There is a close relationship between magnetic forces and the generation of electric current. Explain how magnets can be used to generate electric current and how electric current can be used to create electromagnets. For each, give an example of a device you would find around the home.

Answers

Answer 1

Inside a generator is a magnet, some electrical wire, and a source of mechanical energy. The mechanical energy moves the wire into the magnetic field of the magnet so that the wire cuts through the magnetic lines of force. As a result, electric current is produced. Electric generators can come in all sizes

Answer 2

Answer:

If a magnet is continuously moved to and fro in a coil or vise versa , due to change in magnetic field passes through a coil , electric current can be produced, it called electromagnetic induction.

And if current flows in a coil , it will behave like a magnet , that is called Electromagnetism.

Explanation:

What is electromagnetic induction and Electromagnetism ?According to the Faraday's law , when magnetic field passing through a coil is changed , an electric potential is developed , that causes current , the phenomenon is called Electromagnetic induction.In it ,the induced emf (potential)is directly proportional to the rate of change of magnetic flux,[tex]e = N. \frac{(B.A)}{dt}[/tex] Example- Generator.According to the Clock wise rule , when current flows in a coil , according to the direction of current , its one face become N pole and S pole, thus it becomes a magnet or tiny magnet .Example- Solenoid.

Hence Electromagnetic induction and electromagnetism can be defined.

How much heat is absorbed by a 66g iron skillet when its temperature rises from 7oC to 20oC?

Answers

The heat absorbed is calculated using the following equation:
Q = mCΔT

Q = heat absorbed
m = mass = 66 g
C = specific heat of iron = 0.449 J/g.°C
ΔT = temperature change = 20 - 7 =13°C

Therefore,
Q = 66*0.449*13 = 385.242 J

problems with solar energy include

Answers

the inability of current technology to capture large amounts of the Sun's energy the inability of current technology to store captured solar energy inconsistencies in the availability of the resource lack of demand for solar energy.

Final answer:

The problems with solar energy include its intermittency and the high upfront cost of battery storage systems. The production of photovoltaic cells generates hazardous waste, and deployment of large-scale solar systems can harm undeveloped habitats. Also, solar energy cannot directly power all sectors like cars and airplanes due to its diffuse nature.

Explanation:

There are a number of challenges and problems associated with the use of solar energy. Some primary issues include its intermittency, as solar energy capture is not constant, and can be particularly low during the nighttime or in seasons with less sunshine. This inconsistency can be offset by battery storage, but such storage solutions add substantial cost, need regular maintenance, and require the environmentally unfriendly process of battery replacement.

Another concern is the environmental impact of photovoltaic (PV) cells, the main technology for generating solar energy. The process of manufacturing PV cells requires the use of chemicals and solvents, generating some hazardous waste. Besides, the deployment of large-scale solar arrays in undeveloped areas or fragile ecosystems like deserts can cause habitat destruction. Solar thermal systems, another form of solar energy, also pose problems as they use potentially hazardous fluids for heat transfer and need significant amounts of water for cleaning and cooling.

Finally, solar energy can't directly power some sectors and applications such as cars and airplanes due to its diffuse nature, making it not entirely substitutable with other energy sources. While the sun provides an abundant source of energy, transitioning to a solar-powered society poses significant challenges.

The earth takes 1 year to revolve around the sun at 1 A.U. distance (an astronomical unit = 93,000,000 miles). If a planet were 4 A.U. from the sun, how many years would it take to make 1 orbit?

Answers

Kepler's third law states that the square of the orbital period is proportional to the cube of the semi-major axis of its orbit. In equation form, P^2 / a^3 = constant. For the earth, (1 y)^2 / (1 AU)^3 = 1, so the constant is 1. For a planet 4 AU from the sun:
P^2 / (4 AU)^3 = 1P^2 = 64P = 8 years

a ball is thrown horizontally from the roof of a building 45m tall and lands 24m from the base what is the initial speed?

Answers

To find the initial speed of a ball thrown horizontally from a 45m tall building, we first calculate the time of flight using the vertical motion equation and then determine the initial horizontal speed using the range and time of flight.

Finding the Initial Speed of a Horizontally Thrown Ball

To calculate the initial speed of a ball thrown horizontally from the roof of a building that is 45 meters tall and lands 24 meters from the base, we can use the kinematic equations of motion for projectile motion.

Step 1 - Time of Flight

To find the time it takes for the ball to hit the ground, we use the vertical motion equation:

s = ut + 0.5*at^2

Since the ball is thrown horizontally, the initial vertical velocity (u) is 0 m/s. s is the height of the building (45 m) and a is the acceleration due to gravity (9.8 m/s2).

By substituting the known values, we can solve for t.

Step 2 - initial Horizontal Speed

Now, knowing the time of flight, we can find the initial horizontal speed(vx) using the horizontal motion equation:

Range = vxt

The range is given as 24 m. Therefore, vx = Range / t.

Final Answer

After calculating, we get the initial horizontal speed of the ball, which is necessary to cover the horizontal distance within the derived time of flight.

What is the electric potential of a 2.2 µC charge at a distance of 6.3 m from the charge? Recall that Coulomb’s constant is k = 8.99 × 109 N • ___ V
What is the electric potential at a distance of 99 m from the charge?___ V

Answers

According to Edge, the answers is

3100 V

and

200v

Final answer:

The electric potential of a 2.2 µC charge at a distance of 6.3 m is 3.14 × 10^6 V. At a distance of 99 m, the electric potential is 2.02 × 10^4 V.

Explanation:

To calculate the electric potential, we can use the equation V = kQ/r, where V is the electric potential, k is Coulomb's constant (8.99 × 10^9 N • V^-2 • m^2 • C^-2), Q is the charge, and r is the distance from the charge.

