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.

When a cell is beyond repair, lysosomes help it to self-destruct in a process called apoptosis.

Answer: A lysosome is a membrane-bound cell organelle that contains digestive enzymes soooo. They break down excess or worn out cell parts, they may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

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.

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 inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength.

Metal is any of a group of substances with strong thermal and electrical conductivity, malleability, ductility, plus high light reflection.

The inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength, but rather are transitioned from several dissimilar levels to higher tiers, with several different wavelengths having joined to create white.

Therefore, the inference that can be made regarding the electronic transition that a magnesium atom is capable of experiencing is that the photons generated are not of a single wavelength.
