how can you reduce output voltage to 6v in transformers if the input voltage is 240v​

Answers

Answer:

[tex]N_P = 40\ N_S[/tex]

To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.

Explanation:

The change in voltage of a transformer depends upon the turns ratio of the transformer between secondary and primary coil. Following formula can be used to determine the turns ratio in this case:

[tex]\frac{N_P}{N_S} = \frac{V_P}{V_S} \\\\[/tex]

where,

[tex]N_P[/tex] = No. of turns in the primary coil

[tex]N_S[/tex] = No. of turns in the secondary coil

[tex]V_P[/tex] = voltage in the primary coil = 240 V

[tex]V_S[/tex] = voltage in the secondary coil = 6 V

Therefore,

[tex]\frac{N_P}{N_S} = \frac{240\ V}{6\ V} \\\\N_P = 40\ N_S[/tex]

To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.

A system engine generating 5 hp is raising a load weighting 2000 lb. How high will the load be raised in 10s?

Answers

Answer:

h = 44.5 m

Explanation:

Given that,

Power of the engine, P = 5 hP = 3728.5 W

Weight of the load, W = 2000 lb = 8900  kg

We need to find how high the load be raised in 10 s.

We know that,

Power, [tex]P=\dfrac{W}{t}[/tex]

Where

W is work done

Also,

1 Pound = 4.45 newtons earth (N)

[tex]P=\dfrac{F\times h}{t}\\\\h=\dfrac{Pt}{F}\\\\h=\dfrac{8900\times 10}{2000}\\\\h=44.5\ m[/tex]

So, the height raised by the load is 44.5 m.

The trapdoor swings open and the ball falls to the ground. The ball does not bounce when it hits the ground. Show that the final speed of the ball at the instant before it hits the ground is about 5 m/s.

Answers

Answer:

5 m/s

Explanation:

As the ball falls to the ground, it is acted upon by a force which is due to the gravitational force. Hence, the ball falls with an acceleration called the acceleration due to gravity.

Let us assume that the acceleration due to gravity (g) = 10 m/s², Since initially, the body was at rest, hence the initial velocity (u) = 0 m/s. The height to the ground (h) = 1.3 m. Hence using the equation of motion, the final velocity (v) is:

v² = u² + 2gh

Substituting:

v² = 0² + 2(10)(1.3)

v² = 26

v = √26 = 5

v = 5 m/s

The smell of hot sizzling food reaches you several metres away but to get the smell from cold food you have to go close.​

Answers

Answer: The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close because the kinetic energy of the particles of matter increases with the increase in temperature. In cold foods, kinetic energy is less while in hot foods, kinetic energy is more

hope this helps

Smell spreads due to diffusion. In hot food the molecules have a lot of kinetic energy , and they therefore spread fast , whereas in cold food the kinetic energy of the molecules are less and they don't spread far.

A 8.6*10^ -6 C charge is places 1.00 m away from a 2.3 * 10 ^ - 4 * C charge. How large is the force of repulsion between the two charges?

Answers

Answer:

The force of repulsion is 17.802 N

Explanation:

Given;

magnitude of the first charge, q₁ = 8.6 x 10⁻⁶ C

magnitude of the second charge, q₂ = 2.3 x 10⁻⁴ C

distance between the two charges, r = 1 m

The force of repulsion is calculated using Coulomb's law;

[tex]F = \frac{Kq_1q_2}{r^2} \\\\F = \frac{9\times 10^9 \times 8.6\times 10^{-6} \times 2.3\times 10^{-4}}{1^2} \\\\F = 17.802 \ N[/tex]

Therefore, the force of repulsion is 17.802 N

Magnitude of force F experienced by a certain object moving with speed v is given by F=Kv race to 2, where K is constant. Find the dimension of K

Answers

Answer:

MT⁻¹

Explanation:

Given equation:

F = Kv        --------------(i)

Where;

F = Magnitude of force experienced by the object

v = speed at which the object is moving

K = constant.

To get the dimension of K, follow the following steps:

i. Make K subject of the formula in equation(i)

K = F / v

ii. Get the dimension of force F and speed v

Dimension of force = MLT⁻²

Dimension of velocity = LT⁻¹

iii. Substitute these dimensions into the result of (i) above;

K = MLT⁻² / LT⁻¹

iv. Simplify the result in (iii)

First, the Ls in the numerator and denominator will cancel out

K = MT⁻² / T⁻¹

Next, the Ts will be expressed as follows

K = MT⁻² x T¹           [using the law of indices]

K = MT⁻²⁺¹

K = MT⁻¹

Therefore, the dimension of K is MT⁻¹

Which of these historical events led to a major imbalance in the carbon cycle?
A. American Revolution
B. American Civil War
C. The Industrial Revolution
D. The Renaissance

Answers

Answer:

C

Explanation:

I think it's industrial revolution because many industries were developed which emitted a lot of carbon gases in the atmosphere.

