

Answer:
Explanation:
Applying the Heisenberg uncertainty principle,
Δx X mΔv = h/4π
where Δx = uncertainty in measurement of position
Δv = uncertainty in measurement of velocity
m = mass of object
h = planck's constant
Here:
Δv = 0.4 A° = 4.0 x 10^-11 m
mass, m = 9.11 x 10^-31 Kg
Plugging the values,
4.0 x 10^-11 x Δ v = (6.626 x 10^-34) / (4 x 3.14 x 9.11E-31)
4.0 x 10^-11 x Δ v = 5.791 x 10^-5
Δv = 1.448 x 10^6 m/s, the uncertainty in its velocity
Answer = 1.45 x 10^6 m/s
The most abundant carbon isotope is carbon-12.
The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.
the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.
Answer is: mass of a single silver atom is 1.79·10⁻²² grams.
m(Ag) = 107.87 amu.
The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of one nucleon (1.66·10⁻²⁷ kg).
m(Ag) = 107.87 · 1.66·10⁻²⁷ kg.
m(Ag) = 1.79·10⁻²⁵ kg · 1000 g/kg.
m(Ag) = 1.79·10⁻²² g.
