Explanation:

Properties seen in network covalent compound are : high melting and boiling points, hardness, insolubility in polar solvents, electrical insulators.

A network covalent compound is a type of covalent compound where the atoms are bonded together by a continuous network of covalent bonds, forming a giant molecule or a macromolecule.

Some of the properties you would expect to observe with a network covalent compound are:

High melting and boiling points: Network covalent compounds have strong covalent bonds throughout the structure, so a large amount of energy is required to break these bonds, resulting in high melting and boiling points.

Hardness: The strong covalent bonds between atoms in network covalent compounds make them rigid and hard, which is why many of these compounds, such as diamond and silicon carbide, are used as abrasives.

Insolubility in polar solvents: Network covalent compounds are typically insoluble in polar solvents like water because the polar molecules cannot break the strong covalent bonds between the atoms in the network.

Electrical insulators: Most network covalent compounds are electrical insulators because they have no free electrons or ions to carry an electric current.

Brittle: Due to the strong covalent bonds, network covalent compounds are typically brittle, meaning that they fracture easily when subjected to stress.

Estimating the number of apples that is the energy equivalent of 1 gallon of gasoline is difficult, as the energy content of both substances is different. However, we can calculate the energy content of one gallon of gasoline and compare it to the energy content of one apple. So, approximately 1,045,454 medium-sized apples will be the energy equivalent of one gallon of gasoline.

Explanation:

What is the energy content of 1 gallon of gasoline?

The energy content of gasoline is measured in British Thermal Units (BTUs). According to the US Energy Information Administration, one gallon of gasoline contains approximately 115,000 BTUs.Therefore, to calculate the number of apples that are the energy equivalent of one gallon of gasoline, we need to determine the energy content of one apple.

Calculating the energy content of apples:

The energy content of an apple varies depending on its size and type, but on average, one medium-sized apple contains about 95 calories or 0.00011 BTUs.To calculate how many apples are equivalent to one gallon of gasoline, divide the BTU content of gasoline by the BTU content of one apple:115,000 BTUs ÷ 0.00011 BTUs/apple ≈ 1,045,454 applesTherefore, approximately 1,045,454 medium-sized apples are the energy equivalent of one gallon of gasoline.

Answer:

D.yes,low weight does not...

Answer:

Yes, low weight does not mean that their hearts and lungs are healthy.

Explanation:

Many people use low body weight to excuse unhealthy eating and physical inactivity. But body weight is not the best indicator of internal well-being. A much better indicator is your diet. When it comes to your health, it's what's on the inside that counts and you really are what you eat.

There are approximately 5.35 × \(10^{46}\) molecules of water in the world's oceans.

To determine the number of water molecules in the world's oceans, we can use the concept of moles and Avogadro's number.

1 mole of any substance contains 6.022 × \(10^{23}\) particles, which is known as Avogadro's number (NA).

Given:

Total mass of the world's oceans = 1.6 × \(10^{21}\) kg

We need to convert the mass of water into moles by dividing it by the molar mass of water. The molar mass of water (H2O) is approximately 18.015 g/mol.

First, let's convert the mass of the oceans into grams:

Mass of the world's oceans = 1.6 × \(10^{21}\) kg × 1000 g/kg

= 1.6 × \(10^{24}\) g

Now, we can calculate the number of moles:

Number of moles = (Mass of the oceans) / (Molar mass of water)

= (1.6 × \(10^{24}\) g) / (18.015 g/mol)

≈ 8.88 × \(10^{22}\) mol

Finally, to find the number of water molecules, we multiply the number of moles by Avogadro's number:

Number of water molecules = (Number of moles) × Avogadro's number

= (8.88 × \(10^{22}\) mol) × (6.022 × \(10^{23}\) molecules/mol)

≈ 5.35 × \(10^{46}\) molecules

Therefore, there are approximately 5.35 × \(10^{46}\) molecules of water in the world's oceans.

\(a = 7.69\: {m(s)}^{ - 2} \)

Explanation:

\(f = ma \\ a = \frac{f}{m} = \frac{500}{65} = \frac{100}{13} \\ a = 7.6923076923 \: {m(s)}^{ - 2} \)

The first equivalence point, the pH is 0.154, and at the second equivalence point, the pH is also 0.154.

The pb values for the dibasic base b indicate the pH at two different points in the titration process. pb1=2.10 corresponds to the first equivalence point, while pb2=7.65 corresponds to the second equivalence point. To calculate the pH at each of these points, we need to understand the titration process.

In this case, we are titrating a 0.70 M(aq) solution of base b with 0.70 M HCl(aq). The base b is dibasic, which means it can accept two protons (H+) per molecule. The HCl is a strong acid, so it will dissociate completely in water, releasing H+ ions.

At the first equivalence point, the number of moles of base b is equal to the number of moles of H+ ions. This means that half of the base has been neutralized. To calculate the pH at this point, we can use the equation pH = -log[H+]. Since the concentration of H+ ions is 0.70 M, the pH at the first equivalence point is -log(0.70) = 0.154.

At the second equivalence point, all of the base has been neutralized. This means that the concentration of H+ ions is determined solely by the HCl solution. Again, we can use the equation pH = -log[H+]. Since the concentration of H+ ions is still 0.70 M, the pH at the second equivalence point is -log(0.70) = 0.154.

