The advantages that can be associated to
drawings and symbols over written descriptions in engineering design and prototyping process are;
Communicate design ideas as well as technical information to engineers.
Symbols and drawings can be universal which means it is easy to interpret any where by professionals.
- An engineering drawing serves as complex dimensional object and symbol use by engineer to communicate.
- Drawings and symbols makes it easier to communicate design ideas and technical information to engineers and and how the process will go.
Therefore, drawings and symbols is universal to all engineer unlike written one.

The stance that a person will take on increasing the minimum wage is that higher earnings would boast the total standard of living for anyone that is earning minimum wage and it is one that can provide them with a lot of appropriate income level to manage the cost of living as it increases.
<h3>How would you validate your stance through research?</h3>
I will take a survey using a sample population of minimum wage workers and give them questionnaires to fill.
<h3>What are positive effects of reasons for raising the minimum wage?</h3>
- The merit of raising the minimum wage are:
- It boast or Improves employee in terms of retention.
- It also brings up the demand for goods and services.
- It tends to increase employee performance.
Therefore, The stance that a person will take on increasing the minimum wage is that higher earnings would boast the total standard of living for anyone that is earning minimum wage and it is one that can provide them with a lot of appropriate income level to manage the cost of living as it increases.

Answer:
Efficent at low speeds.
Explanation:
Since water is 1,000 times more dense than air, electricity can generated from tides much more efficiently at slower speeds than wind turbines can.
The thickness of aluminium needed to stop the beam electrons, protons and alpha particles at the given dfferent kinetic energies is 1.5 x 10⁻¹⁴ m.
<h3>
Thickness of the aluminum</h3>
The thickness of the aluminum can be determined using from distance of closest approach of the particle.
where;
- Z is the atomic number of aluminium = 13
- e is charge
- r is distance of closest approach = thickness of aluminium
- k is Coulomb's constant = 9 x 10⁹ Nm²/C²
<h3>For 2.5 MeV electrons</h3>
<h3>For 2.5 MeV protons</h3>
Since the magnitude of charge of electron and proton is the same, at equal kinetic energy, the thickness will be same. r = 1.5 x 10⁻¹⁴ m.
<h3>For 10 MeV alpha-particles</h3>
Charge of alpah particle = 2e
Thus, the thickness of aluminium needed to stop the beam electrons, protons and alpha particles at the given dfferent kinetic energies is 1.5 x 10⁻¹⁴ m.
