Answer:

The maximum potential difference or current can be increased by:

1. increasing the rate of rotation.

2. increasing the strength of the magnetic field.

3. increasing the number of turns on the coil.

Answer:

It depends. Remember that power is voltage x current. So, do you have enough voltage? You can buy modules that increase and decrease voltage. That is one possibility. Please check all safety guidelines of the generator before doing this. modifying the voltage to a generator without making sure it can take more voltage can be counterproductive

Answer:

The length of the flagpole is approximately 87.43 m

Explanation:

The given parameters of the cable attached to the flagpole are;

The point along the flagpole at which the cable is attached = 32.0 m

The angle with respect to the ground at which the raising of the flagpole is halted = 60.0°

The downward force exerted by the cable, [tex]F_v[/tex] = 1.233 × 10⁴ N

The force exerted by the cable to the left = 1.233 × 10⁴ N

Let 'W' represent the weight of the flagpole, at equilibrium, we have;

The sum of vertical forces = 0

Therefore;

[tex]F_v[/tex] + W - R = 0

W - R = -1.233 × 10⁴ N

Taking moment about the support at the base of the pole, we get;

1.233 × 10⁴ × d × cos(60.0°) - 1.233 × 10⁴ ×d× sin(60.0°) + W × d/2 ×cos(60.0°) = 0

∴ W × d/2 ×cos(60.0°) ≈  4513.093·d  

W = 2 × 4513.093/(cos(60.0°)) ≈ 18,052.373 N

R = 18,052.373 + 1.233 × 10⁴ ≈ 30,382.373

R ≈ 30,382.373 N

Taking moment about the point of attachment of the cable to the ground, we have;

W × ((d/2) × cos(60.0°) + 32) = R × 32

∴ (d/2) = ((30,382.373 × 32/18,052.373) - 32)/(cos(60.0°)) ≈ 43.71281

d = 2 × 43.71281 ≈ 87.43

The length of the flagpole, d ≈ 87.43 m

Explanation:

I took the test.

Answer:

A

Explanation:

The image that shows an alignment of earth, moon and sun during spring tide is option A. All of them will be in a straight line.

A spring tide is a type of tide that occurs when the Earth, sun, and moon are aligned in a straight line. During a spring tide, the gravitational pull of the sun and the moon combine, resulting in higher-than-normal high tides and lower-than-normal low tides.

During a spring tide, the position of the sun, moon, and earth is aligned in a straight line. The gravitational force of the moon and sun both act upon the oceans of the Earth, creating a combined effect that results in unusually high tides.

During a spring tide, the moon is either new or full, which means it is in a position that aligns with the sun and Earth. The gravitational pull of the moon and sun reinforce each other, creating a stronger gravitational force on the Earth's oceans.

This causes the water level to rise higher than normal during high tide and lower than normal during low tide. Here, image A shows the correct alignment.

Answer:

1788.402 MJ

Explanation:

Work done = Force (N) x distance (m)

First we have to convert distance into metres:

173.8 x 1000 = 173,800 m

Then plug these values into the equation above:

173,800 x 10290 = 1788402000 J

The reason it's Joules (the unit for energy) is because work done = energy transferred

Now we have to convert Joules into Mega Joules:

1 J = 1/1000000 MJ

1788402000 J = 1788402000/ 1000000 = 1788.402 MJ

Answer:

The answer is below

Explanation:

Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.

Total distance traveled = distance traveled north + distance traveled east + distance traveled south

Total distance traveled = 100 + 50 + 60 = 210 meters

Displacement is the shortest distance between the starting and end points.

displacement² = 50² + (100 - 60)²

displacement² = 2500 + 1600

displacement = 64 meters

The displacement of the journey is vector, because displacement is a vector quantity.

Two waves have the same amplitude but they can have different frequencies. The wave with a higher frequency will have greater energy. Therefore, the given statement is correct.

The frequency of electromagnetic waves or any wave can be described as the number of oscillations in one second. The frequency can be represented as per second or hertz.

The wavelength of the wave can be defined as the distance between two crests or troughs on a wave that is separated by a distance known as wavelength. The wavelength of the waves is expressed in meters.

The relationship between frequency (ν) and energy of the wave:

E = hν

The frequency of the waves has a direct relation with the energy of the waves. Therefore, the wave which has a higher frequency will carry greater energy whether they have the same amplitude.

Answer: The balloons repel each other but attract the rabbit fur.

Brainliest pwease if I could do you any help!

