Answer:
Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms
Each silicon atom shares its four valence electrons with the four Si atoms around it to create covalent bonds.
What is silicon atom?Silicon, a chemical element contained in sand and glass and denoted by the symbol "Si" in chemical formula expressions, is the most well-known semiconductor material utilized in electronic components. It has an atomic weight of 14. The most common isotope has an atomic weight of 28.
Silicon is a chemical element with the atomic number 14 and the symbol Si. A metalloid called silicon is a solid at ambient temperature.
One silicon atom contains fourteen electrons. In the ground state, they are arranged in the electron configuration [Ne]3s23p2. Four of them—four valence electrons—take up the 3s and 2p orbitals, respectively.
Thus, Each silicon atom shares its four valence electrons.

A 2. 0 kg particle moving along the x-axis experiences the force shown in (figure 1). The particle's velocity is 3. 0 m/s at x = 0 m.
Answer:
Explanation:
At point x = 0, the particle accelerates. Since there will be change of velocity at that point. The the force of the particle will change from negative sign to positive sign according to the given figure, we can therefore conclude that the particle will have a turning point at point x = 0.
Given that a 2.0 kg particle moving along the z-axis experiences the force shown in a given figure.
Force is the product of mass and acceleration. While acceleration is the rate of change of velocity. Both the force and acceleration are vector quantities. They have both magnitude and direction.
If the particle's velocity is 3.0 m/s at x = 0 m, that mean that the particle experience change of velocity at point x = 0. Since the the force of the particle will change from negative sign to positive sign according to the given figure, we can therefore conclude that the particle will have a turning point at point x = 0.

What is a segment?Segment, in general, refers to the pieces that any item is or may be divided into. For instance, a text, string, or other piece of data could be divided up into various chunks that could or might not be connected.
In other words, a line segment is a section or element of a line with two endpoints. A line segment, in contrast to a line, has a known length.
A line segment's length can be calculated using either metric measurements like millimeters or centimeters, or conventional measurements like feet or inches.
Division, fragment, member, part, piece, portion, and sector are some popular synonyms for segment. While all of these terms refer to "something less than the total," the term "segment" refers to a part that is divided or distinguished by, or appears to be, natural lines of cleavage.

Answer:
Explanation:
Given : Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. investment yields 2.7% simple interest annually,
To Find : how big was the initial deposit
Solution:
Let say investment in initial deposit = P $
Rate of interest R = 2.7 % annually
Time = 22 Years
Simple interest = SI
SI = P * R & T /100
=> SI = P * 2.7 * 22 /100
=> SI = 0.594P $
Investment worth = P + SI
= P + 0.594P
= 1.594P $
1.594P = 6774.50
=> P = 4250 $
initial deposit = 4250 $
