Answer:

b. location c. luster d. taste

Explanation:

The following physical and chemical properties for identifying the mineral are Color, Hardness, Luster, Taste, Odor, Etc. The properties help in identifying the place of origin the mineral has come from.

In turn, location can be also used to identify a particular mineral or chemical origin. A mineral located in groundwater reserves has deposits of calcium and hence formed through the limestone rocks of the CaCo3 element.

Luster the reflectance properties of the rocks as some minerals don't have lust is called as "earthy," or "dull." And the color is an important property of the mineral and hence is a major tool in identifying the chemical and physical properties.

Other properties being Magnetism, Opaqueness and Specific Gravity.

The ways to identify a mineral are LUSTER, density, hardness, and cleavage.

Answer:

Strait.

Explanation:

After a fast online search, I've found that the list of words are:

Athens

Age of Pericles

satraps

tyrant

Cyrus the Great

hoplites

Parthenon

peninsula

upper-class Athenian women

strait

Well, the definition is:

"A narrow body of water with land on both sides"

This is something like a river, so we need to find which one of these words means something like river.

To do it, let's look at short definitions of each word:

Athens: This is the capital city of Grece. (Isn't the correct option)

Age of Pericles: This refers to a historical period (isn't the correct option)

Satraps: Were governors in the Persian empire (Isn't the correct option)

Tyrant: Refers to a cruel leader (Isn't the correct option)

Cyrus the Great: Was the founder of the Achaemenid Empire (isn't the correct option)

Hoplites: A citizen-soldier (isn't the correct option)

Parthenon: A construction in Grece (isn't the correct option)

Peninsula: A small body of land surrounded mostly by water, but connected to land (isn't the correct option)

upper-class Athenian women: It is self-explained, this isn't the correct option.

Strait: This refers to a narrow passage of water that connects two larger areas of water (like two seas, for example)

Then this one is the correct option.

Gekata [30.6K]

Answer:

1. a = -10 m/s²

2. a = 1.8 × 10³ km/h²; s = 0.31 km

Explanation:

Given:

Initial speed (u): 30 m/s

Final speed (v): 0 m/s (rest)

Time elapsed (t): 3.0 s

Asked:

Acceleration (a)

Solution:

We will use the following expression.

a = (v-u)/t = (0 m/s - 30 m/s)/3.0 s = -10 m/s²

Final Answer:

a = -10 m/s²

Given:

Initial speed (u): 50 km/h

Final speed (v): 60 km/h

Time elapsed (t): 20 s

Asked:

(a) Acceleration (a)

(b) Distance traveled (s)

Solution:

(a) First, we will convert the time to hours.

20 s × 1 h/3600 s = 0.0056 h

Then, we will use the following expression.

a = (v-u)/t = (60 km/h - 50 km/h)/0.0056 h = 1.8 × 10³ km/h²

(b) We will use the following expression.

s = u × t + 1/2 × a × t²

s = 50 km/h × 0.0056 h + 1/2 × 1.8 × 10³ km/h² × (0.0056 h)² = 0.31 km

Final Answer:

a = 1.8 × 10³ km/h²

s = 0.31 km
