Answer:

PLS MARK ME AS BRAINLIEST

Explanation:

The need for reference of reliable scholarly source in academic writing (i.e. project) is to provide guide needed to confirm the writing of the scholar and to ascertain the writing are clear of plagiarism.

In academic writing, writers are required to state out the list of sources of information because:

1)To confirm authenticity of the writing

2)To prevent future plagiarism claim from the scholar.

3)To provide guide on how to trace the scholar writing

4)To complete the requirement of good academics writing

In conclusion, providing reliable scholarly source is the backbone of writing a perfect academics article, journal inclusive.

Explain in terms of energy flow how a cold pack works on a sprained ankle

sergij07 [2.7K]

The <span>flow of how a cold pack works on a sprained ankle is based on the second law of thermodynamics which states that energy will flow from a higher to a lower temperature. So your body heat will flow to the cold pack in which you will feel the coldness of the pack.</span>

Glycerin is poured into an open U-shaped tube until the height in both sides is 20cm. Ethyl alcohol is then poured into one arm

Liula [17]

Answer:

7.5 cm

Explanation:

In the figure we can see a sketch of the problem. We know that at the bottom of the U-shaped tube the pressure is equal in both branches. Defining $\rho_A:$ Ethyl alcohol density and $\rho_G:$ Glycerin density , we can write:

$\rho_A\times g \times h_1 + \rho_G \times g \times h_2 = \rho_G \times g \times h_3$

Simplifying:

$\rho_A\times h_1 = \rho_G \times (h_3 - h_2) (1)$

On the other hand:

$h_1 + h_2 = \Delta h + h_3$

Rearranging:

$h_1 - \Delta h = h_3 - h_2 (2)$

Replacing (2) in (1):

$\rho_A\times h_1 = \rho_G \times (h_1 - \Delta h)$

Rearranging:

$\frac{h_1 \times (\rho_A - \rho_G)}{- \rho_G} = \Delta h$

Data:

$h_1 = 20 cm; \rho_A = 0.789 \frac{g}{cm^3}; \rho_G = 1.26 \frac{g}{cm^3}$

$\frac{20 cm \times (0.789 - 1.26) \frac{g}{cm^3}}{- 1.26\frac{g}{cm^3}} = \Delta h$

$7.5 cm = \Delta h$

Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelen

Marta_Voda [28]

Answer:

a) that laser 1 has the first interference closer to the central maximum

c) Δy = 0.64 m

Explanation:

The interference phenomenon is described by the expression

d sin θ = m λ

Where d is the separation of the slits, λ the wavelength and m an integer that indicates the order of interference

For the separation of the lines we use trigonometry

tan θ = sin θ / cos θ = y / x

In interference experiments the angle is very small

tan θ = sin θ = y / x

d y / x = m λ

a) and b) We apply the equation to the first laser

λ = d / 20

d y / x = m d / 20

y = m x / 20

y = 1 4.80 / 20

y = 0.24 m

The second laser

λ = d / 15

d y / x = m d / 15

y = m x / 15

y = 0.32 m

We can see that laser 1 has the first interference closer to the central maximum

c) laser 1

They ask us for the second maximum m = 2

y₂ = 2 4.8 / 20

y₂ = 0.48 m

For laser 2 they ask us for the third minimum m = 3

In this case to have a minimum we must add half wavelength

y₃ = (m + ½) x / 15

m = 3

y₃ = (3 + ½) 4.8 / 15

y₃ = 1.12 m

Δy = 1.12 - 0.48

Δy = 0.64 m