The Industrial Revolution events led to a major imbalance in the carbon cycle. The correct option is C.

What is Industrial Revolution?

The Industrial Revolution, which began in the late 18th century and continued through the 19th century, led to a major increase in the burning of fossil fuels such as coal, oil, and gas. This led to a significant increase in carbon emissions and a disruption of the natural carbon cycle.

Prior to the Industrial Revolution, the carbon cycle was relatively balanced, with carbon being naturally cycled through the atmosphere, oceans, plants, and animals. However, the burning of fossil fuels has released large amounts of carbon dioxide(CO₂) into the atmosphere, which has led to an increase in atmospheric carbon dioxide(CO₂) levels and contributed to global warming and climate change.

Other historical events such as the American Revolution, American Civil War, and the Renaissance did not have a significant impact on the carbon cycle in the same way that the Industrial Revolution did.

Therefore, The correct answer is C i.eThe Industrial Revolution.

What is work?

The notion of work in science is significantly different from what it is understood to entail in ordinary life. Every time work is performed, energy is transmitted, as shown by the definition of work in physics.

A force must be applied and there must be movement in the force's direction for a work to be completed scientifically. Having said that, we may state that The product of the component of the force acting in the displacement's direction and its magnitude is work.

Mathematically work done can be expressed as:

work done = force × displacement × cosθ

Where θ is the angle between the force and the displacement .

Here, the  car remains stuck, that means, no displacement happens. So. Lucas do a work of 0 joule.

A ball is thrown straight up with a speed of 30 m/s, and air resistance is negligible. How long does it take the ball to reach the maximum height?

Answers

Answer:

3 seconds

Explanation:

Applying,

Applying,

v = u±gt................ Equation 1

Where v = final velocity, u = initial velocity, t = time, g = acceleration due to gravity.

From the question,

Given: v = 0 m/s ( at the maximum height), u = 30 m/s

Constant: g = -10 m/s

Substitute these values into equation 1

0 = 30-10t

10t = 30

t = 30/10

t = 3 seconds

Discuss how our lives on Earth are directly related to our relationship and positioning with the Sun in our Solar System.

Answers

Answer:

They are because 1. New years culture benefits 2. Gives the right amount of heat as well as a day/ night cycle and the 4 seasons because of the earths tilt

Answer:

Explanation:

Our lives on earth are directly connected to the sun and our solar system because they give the right amount of heat and as well as the day and night cycle. Furthermore, due to the earth’s tilt, we get our four seasons which are very important to us as humans, getting different seasons and weather conditions.  

The solar system also affects the tides and  

A Long time ago, the Moon was closer to the Earth and spinning rapidly. The Moon’s tidal bulges didn’t align with the Earth, and the Earth’s gravity tugged on them, slowing the Moon’s spin and moving it farther away. As it moved farther away, the time it took to orbit once around the Earth increased: Its orbital period got longer. Eventually, the lengthening rotation of the Moon matched how long it took to go around the Earth. When that happened, the axis of the bulges pointed right at the Earth. That’s why the Moon only shows one face to us! It spins once per month and goes around us once per month.

Gravity is a force, and it weakens with distance. An important thing to note is that we measure gravity from the center of mass of an object, not its surface. One way to think of the center of mass of an object is the average position in an object of all its mass. For an evenly distributed sphere, that’s its center.

Since gravity weakens with distance, the force of Earth’s gravity on your head is less than it is on your feet, it’s way too small for you to ever notice. This change in the force of gravity over distance is what astronomers call the tidal force. The overall effect of the tidal force is to stretch an object.

The Moon has gravity. Just as the bulge is pulling the Moon ahead, the Moon is pulling the bulge back, slowing it down. Because of friction with the rest of the Earth, this slowing of the bulge is actually slowing the rotation of the Earth itself, making the day longer. The effect is small, but it’s measurable.

The constellations and astronomy give us our zodiac signs, and from previous knowledge, I know that zodiac signs impact our personalities greatly. If constellations were not found then zodiac signs wouldn’t have been created.
