B) 120 cg/mL , because 1g = 100cg and 1L = 1000mL

Answer:

B. 120 cg/ ml

Explanation:

<u><em>If a liquid has a density of 1,200 g/L, what is its density in cg/mL?</em></u>

<u><em /></u>

To fin this, we will simply use the idea of proportion. But first we need to know the number of gram per liter  in 1 centigram per milliliter. Thus;

Let x = density of liquid in cg/ ml

1 cg/ml    = 10 g/l

  x          =  1,200 g/l

cross- multiply

10x =  1,200

Divide both-side of the equation by 10 to get the value of x

10x/10 = 1,200/10

(At the left-hand side of the equation, 10 on the numerator  will cancel-out 10  on the denomination and we will be left with just x, while on the right-hand side of the equation, 1200 will be divided by 1200)

x = 1,200/10

x =120 cg/ml

Therefore, the density of the liquid is 120 cg/ml

What happens when stress builds at faults? Select three options
Stels [109]

Answer:

When Stress builds up at faults, the 3 options that are correct and can happen

- Rock can bend and break;

- Earthquakes develop at Earth's surface

- Forces affect Earth's rocks

Explanation:

This is a Geography question

- Rock can bend and break

When Stress builds up at faults, it leads to a geologic activity that causes a lot of pressure that lead to the movement of the earth's crust. The movement creates such intense pressure on the rocks, that, with time, they twist, bend, and break due to this pressure.

- Earthquakes develop at Earth's surface

As explained earlier, this intense pressure can lead to rocks breaking, as these rocks break inside the earth's crust, the gaps that come into play after the breaking of the rocks causes the remaining rocks to adjust, releasing a lot of force, and subsequently creating earthquakes.

- Forces affect Earth's rocks

As explained earlier, the forces resulting from these intense pressures, affect the earth's rocks. They move them both vertically and horizontally, change their shape and eventually break them.

Hope this Helps!!!

A grating has 470 lines/mm. how many orders of the visible wavelength 538 nm can it produce in addition to the m = 0 order?
maria [59]

Three complete orders on each side of the m=0 order can be produced in addition to the m = 0 order.

The ruling separation is

d=1 / (470mm −1) = 2.1×10⁻³ mm

Diffraction lines occur at angles θ such that dsinθ=mλ, where λ is the wavelength and m is an integer.

Notice that for a given order, the line associated with a long wavelength is produced at a greater angle than the line associated with a shorter wavelength.

We take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.

That is, find the greatest integer value of m for which mλ<d.

since  d / λ = 538×10⁻⁹m / 2.1×10 −6 m ≈ 3

that value is m=3.

There are three complete orders on each side of the m=0 order.

The second and third orders overlap.