Here, both the balloons gains a negative charge through rubbing and they attracts to the neutral rabbit fur. But the balloons themselves repel each other. Hence, option B is correct.

When a  material rub on a surface its electrons gets aligned and acquire a negative charge. This negative charge when comes in contact with a neutral material, the second one get partially polarized and gets attracted to the negative charge.

This flow of electrons through induced polarization is called static electricity. When the balloon are rubbed with the neutral rabbit fur and gets negatively charged by friction.

This negatively charged balloons repel each other but they induce a polarity to the neutral rabbit fur and its positive charges gets aligned with the negative charges results in electrostatic attraction.

Answer:

a) time taken = 1.427 s

b) final speed before hitting the ground = 14 m/s

Explanation:

height of cliff = 10 m

acceleration due to gravity = 9.81 [tex]m/s^{2}[/tex]

time taken for stone to reach bottom of cliff = ?

velocity of stone just before hitting the ground = ?

To find the time taken, we will use Newton's equation of motion

using

[tex]v^{2} = u^{2} + 2as[/tex]

where

v = final speed of stone before hitting the ground

u = initial speed of the stone (u = 0 since the stone started falling from rest)

a = acceleration due to gravity = 9.81 [tex]m/s^{2}[/tex]

s = height of the cliff = 10 m

Solving, we have

[tex]v^{2} = 0^{2} + 2(9.81 * 10)[/tex]

[tex]v^{2} = 2*98.1[/tex]

[tex]v^{2} = 196.2[/tex]

[tex]v=\sqrt{196.2} = 14 m/s[/tex]

From the first equation of motion,

[tex]v = u + at[/tex]

where t = time taken for stone to reach bottom of cliff

imputing values, we have

[tex]14 = 0 + (9.81 * t)[/tex]

[tex]t = \frac{14}{9.81} = 1.427 s[/tex]

It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

Answer:

B) –1.1 × 1011 N

Explanation:

Since the second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs, the electrical force between q₂ and q₃ is -1.1 × 10¹¹ N

To answer the question, we need to find the electrical force of attraction between two charges and this is given by Coulomb's law

This states that the electrical force of attraction between two charges, F is directly proportional to the product of the charges q and Q and inversely proportional to the square of their distance apart, d.

So, mathematically F = kqQ/d²

Now, given that there are three charges are on a line. A positive charge is on the far left labeled q₁ = + 6 Coulombs. The second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs.

So, the electrical force of attraction between q₂ and q₃ is F = kq₂q₃/d² where

Substituting the values of the variables into the equation, we have

F = kq₂q₃/d²

F = 8.99 × 10⁹ Nm²/C² × (-4 C) × (+ 3 C)/(1 m)²

F = 8.99 × 10⁹ Nm²/C² × (-12 C²)/(1 m)²

F = -107.88 × 10⁹ Nm²/1 m²

F = -1.0788 × 10¹¹ N

F ≅ -1.1 × 10¹¹ N

Since the second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs, the electrical force between q₂ and q₃ is -1.1 × 10¹¹ N

Weather such as raining has water molecules/droplets thats been evaporated from the ocean and other areas that's wet, the water will connect and soon the mass of the water will become heavy causing rainfall. Snow in another case has been caused to freeze from low climates creating a snow flake to fall from the sky. Hail is another case however the water that becomes ice is far more larger.

The variety of activities that take place daily in our atmosphere makes up for the weather.

The weather varies across the globe and changes over a few minutes, hours, days, and weeks. The troposphere, the region of Earth's atmosphere closest to the surface, is where most weather occurs.

Changes in air pressure determine the weather that occurs in a given place. The weight of the enormous quantities of air molecules that make up the atmosphere is what causes air pressure.

Usually, clear, blue skies are seen when air pressure is high. The high pressure prevents clouds from developing by causing air to flow down and fan out as it gets close to the ground.

Low air pressure causes air to move together before converging upward, where it rises, cools, and forms clouds.

Answer:

La rapidez media es 25 m/s en ambos casos.

Explanation:

Podemos definir como rapidez media al cociente entre la distancia total recorrida y el tiempo que se tardó en recorrer dicha distancia.

Así tenemos:

Rapidez media = Distancia/tiempo.

Entonces si el guepardo recorre 100m en 4 segundos, su rapidez media es:

Rapidez media = 100m/4s = 25 m/s

En el caso de que el guepardo recorre 50 metros en 2 segundos, su rapidez media será:

rapidez media = 50m/2s = 25m/s

Es el mismo resultado, pues recorrió la mitad de distancia en la mitad de tiempo.
