Why must you emove magnet slowly from alternating current

Alternating current changes the orientation of the electromagnetic field by rapidly switching directions, helps to demagnetization.

<h3 /><h3>What is the process of Demagnetization by AC current?</h3>

Alternating current changes the orientation of the electromagnetic field by rapidly switching directions.

Because providing an electrical field (electromagnet) is one technique to create a magnet, it stands to reason that you can use alternating current to remove magnetism as well.

To do this, an alternating current (AC) current is sent through a solenoid. Begin with a greater current and gradually lower it until it is zero.

The magnetic dipoles strive to position themselves according to the field, but because it changes, they become randomized. Due to hysteresis, the material's core may retain a modest magnetic field.

Hence, alternating current changes the orientation of the electromagnetic field by rapidly switching directions, helps to demagnetization.

Hey there!
Alright, it looks like you've got the second question on the top right, but I can't figure out the answer you've got for the first.
Using Newton's Second Law Of Motion, we have:
F = ma
We plug in our values:
F = 5(1)
That would give us 5 Newtons of force.
For the last one:
Even if two balls are given the same acceleration, the determining factor is <em>weight.</em> If a ball is lighter, it needs less acceleration to go faster. If it's larger, it needs more to make it go at that same speed. That's why that 5 newtons makes sense because it's 5 kilograms as opposed to 0.6 kilograms. It's heavier, and needs more force.
Hope this helped!

Which of the following is a consequence of the special theory of relativity?
aleksandr82 [10.1K]

Answer:

D.

Explanation:

Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.

Although the acceleration due to gravity is the same on all objects, why do a flower petal
Inessa [10]

We know that acceleration due to gravity is the same for all objects. But if we drop a flower petal and a hammer from the same height, the hammer falls faster. Why does this happen?

Let me try to explain. The petal falls slower as the resistance it faces by air slows it down much more. Even though the hammer is also affected by this resistance, the speed decrease is negligible due to its weight.

To simplify, a petal is much lighter than a hammer. Even though gravity accelerates them at the same speeds, the petal slows down due to air resistance but the hammer doesn't, as its weight counteracts the air resistance.

I may be confusing at times, so please ask me if you want anything clarified :)

Hope this helps you!

On Earth, the number flux of solar neutrinos from the p-p chain is:
Nataly [62]

Answer:

Explanation:

The volume of the tank = 50 kton

50 kton = 5 × 10⁷ kg

Since 18 grams of water will contain: 10 electrons × 6.023 × 10²³

Then;

5× 10⁷ kg will contain ( \dfrac{5 \times 10^7 \times 10^3}{18}) \times 10 \times 6.023 \times 10^{23}

= 1.67 × 10³⁴ electrons

(b)

Suppose:

f_{neutrino} = \dfrac{2f_o}{26.2 MeV} = 6.7\times 10^{10} \ s^{-1} cm^{-2}

Then;

10⁻⁶ of f_{neutrino} = 6.7 \times 10^{10} \times 10^{-6} \ s^{-1} cm^{-2}

=6.7 \times 10^{4}\ s^{-1} cm^{-2}

Thus, the number of high energy neutrinos which will interact with water is:

= 6.7 \times 10^4 \times \sigma

= 6.7 \times 10^4  \times 10^{-43}

= 6.7 \times 10^{-39} s^{-1}

For  1.67 × 10³⁴ electrons, the detection rate is:

6.7 \times 10^{-39}  \times 1.67 \times 10^{34}

= 11.19 \times 10^{-5} \ s^{-1}

= 9.668 per day
