The magnitude of the magnetic moment due to the electron's motion is [tex]87.87 * 10^{-37}[/tex].
What is magnetic moment?The magnetic pull and direction of a magnet or other object that produces a magnetic field are referred to as the magnetic moment in electromagnetism. Things that have magnetic moments include electromagnets, permanent magnets, various compounds, elementary particles like electrons, and a number of celestial objects (such as many planets, some moons, stars, etc).
The term "magnetic moment" really refers to the magnetic dipole moment of a system, which is the portion of the magnetic moment that can be represented by an equivalent magnetic dipole or a pair of magnetic north and south poles that are only very slightly apart. The magnetic dipole component is adequate for sufficiently small magnets or over sufficiently large distances.

Taking into account the definition of kinetic energy, the kinetic energy of a 3.50kg block with a speed of 4.00 m/s is 28 J.
Definition of kinetic energyKinetic energy is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
In other words, kinetic energy is defined as the amount of work necessary to accelerate a body of a certain mass and in a position of rest, until it reaches a certain speed.
Kinetic energy is represented by the following expression:
Ec = 1/2×m×v²
where:
Ec is kinetic energy, which is measured in Joules (J). m is mass measured in kilograms (kg).v is velocity measured in meters over seconds (m/s).Kinetic energy in this caseIn this case, you know:
m= 3.50 kgv= 4 m/sReplacing in the definition of kinetic energy:
Ec = 1/2× 3.50 kg× (4 m/s)²

Owen throws the ball to Dina at 0.800 c (according to Owen), and their separation (measured in S' ) is equal to 1.80 × 10¹²m .(a) According to Dina, how fast is the ball moving?
The speed of the ball with respect to Dina is 0.800c.
A frame of reference is a set of reference points—geometric points whose positions are known mathematically and physically—that define the origin, orientation, and scale of an abstract coordinate system.
If a body does not continuously adjust its position in relation to its environment throughout the course of time, it is said to be at rest.
In frame S', Dina and Owen are at rest.
The speed of the ball with respect to Owen, u =0.800c
The speed of the frame S' with respect to frame S, v = 0.600c
Distance between Dina and Owen, L(p) = 1.8 × 10¹² m

What is the mass of a rocket 5,000m above the Moon’s surface if 84kJ
of gravitational potential energy is stored? Assume g on the Moon =
1.63N/kg.
Considering the definition of potential energy, the mass of a rocket 5,000 m above the Moon’s surface is 10.31 kg.
Potential energyPotential energy is the energy that measures the ability of a system to do work based on its position. In other words, this is the energy that a body located at a certain height above the ground has.
Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the strength of gravity. Then, the expression applied to the gravitational energy of the object is:
Ep= m×g×h
Where:
Ep is the potential energy in joules (J).m is the mass in kilograms (kg). h is the height in meters (m).g is the acceleration of the fall in m/s².Mass of the rocketIn this case, you know:
Ep= 84 kJ= 84,000 J (being 1 kJ= 1,000 J)m= ?h= 5,000 mg= 1.63 N/kg= 1.63 m/s²Replacing in the definition of gravitational potential energy:
84,000 J= m×1.63 m/s²×5,000 m
Solving:
84,000 J= m× 8,150 m/s²×m
84,000 J÷ (8,150 m/s²×m)= m

Answer:
The speed of the electron is 0.98c, given that the rest energy of an electron is 0.511MeV and the rest energy of a proton is 938MeV, with both particles having kinetic energies of 2.00MeV.
Explanation:
A particle's total energy and the rest energy follow the laws of physics and the theory of relativity. The energy of any particle is equal to mass times the speed of the light-squared relatively.
Where; E=γ.〖mc〗^2
γ is the ratio of total energy to rest energy of the particle.
m_0 is known as the rest mass of the particle.
Rest energy can be written as: E_0=〖m_0 c〗^2
γ=K/E_0 +1 (1)
γ=1/(√1-v^2/c^2) (2)
Putting the values of the electron energy into equation (1):
γ=2.00MeV/0.511MeV+1
γ= 3.91 + 1
γ=4.91
From equation (2),
γ=1/(√1-v^2/c^2)
Squaring both sides of the equation,
γ^2=1/(1-v^2/c^2)
1/γ^2 =1-v^2/c^2
v^2/c^2 =1-1/γ^2
v/c=√1-1/γ^2
Making v subject of the formula,
v=√1-1/γ^2 ×c (3)
Inserting the values into Equation 3,
v=√1-1/〖4.91〗^2 ×c
v=√1-1/24.11×c
v=√0.959×c
v=0.98×c
v=0.98c
Therefore, the speed of the electron is 0.98c.