In summary, at the first equivalence point, the pH is 0.154, and at the second equivalence point, the pH is also 0.154.

The total distance traveled by the car when accelerating at a rate of 3 m/s² is 74.67 meters.

Acceleration is the rate at which an object's velocity with respect to time changes. Acceleration is a vector quantity. The direction of the net force acting on an object determines the direction of its acceleration.

The car accelerates from 6 m/s to 22 m/s.

Therefore,

The initial velocity of the car, u = 6 m/s

The final velocity of the car, v = 22 m/s

The acceleration of the car, a = 3 m/s²

By using the equation of motion,

v² - u² = 2as

s = ( v² - u² ) / 2a

s = ( 22² - 6² ) / 6

s = ( 484 - 36 ) / 6

s = 448 / 6

s = 74.67 meters

The object distance at which the magnification will be +0.80 for a diverging lens with a focal length of magnitude 13 cm is:

do = -21.67 cm

To solve this problem, we can use the formula for magnification:

m = -di/do

Where m is the magnification, di is the image distance, and do is the object distance.

We are given that the focal length of the lens, f, is 13 cm. For a diverging lens, the focal length is negative, so we can write:

f = -13 cm

We are also given that the magnification, m, is +0.80. Substituting these values into the formula above, we get:

0.80 = -di/do

Solving for di, we get:

di = -0.80do

Now we can use the lens equation to relate do and di:

1/do + 1/di = 1/f

Substituting the values we know, we get:

1/do + 1/(-0.80do) = 1/(-13 cm)

Simplifying and solving for do, we get:

do = -21.67 cm

However, we need to express our answer with the appropriate units, which are centimeters. Therefore, the object distance at which the magnification will be +0.80 for a diverging lens with a focal length of magnitude 13 cm is:

do = -21.67 cm

(Note that the negative sign indicates that the object is on the opposite side of the lens from the observer, which is consistent with the fact that we are dealing with a diverging lens)

In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

The fact that the speed of light is constant as it travels through a vacuum means that the relationship between the wavelength and frequency of photons is essential to understanding the electromagnetic spectrum. The correct options are a and b.

This constant speed of light is represented by the equation c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency.

Option a is correct. Since the speed of light is constant, if the wavelength of a photon is longer, its frequency must be lower to maintain the constant speed. This inverse relationship means that photons with longer wavelengths indeed have lower frequencies.

Option b is also correct. Radio wave photons have longer wavelengths and lower frequencies than gamma ray photons. This is because gamma rays are at the higher energy end of the electromagnetic spectrum, while radio waves are at the lower energy end.

Option c is incorrect. X-rays have difficulty penetrating the Earth's atmosphere due to their high energy and short wavelengths. This means they cannot be transmitted through the atmosphere around the world as easily as radio waves or other lower energy waves.

Option d is incorrect. Ultraviolet photons actually have more energy than visible photons. They have shorter wavelengths and higher frequencies, which results in higher energy levels according to the equation E = hν, where E is energy and h is Planck's constant.

To calculate the work done by John when lifting a 20kg mass to a height of 2m, we can use the formula: work = force x distance x cos(theta) where force is the weight of the mass (20kg x 9.81 m/s^2 = 196.2 N), distance is the height the mass is lifted (2m), and cos(theta) is the angle between the force and the displacement (cos(0) = 1, since the force and displacement are in the same direction). Substituting these values into the formula, we get: work = 196.2 N x 2m x 1 work = 392.4 J Therefore, John did 392.4 joules of work when lifting the 20kg mass to a height of 2m.

The mass of a planet affects the motion of the planet around the sun through the force of gravity.

According to Newton's law of universal gravitation, every object in the universe attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

The greater the mass of a planet, the stronger its gravitational pull and the more it affects the motion of other celestial objects in its vicinity, including its own orbit around the sun.

In summary, the mass of a planet is a crucial factor that determines its motion around the sun, as it affects the strength of the gravitational forces acting on the planet and its orbit.

Explanation:

Answer:

Because the ball is dropped, we are going to assume its initial velocity is 0. With that said, acceleration is essentially the change in the velocity versus the change in time, hence the unit m/s^2, which can be thought of as “meters per second per second.” The only force acting on the ball is gravity.

That being said, you can simply divide the change in velocity by the change in time, giving you an answer of 9.8 m/s^2, which is the value of g. Even if they did not give you a time, the answer would still always be the value of g (that is if the question pertains to earth), as acceleration due to gravity is a constant.

To determine the difference in orders of magnitude between the scale of the atomic nucleus (10^-15 m) and the scale of the universe (10^24 m), we need to compare their exponents.

The order of magnitude represents the power of ten in scientific notation. In this case, the scale of the atomic nucleus is 10^-15 m, which can be written as 1 × 10^-15 m, and the scale of the universe is 10^24 m, which can be written as 1 × 10^24 m.

To find the difference in orders of magnitude, we subtract the exponent of the smaller value from the exponent of the larger value:

Exponent of the universe scale (24) - Exponent of the atomic nucleus scale (-15) = 24 - (-15) = 24 + 15 = 39
