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.

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.
![K.E = \frac{2KZe^2}{r}](https://tex.z-dn.net/?f=K.E%20%3D%20%5Cfrac%7B2KZe%5E2%7D%7Br%7D)
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>
![r = \frac{2KZe^2}{K.E} \\\\r = \frac{2 \times 9\times 10^9 \times 13\times (1.6\times 10^{-19})^2}{2.5 \times 10^6 \times 1.6 \times 10^{-19}} \\\\r = 1.5 \times 10^{-14} \ m](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B2KZe%5E2%7D%7BK.E%7D%20%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B2%20%5Ctimes%209%5Ctimes%2010%5E9%20%5Ctimes%2013%5Ctimes%20%281.6%5Ctimes%2010%5E%7B-19%7D%29%5E2%7D%7B2.5%20%5Ctimes%2010%5E6%20%5Ctimes%201.6%20%5Ctimes%2010%5E%7B-19%7D%7D%20%5C%5C%5C%5Cr%20%3D%201.5%20%5Ctimes%2010%5E%7B-14%7D%20%5C%20m)
<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
![r = \frac{2KZe^2}{K.E} \\\\r = \frac{2 \times 9\times 10^9 \times 13\times (2 \times 1.6\times 10^{-19})^2}{10 \times 10^6 \times 1.6 \times 10^{-19}} \\\\r = 1.5 \times 10^{-14} \ m](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B2KZe%5E2%7D%7BK.E%7D%20%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B2%20%5Ctimes%209%5Ctimes%2010%5E9%20%5Ctimes%2013%5Ctimes%20%282%20%5Ctimes%201.6%5Ctimes%2010%5E%7B-19%7D%29%5E2%7D%7B10%20%5Ctimes%2010%5E6%20%5Ctimes%201.6%20%5Ctimes%2010%5E%7B-19%7D%7D%20%5C%5C%5C%5Cr%20%3D%201.5%20%5Ctimes%2010%5E%7B-14%7D%20%5C%20m)
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.

Answer:
<em>No, the velocity profile does not change in the flow direction.</em>
Explanation:
In a fluid flow in a circular pipe, the boundary layer thickness increases in the direction of flow, until it reaches the center of the pipe, and fill the whole pipe. If the density, and other properties of the fluid does not change either by heating or cooling of the pipe, <em>then the velocity profile downstream becomes fully developed, and constant, and does not change in the direction of flow.</em>
