Answer:
Business Model
Explanation:
A business model is basically a plan of how a business will make a profit. It indicates what type of services or goods they will deliver, who they will provided services to, and the expenses to expect.
A good business model can be used to attract investors, motivate staff and management and recruit potential talent into the business.
228 - 224 = 4
there is 4g of solute in the solution.
The representation of this problem is shown in Figure 1. So our goal is to find the vector
![\overrightarrow{R}](https://tex.z-dn.net/?f=%5Coverrightarrow%7BR%7D)
. From the figure we know that:
![\left | \overrightarrow{A} \right |=12m \\ \\ \left | \overrightarrow{B} \right |=20m \\ \\ \theta_{A}=20^{\circ} \\ \\ \theta_{B}=40^{\circ}](https://tex.z-dn.net/?f=%5Cleft%20%7C%20%5Coverrightarrow%7BA%7D%20%5Cright%20%7C%3D12m%20%5C%5C%20%5C%5C%20%5Cleft%20%7C%20%5Coverrightarrow%7BB%7D%20%5Cright%20%7C%3D20m%20%5C%5C%20%5C%5C%20%5Ctheta_%7BA%7D%3D20%5E%7B%5Ccirc%7D%20%5C%5C%20%5C%5C%20%5Ctheta_%7BB%7D%3D40%5E%7B%5Ccirc%7D)
From geometry, we know that:
![\overrightarrow{R}=\overrightarrow{A}+\overrightarrow{B}](https://tex.z-dn.net/?f=%5Coverrightarrow%7BR%7D%3D%5Coverrightarrow%7BA%7D%2B%5Coverrightarrow%7BB%7D)
Then using
vector decomposition into components:
![For \ A: \\ \\ A_x=-\left | \overrightarrow{A} \right |sin\theta_A=-12sin(20^{\circ})=-4.10 \\ \\ A_y=\left | \overrightarrow{A} \right |cos\theta_A=12cos(20^{\circ})=11.27 \\ \\ \\ For \ B: \\ \\ B_x=-\left | \overrightarrow{B} \right |cos\theta_B=-20cos(40^{\circ})=-15.32 \\ \\ B_y=-\left | \overrightarrow{B} \right |sin\theta_B=-20sin(40^{\circ})=-12.85](https://tex.z-dn.net/?f=For%20%5C%20A%3A%20%5C%5C%20%5C%5C%20A_x%3D-%5Cleft%20%7C%20%5Coverrightarrow%7BA%7D%20%5Cright%20%7Csin%5Ctheta_A%3D-12sin%2820%5E%7B%5Ccirc%7D%29%3D-4.10%20%5C%5C%20%5C%5C%20A_y%3D%5Cleft%20%7C%20%5Coverrightarrow%7BA%7D%20%5Cright%20%7Ccos%5Ctheta_A%3D12cos%2820%5E%7B%5Ccirc%7D%29%3D11.27%20%5C%5C%20%5C%5C%20%5C%5C%20For%20%5C%20B%3A%20%5C%5C%20%5C%5C%20B_x%3D-%5Cleft%20%7C%20%5Coverrightarrow%7BB%7D%20%5Cright%20%7Ccos%5Ctheta_B%3D-20cos%2840%5E%7B%5Ccirc%7D%29%3D-15.32%20%5C%5C%20%5C%5C%20B_y%3D-%5Cleft%20%7C%20%5Coverrightarrow%7BB%7D%20%5Cright%20%7Csin%5Ctheta_B%3D-20sin%2840%5E%7B%5Ccirc%7D%29%3D-12.85)
Therefore:
![R_x=A_x+B_x=-4.10-15.32=-19.42m \\ \\ R_y=A_y+B_y=11.27-12.85=-1.58m](https://tex.z-dn.net/?f=R_x%3DA_x%2BB_x%3D-4.10-15.32%3D-19.42m%20%5C%5C%20%5C%5C%20R_y%3DA_y%2BB_y%3D11.27-12.85%3D-1.58m)
So if you want to find out <span>
how far are you from your starting point you need to know the magnitude of the vector
![\overrightarrow{R}](https://tex.z-dn.net/?f=%5Coverrightarrow%7BR%7D)
, that is:
</span>
![\left | \overrightarrow{R} \right |= \sqrt{R_x^2+R_y^2}=\sqrt{(-19.42)^2+(-1.58)^2}=\boxed{19.48m}](https://tex.z-dn.net/?f=%5Cleft%20%7C%20%5Coverrightarrow%7BR%7D%20%5Cright%20%7C%3D%0A%5Csqrt%7BR_x%5E2%2BR_y%5E2%7D%3D%5Csqrt%7B%28-19.42%29%5E2%2B%28-1.58%29%5E2%7D%3D%5Cboxed%7B19.48m%7D)
Finally, let's find the <span>
compass direction of a line connecting your starting point to your final position. What we are looking for here is an angle that is shown in Figure 2 which is an angle defined with respect to the positive x-axis. Therefore:
</span>
Answer:
t< 75 nm
Explanation:
A soap bubble is a thin film where when the beam enters the film it has a 180º phase change due to the refractive index and the wavelength changes between
λ = λ₀ / n
In the case of constructive interference in the curve of the spherical film it is
2 nt = (m + ½) λ₀
Where t is the thickness of the film and n the refractive index that does not indicate that we use that of water n = 1.33, m is an integer. The thickness of the film for the first interference (m = 0) is
t = λ₀ / 4 n
A thickness less than this gives destructive interference.
Let's look for the thickness for the visible spectrum
Violet light λ₀ = 400 nm = 400 10⁻⁹ m
t₁ = 400 10⁻⁹ / 4 1.33
t₁ = 75.2 10-9 m
Red light λ₀ = 700 nm = 700 10⁻⁹ m
t₂ = 700 10⁻⁹ / 4 1.33
t₂ = 131.6 10⁻⁹ m
Therefore, for all wavelengths to have destructive interference, the thickness must be less than 75 10⁻⁹ m = 75 nm
b) a film like eta is very thin, it is achieved when gravity thins the pomp, but any movement or burst of air breaks it,
The cell theory states that:
1) All living organisms are composed of one or more cells.
2) The cell is the basic unit of structure and organization in organisms.
3) Cells arise from pre-existing cells.
Your statement is not present, so the answer would be no.
