Write a short narrative from the perspective of a mineral moving through the rock cycle. The mineral must undergo at least four
Art [367]

Answer: Mineral and non- mineral components circulate in the environment in different forms whether it is in the form of solid, liquid, or gas.

Explanation:

Plants take up the minerals like calcium, potassium, nitrogen, sulphur, and others from the soil and utilize them for their survival and growth. These minerals are stored in the flowers, leaves, roots, and other plant parts and these plant parts are consumed by humans and animals. So, inorganic minerals from the soil are converted into organic forms by the plants again the minerals are decomposed into inorganic forms after the death of organisms and again mineral is converted into inorganic form in the soil and these minerals can become the component of the rocks after the sedimentation of the soil.

The smallness of the critical angle θc for diamond means that light is easily "trapped" within a diamond and eventually emerges
hoa [83]

Answer:

26.6°

Explanation:

refractive index of diamond, n = 2.23

When a ray of light passes from denser medium to the rarer medium and refracts at an angle of 90 degree from the normal of the surface, such angle of incidence in the denser medium is called the critical angle.

By the Snell's law

\frac{Sini}{Sin r }= n

For critical angle, angle of incidence is critical angle, i = θc and angle of refraction, r = 90

So,

Sin θc / Sin 90 = 1 / 2.23

Sin θc = 0.448

θc = 26.6°

Thus, the critical angle is 26.6°.

An object object travels 24 meters in the +x direction for 3.5 seconds, and then immediately travels some distance in the -x dir
kicyunya [14]

Answer:

The distance in -x axis is 39.77 m

Explanation:

Given that,

Distance in +x axis = 24 m

Time = 3.5 sec

Total time = 9.3 sec

Average velocity = 0

We need to calculate the velocity in +x axis

v=\dfrac{d}{t}

Put the value into the formula

v=\dfrac{24}{3.5}

We need to calculate the velocity in -x axis

v=\dfrac{x}{9.3-3.5}

We need to calculate the distance

Using formula of average velocity

\dfrac{\dfrac{24}{3.5}-\dfrac{x}{9.3-3.5}}{2}=0

x=\dfrac{24}{3.5}\times5.8

x=39.77\ m

Hence, The distance in -x axis is 39.77 m.
