Explanation:

The athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

To find the time the athlete must jog, we'll first convert the distance from kilometers to miles, then use the formula:

Time (in hours) = Distance ÷ Speed

1 kilometer is approximately 0.621371 miles.

So, the distance in miles is:

42.19 km × 0.621371 miles/km ≈ 26.21875 miles

Now, we can find the time in hours:

Time (in hours) = 26.21875 miles ÷ 9.00 mph ≈ 2.9131944 hours

To convert hours to minutes, multiply by 60:

Time (in minutes) ≈ 2.9131944 hours × 60 min/hour ≈ 174.79167 minutes

Now, let's round this to two decimal places and express the result in scientific notation:

Time (in minutes) ≈ 174.79 minutes

To write it in the requested form (using scientific notation), we move the decimal point two places to the right:

Time (in minutes) ≈ 1.7479 × 10 minutes

So, the athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

Answer:water  erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.

Explanation:

Answer:Hope this helps :) if so pleas could you mark brainliest:) enjoy!

Explanation:

The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.

Hot-Water Solutions Groundwater works its way down and is heated by magma, and then reacts with minerals to form a hot liquid solution. H. Dissolved metals and other elements crystallize out of the hot fluid to form new minerals, such as gold, copper, sulfur, pyrite, and galena.

Answer:

What happens to hot water beneath the Earth as it moves up through fractured rock?

Circulating groundwater that comes into contact with the cooling magma is heated and rises to the surface along rock fractures to form either a thermal spring, figmarole, or geyser.

Answer:

Explanation:

Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.

This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.

In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.

Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.

Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.

Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.

Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

Temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

Accuracy is the capacity of an instrument to measure the precise value. In other words, it refers to how closely the measured value resembles a reference or genuine value. Small readings can be taken to increase accuracy. The calculation's inaccuracy is decreased by the little reading.

The precision of a material is defined as the degree to which two or more measurements agree with one another. It is incredibly precise but not always accurate to measure something if you weigh it five times and get 3.2 kg each time. Accuracy is not necessary for precision.

The degree to which a measurement is accurate in relation to its real value. The degree to which the same results are produced by repeated measurements under the same circumstances is known as precision.

Therefore, temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.

Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.

Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.

Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).

Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.

Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.

Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

The very important phase in mitosis called the  metaphase is most useful in the healing process. In this phase the damaged cells are repaired or replaced with the new cells.

All eukaryotic cells undergo mitosis (plants, animals, and fungi). It is the method through which a plant, an animal, or a fungus renews and grows its cells. Our bodies are always undergoing it.  

The ongoing death of cells is known as apoptosis (programmed cell death). These cells need to be regularly replenished in order for you to be alive and properly functional. This process depends on mitosis.

We are able to expand, recover from injuries, and replace damaged cells because of mitosis. Since this is the only method that these cells can replicate, mitosis is also crucial in creatures that reproduce asexually. The most useful phase in  mitosis that is responsible for healing is metaphase.