For a charge of 2.2 µC at a distance of 6.3 m, we can plug in the values to find:

V = (8.99 × 10^9 N • V^-2 • m^2 • C^-2)(2.2 × 10^-6 C)/(6.3 m) = 3.14 × 10^6 V

Similarly, for a distance of 99 m, the calculation would be:

V = (8.99 × 10^9 N • V^-2 • m^2 • C^-2)(2.2 × 10^-6 C)/(99 m) = 2.02 × 10^4 V

The difference in the composition of the terrestrial planets and the gas giants can be explained by the different condensation ____________________ in the regions near and far from the sun during the formation of the solar system.

Terrestrial rocky planets are mostly made of metals, which need higher temperatures than gases in order to condense.
According to the Solar Nebula theory, temperatures high enough to condense metals were closer to the Sun, while towards the outside of the System, temperatures where lower.
This is the reason why terrestrial rocky planets are closer to the Sun, while gaseous planets are further from the Sun.

Hence, the difference in the composition of the terrestrial planets and the gas giants can be explained by the different condensation temperature in the regions near and far from the Sun during the formation of the Solar System.

Franklin’s hometown is flooding due to a severe storm. He is evacuating the area in his vehicle. What should he do if he comes across a flooded area or flowing water?

Answers

Franklin must not drive through a flood for there may no road at all under the water, unless he is familiar with the road and the flowing water is below one foot.

Moreover, if negotiating a flooded section of road, he must drive in the middle where the water will be at its shallowest and he must not drive through water against approaching vehicle to consider other drivers.

Franklin should not attempt to cross any areas with flowing water because he could get injured or swept away. Franklin should also not drive on flooded roadways because it can be hard to tell how deep the water is and his vehicle could easily get stuck. If his car does get stuck, Franklin should leave it immediately.

what is the mass of a 4900 N bobsled

Answers

A single kilogram is equivalent to 9.8 newtons, meaning that to find the weight of the bobsled, you would simply divide the weight by 9.8. Doing this we find that the bobsled is 500kg

4900 / 9.8 = 500

Answer:

500 Kg.

Explanation:

The problem is giving us the weight of the object the weight is different from the mass of an object

Weight is the mass of any object multiplied by gravity (the value of gravity is approximately [tex]9.8\frac{m}{s^2}[/tex] ).

The unit of weight are newtons that equals

[tex]N= Kg.\frac{m}{s^2}[/tex]

[tex]W= m.g[/tex]

we cleared the mass of the formula

[tex]W=m.g\\ m=\frac{W}{g} \\ m= \frac{4900N}{9.8 \frac{m}{s^2} }= 500 Kg[/tex]

A remote control car travels at a uniform speed of 3.5 m and reaches its destination in five minutes. How far did the remote control car travel

Answers

The speed of the remote control carriage is uniform = 3.5m / s.
The elapsed time is 5 minutes.
You can use the formula
speed = distance / time.
Clearing the distance, which is what we want to find, we have:
distance = speed*time.
However, the speed is in units of seconds and the time in units of minutes. To perform the operation we need to have everything in the same units.
So.
5minutes x 60seconds / 1minute = 300 seconds
Finally:
distance = 3.5m / s * 300s = 1050 meters.
The remote control car traveled 1050 meters

If light intensity obeyed an inverse square law you would expect to find the intensity of light to decrease as the square of the distance increases?
True or false

Answers

Inverse square law: [tex] \frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2 [/tex]
where
[tex]I_{1}[/tex] is the intensity at distance 1
[tex]I_{2}[/tex] is the intensity at distance 2
[tex]d_{1}[/tex] is distance 1
[tex]d_{2}[/tex] is distance 2

The inverse squared law state that intensity decreases in inverse proportion to the distance squared. So if light obeyed that rule, it will decreases its intensity as the square of the distance increases.

We can conclude that the correct answer is: true.

What are non examples of Asexual reproduction

Answers

Bacteria and Binary Fission-
Many single-celled organisms rely on binary fission to reproduce themselves. All bacteria reproduce by binary fission.
Budding and Hydras-
Hydras are a type of freshwater cnidarian related to jellyfish, sea anemones and corals. Hydras reproduce asexually by developing small, genetically identical polyps that protrude from the parent. These polyps break off from the parent to form a new organism in a process called "budding."
Parthenogenesis and Copperheads- Though most of the organisms that use asexual reproduction are invertebrates, several species of vertebrate animals do make use of it. Some, like copperhead snakes, can reproduce asexually as an alternative to their typical sexual reproduction. Through a process called parthenogenesis -- literally "virgin birth" -- copperhead females can give birth to live young without having been inseminated by a male, even when males are available, according to National Geographic. In this form of parthenogenesis, the polar body, or a cell produced alongside the female's egg, acts as a sperm cell and essentially "fertilizes" the egg. Parthenogenesis has been observed in several species of reptiles, birds and sharks, and is especially common in insects.

n the picture of a planet in orbit around its star area a is double that of area b. What is true of the time the planet takes to travel A1A2 as compared to B1B2

Answers

The Kepler's laws predict the planetary motion, so there are three laws for this, namely:

1. The orbit of a planet is an ellipse with the Sun (the sun is a star!) at one of the two focus.

2. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

3. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

So, let's use second law. The Sun sweeps out equal areas during equal intervals of time means that if A = B, the time the planet takes to travel A1A2 is equal to the time the planet takes to travel B1B2, but given that A = 2B, then takes twice the time to travel A1A2 compared to B1B2.

Answer:

twice as much