A parallel-plate capacitor is disconnected from a battery, and the plates are pulled a small distance further apart. Do the following quantities increase, decrease, or stay the same?.
When the parallel-plate capacitors are disconnected from a battery and plates are pulled a small distance farther apart then Q remains the same, C decreases, Change in potential increases, Energy stored increases and E stays the same.
Solution:
Let's take C as the capacitance of parallel plates and Q as the Charge stored and 'd' is the distance between a plate of capacitors.
In the case of disconnection between plate capacitors, the capacitance of a parallel-plate capacitor becomes equal.
Then, charge Q remains the same i.e.
Q = εA / d = Q / Ed = Q/V
Here Q refers to the charge stored in a capacitor, E is the Electric field, V is the potential difference, and 'd' is the separation between plates.
There is an inverse relationship between potential difference and distance against the capacitance between a plate of the capacitor.
Similarly, the potential difference will increase when capacitance decreases.
E = V/d
While the values of V and d show a gradual decrease, E remains constant, therefore energy stored in the capacitor will be E = 1/2CV^2
The decrease in C causes an increase in V, as a result of which energy stored in the capacitor increases.

Find (a) the force on each side of the loop
The force on each side of the loop is [tex]2.26\times10^{-4}N[/tex] away from the centre .
Magnetic field at the centre of a solenoid of length 'L' having 'N' number of turns with a current 'I' is given by [tex]B=\frac{u_0NI}{L}[/tex] ...(1) where [tex]u_0[/tex] is the permittivity of free space whose value is [tex]4\pi \times10^{-7}Tm/A[/tex] .Force due to current carrying wire 'I' in a magnetic 'B' having length 'L' is given by [tex]F=BILsin\theta[/tex] ...(2) where θ is the angle between current and length of the wire .It is given that solenoid has 30.0 turns/cM which means we have given number of turns per unit length [tex]n=\frac{N}{L} =30\times10^{2}m[/tex] and carries a clockwise current of 15.0A .
Putting above values in equation (1) , we get
[tex]B=4\pi \times10^{-7}\times 30\times10^{2} \times15.0\\B=0.0565T[/tex]
The magnetic force exerted due to their magnetic field on the sides of the loop will be away from the center of loop and is given by equation (2) .
It is given that current in the loop is 0.200 A and length of the each side of the loop is 2.00 cm [tex]=2\times10^{_2}m[/tex] and plane of the loop perpendicular to the magnetic field of the solenoid.
Putting above values in equation (2) , we get
[tex]F=0.0565\times0.2\times2\times10^{-2}\times sin90\\F=2.26\times10^{-4}N[/tex]
Direction of force is found by Fleming' Left Hand rule which states that when the thumb, index finger and middle finger of the left hand are placed perpendicular to each other, the thumb points in the direction of the magnetic force, the index finger points in the direction of the magnetic field, and the middle finger points in the direction of the flow.
According to Fleming's left hand rule, the magnetic force exerted due to their magnetic field on the sides of the loop will be away from the center of loop and is given by equation (2) .

A 2 kg block of cheese is in an elevator accelerating down at a rate of 1.5 m/s².
What is the normal force on the cheese?
a spring is compressed by 1 cm when a force of 5.0N is applied. what is the potential energy stored in the spring when it is compressed by 10.cm
The potential energy stored in the spring is 0.025 J.
What is potential energy stored in a spring?This is the energy stored in a spring when its is stretched or compressed through a certain length.
To calculate the potential energy stored in a spring, we use the formula below.
Formula:
E = Fe/2............... Equation 1Where:
E = Potential energy of the springF = Force applied to the springe = Extension or CompressionFrom the question,
Given:
F = 5 Ne = 1 cm = 0.01 mSubstitute these values into equation 1
E = 5×0.01/2E = 0.025 JHence, the potential energy stored in the spring is 0.025 J.
