what are the methods of avoiding demagnetization​

Answers

Answer 1

[tex] \\ [/tex]

The best method to use in prevention of self-demagnetization of a permanent magnet is by use of a keeper. Keepers were also commonly known as amateurs. They help in storing magnets safely, especially those that have low coercivity ( magnets that are extremely susceptible to stray fields).

Does the mass of the objects you are charging influence the amount of electric force created in an electric field?

Answers

Explanation:

Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.

correctly explains the weight you would experience on each planet?
A. You would weigh less on planet B because it is traveling twice as
fast as planet A.
B. You would weigh the same on both planets because your mass
would adjust depending on the planet's speed.
O C. You would weigh more on planet B because it is traveling twice as

Answers

Answer:

D. You would weigh the same on both planets because their masses

and the distance to their centers of gravity are the same.

Explanation:

The above statement is true due to the fact that, the weight and masses of the individual are same in direct comparison with the distance to their center of gravity. If the weight and masses are not same, then there would have been a significant difference between the two planet.


Describe how different energy stores are changed by the boiler.
[3 marks]

Answers

Answer:

Energy can remain in the same store for millions of years or sometimes just for a fraction of a second. There are energy transfers going on all the time - whenever a system changes there is a change in the way some or all of the energy is stored.

Transferring energy

In each of these examples, energy is transferred by one of the following four types of energy transfer:

mechanical work - a force moving an object through a distance

electrical work - charges moving due to a potential difference

heating - due to temperature difference caused electrically or by chemical reaction

radiation - energy tranferred as a wave, eg light and infrared - light radiation and infrared radiation are emitted from the sun

Doing 'work' is the scientific way of saying that energy has been transferred. For example, a grazing cow, a firing catapult and a boiling kettle are all doing 'work', as energy is being transferred.

Energy flow diagrams

Diagrams can be used to show how energy is transferred from one store to another. Two examples are the transfer diagram and the Sankey diagram.

Transfer diagrams

In transfer diagrams the boxes show the energy stores and the arrows show the energy transfers.

For example, a transfer diagram for a child at the top of a slide may be:

Energy transfer diagram of a child on a slide

Gravitational energy stored in the child at the top of the slide is transferred as mechanical work done to speed up and to do work against friction. The result of this is a shift of energy from gravitational potential energy to kinetic energy and internal energy (raising the temperature of the child and the slide).

Sankey diagrams

Sankey diagrams start off as one arrow that splits into two or more points. This shows how all of the energy in a system is transferred into different stores.

Sankey diagram of a child on a slide

Sankey diagrams are really useful when the amount of energy in each of the energy sources is known. The width of the arrow is drawn to scale to show the amount of energy.

Answer: The energy from the sun is one great example of radiation. The sun emits light in a broad range of wavelengths which all contain energy. These waves are also discussed in the climate section for energy balance. The waves are emitted from the sun and travel through space and hit the earth and other planets.

At 10°C, the gas in a cylinder has a volume of 0.250 L. The gas is allowed to expand to 0.285 L.


What must the final temperature be for the pressure to remain constant? (Hint °C + 273 = K.)


282 K


284 K


323 K


248 K

Answers

Explanation :Use the formula: P1V1T1=P2V2T2
We know that we want P1=P2 so the pressure will remain constant, so we can say that: P1V1T1=P1V2T2
Plug in the values we know: P1⋅0.250L283K=P1⋅0.285LT2
(Remember that temperature must be done in Kelvin.)
Cross multiply: T2⋅P1⋅0.250L=283K⋅P1⋅0.285L
Divide both sides by P1.
T2⋅0.250L=283K⋅0.285L
T2=283K⋅0.285L0.250L
T2=323K
(This is also 50˚C.)

Why does an increase in temperature result in an increase in reaction rate?

Answers

Answer:

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.

Answer:

When we increase the temperature in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases collision between the particles and the rate of reaction.
