All rivers naturally change their path over time, but this one forms meanders

Explanation:

When you stand next to a river, its path doesn't seem to move.

All rivers naturally change their path over time, but this one forms meanders  at an especially fast rate, due to the speed of the water, the amount of sediment in it, and the surrounding landscape.

Answer:

The Weight

Explanation:

Even know it has the same volume does not mean it has the same mass and weighs the same with the items inside the box. Most likely, that the Items inside the box are heavier then the first box Max moved.

Max is helping his parents move to a new house. He picks up one box and is able to carry it into the house. He tries to pick up a second box with an identical volume, but he is unable to lift it. The difference between the two boxes is weight.

Similar items have the identical volume. In other words, two items have the same volume if all of their measures completely match. An object's volume remains unchanged when it is rotated or reflected.

According to Avogadro's law, all gases with an identical volume and the same temperature and pressure have an equal number of molecules. If the temperature and pressure are constant, the volume and amount (in moles) of an ideal gas for a given mass are directly proportional.

The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).

Thus,  He tries to pick up a second box with an identical volume, but he is unable to lift it.  The difference between the two boxes is weight.

The most common way humans contribute to the extinction of organisms is by destroying their habitats. By destroying the natural habitats of organism we are leading them to point where they cant survive.

Extinction of an organism is the gradual disappearance of the entire species of that organism due to natural calamities, human activities or, spreading diseases.

Human activities are the main culprits of the devastation of organisms and their habitats. Humans destroy the natural habitats of plants and animals for their selfish purposes.

Animals then starve and they are not fit to survive in other places which are entirely different from their natural habitat. Therefore, if these activities continues they will extinct.

Work done = force*distance = mass*acceleration*distance

acceleration = 10/3 = 3.33 m/s^2

distance = ((0+10)/2)*3 = 15m

work done = 1500*3.33*15 = 74900 J

Power = workdone/time = 74900/3 = 25000 W

a. The work done on the car in this time interval is 75000 J.

b. And, the power delivered by the engine in this time interval is 25,000 watt.

Given that,

Based on the above information, the calculation is as follows:

(a)

We know that

[tex]w = \frac{1}{2} \times m (v^2 - u^2)[/tex]

Here

Mass = [tex]1.50 \times 103 kg[/tex]

v= 10 m / s

u= 0 m / s

Now place it to the above formula

So, Work done is  = 75000 J

(b)

[tex]Power P = W \div t\\\\= 75000 \div 3[/tex]

= 25000 Watt

Therefore the above are the answers.

The element that glows in signs is xenon.

Explanation:

Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth's atmosphere in trace amounts. Xenon is used in flash lamps, arc lamps, and as a general anesthetic. Xenon emits a blue or lavenderish glow when excited by electrical discharge, it emits a band of emission lines that span the visual spectrum, but the most intense lines occur in the region of blue light, producing the coloration.

ground-dwelling rodents will have to find new shelter

After a catastrophic flood in a grassland ecosystem , ground-dwelling rodents will have to find new shelter.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Pepper has the same state of matter after it is mixed with water.

State of matter of any substance tells about the physical appearance or the space occupied by the atoms of that substance.

From the given option; carbon dioxide, salt and sugar are soluble in water and changes their state of matter to liquid. But pepper is hydrophobic in nature that means it is not soluble in water, so present in the original state after mixing with water.

Hence, option (c) is correct i.e. pepper has the same state.
