Answer:

The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. Hope this helps!

Weathering is when the weather itself changes something, like when a metal bike gets rusty after sitting outside for a long time, or when a plant grows out of concrete.

Erosion is when something gets eroded away at. Like when something has water or wind is flowing against it so much that it changes shape. This is how canyons are made.

Deposition is when a gas turns into a solid, removing energy and skipping the liquid step (frost forming on car window)

Answer:

o.75

Explanation:

A train moving at a velocity of 15 m/s is accelerated to 24m/s over a 12 second period, time traveled by the train is 12 seconds.

The initial velocity u of the train is 15 m/s, the final velocity v is 24 m/s, and the time t is 12 seconds. The train is undergoing uniform acceleration.

We can use the kinematic equation to relate the initial velocity, final velocity, acceleration, and time:

v = u + at

Solving for t:

\(\[ t = \dfrac{v - u}{a} \]\)

Given that a is the acceleration and is calculated as:

\(\[ a = \dfrac{v - u}{t} \]\)

Substitute the given values:

\(\[ a = \dfrac{24 \, \text{m/s} - 15 \, \text{m/s}}{12 \, \text{s}} \]\)

\(\[ a = \dfrac{9 \, \text{m/s}}{12 \, \text{s}} \\\\= 0.75 \, \text{m/s}^2 \]\)

Now substitute the calculated acceleration back into the equation for \( t \):

\(\[ t = \dfrac{v - u}{a} \\\\= \dfrac{24 \, \text{m/s} - 15 \, \text{m/s}}{0.75 \, \text{m/s}^2} \]\)

\(\[ t = \dfrac{9 \, \text{m/s}}{0.75 \, \text{m/s}^2} \\\\= 12 \, \text{s} \]\)

Thus, the time traveled by the train is 12 seconds.

The Grand Canyon began its formation about 5 my ago by the erosive action of the Colorado River. Its sedimentary layer composition reflects its history, keeping fossilized living forms that used to inhabit the area.

--------------------

The Grand Canyon formation began approximately 5 million years ago, thanks to the erosive action of the Colorado River.

The strength of the colorado river caudal, together with deglaciation and humidity factors, began to cause an uncontrollable erosion process in these lands that were previously part of the sea bottom.

Originally many strata and sediments accumulated at the bottom of the ocean. With time these extensive areas were exposed when the Rocoses Mountains got formed by the end of the cretaceous (70 million years ago).

Now, by looking at the composing layers, it is possible to understand its formation.

The Grand Canyon is almost entirely composed of sedimentary rock.

It was formed while sediments of sand and mud got deposited in thick layers at the bottom of the ocean and got compacted through the pass of time until becoming a rock.  

Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.  

According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.

Each layer keeps fossilized organisms that used to inhabit this area in the past.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Answer: The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

Explanation:

Force is defined as the product of object's mass and acceleration.

Mathematically,

F = ma     ......(1)

or,

a = F/m      .....(2)

where,

F = Force exerted on an object = 60N

m = mass of an object = 30kg

a = acceleration of the object = ?

Putting values in above equation, we get:

a = 60 kg.m/s^2/30 kg = 2m/s^2

The acceleration of the car is 2m/s^2.

From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.

And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.

Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

A net force of 60 N north acts on an object with a mass of 30 kg , so according to Newton's second law of motion the acceleration of the object would be 2 m / s²,the amount of acceleration would decrease if the mass of the object increases.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

F =m × a

As given in the problem, a net force of 60 N north acts on an object with a mass of 30 kg.

60 = 30 × acceleration

acceleration = 60 / 30

                     = 2 m / s²

Thus, the acceleration of the object would be 2 m / s² , and the acceleration would decrease if the mass of the object increases.

Burning fossil fuels such as coal and gasoline

We know that burning fossil fuels, such as coal and gasoline, is a significant human activity that contributes to the formation of acid rain.

When fossil fuels are burned, they release pollutants into the atmosphere, including sulfur dioxide (SO2) and nitrogen oxides (NOx).

These pollutants can react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3), which are major components of acid rain.

Therefore the correct answer is

The statement "A fossil of an organism that lived during only one time is found in only one kind of rock layer or stratum. If two strata contain the same index fossil, a geologist will know they are part of the same layer" this is definitely true.

An index fossil may be defined as a type of fossil which is significantly utilized in order to define and identify geologic periods. Such fossils are dead and organic remains of past organisms that were preserved and buried deep into the soil millions of years ago.

The existence of any specific fossil reveals the time period as well as the layer of rock or stratum.

If by chance two strata contain the same index fossil, it will definitely represent the same time period along with the same stratum and finally, a geologist will know they are part of the same layer.

Therefore, the given statement is definitely true.

Explanation:

Answer:  Mountains block the winds that bring rain clouds.

Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences
