what are the methods of avoiding demagnetization
[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).

Why is it safer to collide with a soft cushion than a hard surface?
Answer:
Impulse is force multiplied by time; and together, the product must be 1 unit. A collision with soft ground will result in the 1 unit of impulse by a larger time and a smaller force (compared to the small time and a large force for the hard floor).

A dipole is centered at the origin, with its axis along the axis, so that at locations on the axis, the electric field due to the dipole is given by E = (0, 1/4 pi epsilon_0 2qs/gamma^3, 0) v/m The charges making up the dipole are q_1 = +4 nC and q_2 = nC, and the dipole separation is s = 8 mm. What is the potential difference along a path starting at location p_1 = (0, 0.04, 0) m and ending at location P_2 = (0, 0.05, 0) m?
Answer:
Explanation:
Given that:
[tex]q_1 = + 4nC \\ \\ q_2 = -4nC \\ \\ q = 4nC[/tex]
[tex]P_1 = (0,0.04,0) m\\\\ P_2 = (0,0.05,0) m[/tex]
As [tex]q_1[/tex] [tex]\text{is nearer to }[/tex][tex]P_1 \& P_2[/tex] then [tex]q_2,q_1[/tex] [tex]\text{is positive, Thus}[/tex], [tex]E \limits^{\to}[/tex][tex]\text{ will be along the positive X-axis.}[/tex]
Recall that:
[tex]E ^{\to} = \dfrac{-dV}{dr}\implies E_y = \dfrac{-dV}{dy} \\ \\ = \int^{P_2}_{P_1}dV = -\int \limits ^{(0.05)}_{(0.04)}E_y \ dy \\ \\ \implies (V_{P_2}}-V_{(P_1)}) = \dfrac{-2q_5}{4 \pi \varepsilon _o} \int \limits ^{(0.05)}_{(0.04)} \dfrac{dy}{y^3} \\ \\ \implies (V_{P_2}}-V_{(P_1)}) = \dfrac{-2q_5}{4 \pi \varepsilon _o} \Big[ \dfrac{-1}{2y^2} \Big]^{0.05}_{0.04} \\ \\ \implies (V_{P_2}}-V_{(P_1)}) = \dfrac{q_5}{4 \pi \varepsilon _o} \Big[\dfrac{1}{y^2}\Big] ^{0.05}_{0.04}[/tex]
[tex]\\ \\ \implies (V_{P_2}}-V_{P_1}) = \dfrac{(4\times 10^{-9})(8\times 10^{-3})}{4 \pi (8.854 \times 10^{-12})} \Big [\dfrac{1}{(0.05)^2}-\dfrac{1}{(0.04)^2} \Big ]V \\ \\ (V_{P_2}}-V_{P_1}) = \mathbf{-64.71 \ volts}[/tex]

What is the kinetic energy of a 0.500 kg toy car moving at a state of 1.50 m/s
Answer:0.563
Explanation:
The kinetic energy produced in a toy car is equal to 0.563 J.
What is the kinetic energy and potential energy?The energy exhibited by a moving body because of its motion is said to be its kinetic energy. Work should be done which can change the kinetic energy of a moving object.
The kinetic energy of a moving object can be determined from the formula mentioned below:
K.E. = ½mv² where ‘m’ and ‘v’ is the mass, velocity of the object.
Potential Energy (P.E.)is energy that is stored in an object due to its position and can be expressed as P.E = mgh where h, m, and g are the height, mass, and gravitational acceleration respectively.
Given, the mass of the toy car =, m = 0.500 Kg
The velocity of the toy car, v = 80 m/s
The kinetic energy = (1/2)× 0.500 ×(1.50)²
K.E. = 0.563 J

An educated person has the ability to think clearly and independently and has good judgement.
What is Education?Education is defined as purposeful activity directed towards achieving some objective, such as the dissemination of knowledge or the promotion of skills and character traits, whose aims include the development of understanding, rationality, kindness and honesty.
There are three main types of education which are as follows:
Formal, Informal and Non-formal.
The specialty of education is that it is pre-determined and pre-planned. It is regular and spatial i.e. time bound and regulated by the institutional. Proper education improves people's understanding of the world around them which make them less susceptible to the influence of others
Thus, an educated person has the ability to think clearly and independently and has good judgement.

The 25-mph zone is 150 yards long. How much time did the student save (in seconds) by speeding past the school
Answer:
Time = 12.27seconds
Explanation:
Given
Speed = 25miles/hour
Distance = 150 yards = 150(0.000568182)miles
Distance (in miles) = 0.0852273miles
Get the time
Speed = Distance/Time
Time = Distance/Speed
Time = 0.0852273/25
Time = 0.0034hours
Time = 0.0034 * 3600secs
Time = 12.27seconds
can you give me an example about radiation
Explanation:
A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles.
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.

A 20 kg cart moving at 4 m/s has how much momentum?
40 kg*m/s
40 kg*m/s
5 kg*m/s
5 kg*m/s
80 kg*m/s
Answer:
We conclude that the required momentum is 80 kgm/s.
Explanation:
Given
Mass m = 20 kgVelocity v = 4 m/sTo determine
The momentum p = ?
Important Tip:
The momentum of an object is the product of mass and velocity.We can determine the momentum using the formula
[tex]p = mv[/tex]
where
p is the momentumm is the massv is the velocitynow substituting m = 20 and v = 4 using the equation
[tex]p = mv[/tex]
[tex]p = (20) (4)[/tex]
[tex]p = 80[/tex] kg m/s
Therefore, we conclude that the required momentum is 80 kgm/s.
The momentum of the moving cart is 80kgm/s.
HOW TO CALCULATE MOMENTUM:
The momentum of a body can be calculated by multiplying the mass of that body by its velocity. That is;Momentum (p) = mass (m) × velocity (v)
According to this question, a 20kg cart moving at 4 m/s will have a momentum as follows:Momentum (p) = 20kg × 4m/s
Momentum (p) = 80kg*m/s.
Therefore, the momentum of the moving cart is 80kgm/s.Learn more at: https://brainly.com/question/17173143?referrer=searchResults
