For example a Helium-4 nucleus has two protons and two neutrons. The mass of the Helium-4 nucleus is less that the masses of two free protons and two free neutrons.
Crust
Explanation:
The crust is the layer of the earth with the least dense materials. The crust is made up of silicate materials.
- During the early stage in the formation of earth.
- The earth differentiated minerals based on their densities.
- Lighter minerals stayed afloat while the denser ones sank to the core of the earth.
- The core is made up of the most dense metallic minerals.
- As we go deep into the earth density increases.
- Density of crust ranges from 2.-3.3g/cm³
- The core is about 13.8g/cm³ dense.

The distance traveled by the student's boxcar that starts from rest and reaches an acceleration and velocity of 13.1 m/s² and 24.5 m/s, respectively, is 22.9 meters.
We can find the distance traveled by the boxcar with the following kinematic equation:
Where:
: is the final velocity = 24.5 m/s
: is the initial velocity = 0 (it starts from rest)
a: is the acceleration = 13.1 m/s²
d: is the distance =?
By solving the above equation for <em>d</em>, we have:
Therefore, the boxcar will travel 22.9 meters.

The first growth phase (G1): During the G1 stage, the cell doubles in size and doubles the number of organelles.
The synthesis phase (S): The DNA is replicated during this phase. In other words, an identical copy of all the cell’s DNA is made. This ensures that each new cell has a set of genetic material identical to that of the parental cell. This process is called DNA replication.
The second growth phase (G2): Proteins are synthesized that will help the cell divide. At the end of interphase, the cell is ready to enter mitosis.
