Answer:

Latitudes are used to indicate a precise location of any feature on the earth's surface.

Temperature changes with latitudes .At higher latitudes, the Sun's rays are less direct. The farther an area is from the Equator, the lower its temperature. At the poles, the Sun's rays are least direct.Near the equator sun's rays are perpendicular resulting into very high temperatures. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.

Answer:

The mass is 20, 89 grams of He.

Explanation:

We calculate the weight of 1 mol of He, from the atomic weight of each element obtained from the periodic table: Weight 1 mol He= 4, 0020602 g. 1 mol He-----4, 0020602 g. 5,22 mol He---x= (5,22 mol He x4, 0020602 g)/ 1 mol He= 20, 89 g

hope this helps also can i get brainliest

The mass of 5.22 mol of He will be 20.84 grams.

We have 5.22 mol of He.

We have to calculate its Mass.

Helium is a chemical element with the symbol He and atomic number 2. It is a gas which is colorless, odorless, tasteless, non-toxic, inert and monatomic.

According to the question -

Number of moles of Helium = 5.22 mol

Now, I mole of Helium will have its mass equal to its Atomic weight. Therefore -

Mass of 1 mole of He = 4.002602 g

So, the mass of 5.2 mol of He will be = 5.2 x 4.002602 = 20.84 grams

Hence, the mass of 5.22 mol of He will be 20.84 grams.

Answer:

New pressure = 7.51 atm

Explanation:

Given that,

Initial pressure, P₁ = 4.5 atm

Initial temperature, T₁ = 100°C = 100+273 = 373 K

Final temperature, T₂ = 350°C = 350 + 273 = 623 K

We need to find the new pressure. Using the below relation as follows :

[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{4.5\times 623}{373}\\\\P_2=7.51\ atm[/tex]

So, the new pressure is 7.51 atm.

a minimum of three seismograph stations are needed to find an earthquake's epicenter using the S-P time method.

Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. ... Knowing this helps them calculate the distance from the epicenter to each seismograph.

polarity increases as electronegativity increases i guess so that is supposed to be the answer

Explanation:

The two half equations are;

3e + HNO3 → NO

S→ H2SO4 + 6e

When balancing half equations, we have to make sure the number of electrons gained is equal to the number of electrons lost.

Which factor will you use for the top equation?

We multiply by 2 to make the number of electrons =  6e

Which factor will you use for the bottom equation?

We multiply by 1 to make the number of electrons = 6e

whether a trait is learned or inherited

Explanation:

The nature versus nurture debate involves the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) influences. Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.

The debate called Nature vs. nurture is about whether a trait is learned or inherited. This is an investigation on learned traits and nurtured traits in humans. Thus option A is correct.

All living things are learning something during their growth. These learning mold up one's personality and cannot be created by birth. Like the good characteristics we are learning from schools. These behaviors are called learned traits.

Some traits or behaviors are created by birth itself and they are called natural traits. The nature versus. nurture debate is a philosophical, scientific, and cultural discussion about whether human culture, conduct, and personality are largely influenced by nature or nurture.

Environment, culture, and experience are the most prominent definitions of nurture in this discussion, whereas nature is frequently regarded as genetic or hormone-based behaviors, characteristics, and dispositions.

Answer:

17.21°C

Explanation:

Using the following formula;

Q = m × c × ∆T

Where;

Q = amount of heat in joules

m = mass of substance in grams

c = specific heat capacity of water (4.184 J/g°C)

∆T = final temperature - initial temperature

According to the information provided in this question,

Q = 1,785 cal

1 cal = 4.184 J

1785 cal = 7468.4J

m = 343grams

c = 4.18J/g °C

initial temperature = 12°C

Using Q = m × c × ∆T

7468.4 = 343 × 4.18 × (T - 12)

7468.4 = 1433.74(T - 12)

7468.4 = 1433.74T - 17204.88

7468.4 + 17204.88 = 1433.74T

24673.28 = 1433.74T

T = 24673.28 ÷ 1433.74

T = 17.21°C

Answer:

15 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 10 L

Initial pressure (P₁) = 1140 torr

Final pressure (P₂) = 1 atm

Final volume (V₂) =?

Recall:

1 atm = 760 torr

The new (i.e final) volume of the gas can be obtained as follow:

Initial volume (V₁) = 10 L

Initial pressure (P₁) = 1140 torr

Final pressure (P₂) = 760 torr

Final volume (V₂) =?

P₁V₁ = P₂V₂

1140 × 10 = 760 × V₂

11400 = 760 × V₂

Divide both side by 760

V₂ = 11400 / 760

V₂ = 15 L

Therefore, the new volume of the gas is 15 L

Gravitational force is the force between the sun and the Earth keeps the Earth in its orbit. The period of revolution is the time it takes for Earth to complete one orbit.

Gravitational force is a kind of attraction force which acts between the two bodies.

Sun's gravitational force is a 3 dimensional attraction force under which earth is present. And due to centripetal force of sun, orbit of earth is present in the stationary state. Earth revolves around the sun to complete one round of orbit and this motion is known as revolution of earth.

Hence, gravitational force is present between the sun and the earth, and revolution is the time to complete one orbit.

Answer:

molecule at low temperature and high pressure

Explanation:

this is because two of the postulates of kinetic theory of gases hold true only when there is low pressure and high temperature. as the pressure goes on increasing and temperature goes on decreasing, a molecule will deviate from ideal behavior.
