Explain/Describe how atoms in domains determine whether a material is magnetic or not. (Please help this is due today)
Answers
Answer:
In a material, the magnetic behavior depends on the alignment of magnetic moments of the atoms. Magnetic moments are generated by the motion of the electrons in the atoms. When the magnetic moments of atoms in a material are aligned in a specific pattern, it creates a magnetic field which results in the material being magnetic.
In many materials, the magnetic behavior arises due to the alignment of magnetic domains, which are regions of atoms with magnetic moments aligned in the same direction. When many domains with aligned magnetic moments are present in a material, the material becomes magnetic.
The magnetic behavior of a material depends on the number of electrons and the arrangement of those electrons in the atoms. In particular, for an atom to have a magnetic moment, it must have unpaired electrons, meaning electrons that are not paired with another electron with the opposite spin. When these unpaired electrons in the atoms are aligned, they generate a magnetic moment. If all electrons are paired, there will not be a net magnetic moment, so the material will not be magnetic.
So, in summary, the magnetic behavior of a material is determined by the alignment of magnetic moments of atoms. When the magnetic moments of many atoms in a material align in the same direction, it creates a magnetic field, leading to a material being magnetic. This alignment is usually present in magnetic domains consisting of atoms with unpaired electrons.

J=A P
AP=mvf-mvi
Answers
The impulse of the car after hitting is 98860.8 kg.m/s
In physics, the term "impulse" is used to characterize or measure the impact of force operating gradually to alter an object's motion. It is often stated in Newton-seconds or kilograms per second and is denoted by the symbol J.
J = m ( v-u)
where, m = 2168 kg
u = 50 m/s
v = 4.4 m/s
J = 2168 ( 4.4 - 50)
J = 2168(45.6)
J = 98860.8 kg.m/s
since the final velocity is decreasing the impulse is a vector term thus a negative sign will also be included in this.

Answers
B) A pendulum is a mass suspended on the bottom of a string.
A pendulum is a simple mechanical device that consists of a mass (known as the bob) suspended from a fixed point by a string, wire, or rod. When the bob is pulled to one side and released, it swings back and forth under the influence of gravity, forming a regular pattern of motion. The time it takes for the pendulum to complete one full swing (i.e., from one extreme position to the other and back again) is known as its period. The period of a pendulum is affected by the length of the string and the strength of gravity. The longer the string, the longer the period, and the stronger the gravity, the shorter the period.Pendulums have a wide range of practical applications, such as timekeeping, as seen in grandfather clocks. They are also used in scientific experiments to measure time intervals and gravitational acceleration.

Ender and Shen are flying at each other during a battle in space. Ender weighs 70 kg and Shen weighs 60 kg. When the two collide, they hold on to each other and move with a velocity 3 of 5 /. What are Ender’s and Shen’s initial velocities in /?
Answers
Ender's initial velocity was approximately 61.43 m/s, and Shen's initial velocity was approximately -100 m/s
Solution on the Space Collision Velocity problemTo solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of a closed system remains constant if no external forces act on it. We can write the equation as follows:
m1v1 + m2v2 = (m1 + m2)vf
where m1 and m2 are the masses of Ender and Shen, respectively, v1 and v2 are their initial velocities, vf is their final velocity after the collision, and we assume that the collision is perfectly elastic, which means that no kinetic energy is lost.
Substituting the given values, we get:
(70 kg)(v1) + (60 kg)(-v2) = (70 kg + 60 kg)(5 m/s)
Simplifying and solving for v1, we get:
v1 = [(70 kg + 60 kg)(5 m/s) + (60 kg)(-v2)] / 70 kg
v1 = (650 m/s + 60 kg v2) / 70 kg
Since we don't know the initial velocity of Shen, we cannot solve for v2 directly. However, we can use the fact that the two hold onto each other after the collision, which means that they move with the same final velocity vf. Thus:
vf = (m1v1 + m2v2) / (m1 + m2)
5 m/s = (70 kg v1 + 60 kg v2) / (70 kg + 60 kg)
Substituting the expression we obtained for v1 in terms of v2, we get:
5 m/s = [70 kg ((650 m/s + 60 kg v2) / 70 kg) + 60 kg v2] / (70 kg + 60 kg)
Simplifying and solving for v2, we get:
v2 = -100 m/s
Substituting this value in the expression we obtained for v1, we get:
v1 = (650 m/s + 60 kg (-100 m/s)) / 70 kg
v1 = 4300 / 70 m/s
v1 = 61.43 m/s
Therefore, Ender's initial velocity was approximately 61.43 m/s, and Shen's initial velocity was approximately -100 m/s.

Answers
The displacement of the object is 2 meters.
To determine the displacement of the object, we need to consider the change in position from the initial position to the final position.
Given:
Initial position = 0 meters
Final position = 2 meters
Calculate the displacement:
Displacement = Final position - Initial position
Displacement = 2 meters - 0 meters
Displacement = 2 meters
Therefore, the displacement of the object is 2 meters.
Explanation:
The position-time graph shows the position of an object over a specific time interval. In this case, the graph shows that the object starts at a position of 0 meters and ends at a position of 2 meters. The displacement of the object is the change in position from the initial point to the final point.
In this context, the displacement of 2 meters indicates that the object has moved 2 meters to the right or in the positive direction from its initial position. The negative and positive signs on the graph indicate the direction of motion, where positive values represent motion in one direction and negative values represent motion in the opposite direction.
The time interval is not directly related to the displacement calculation. It simply represents the duration of the object's motion. To determine the displacement, we only need to consider the initial and final positions, which in this case result in a displacement of 2 meters.

Answers
Answer:
Explanation:
The lift force will have a vertical component equal to the weight of the plane and a horizontal component sufficient to supply the needed centripetal accleration.
R = 8.01 mi = 12891 m
ω = 2π/T = 2π/(0.106(3600)) = 0.016465 rad/s
F = m√(g² + (ω²R)²)
F = 8930√(9.81² + (0.016465²(12891))²)
F = 8930√(9.81² + 3.49²)
F = 92,996.480...

A farmer after a successful harvest brings his product home using a crate. To the crate and the harvest with total mass of 50.0 kg, he exerts a force of 1.20 x 102 N by pulling on the rope.
A) How much work does he do on the crate if the rope is horizontal to the ground and he pulls the crate 5.00 m?
B) How much work does he on the crate if the rope makes an angle of 30.0 degrees with the horizontal and pulls the sled the same distance?
Answers
work = force x distance x cos(theta)
where force is the magnitude of the force applied, distance is the displacement of the crate, and theta is the angle between the force and the displacement. In this case, theta is 0 degrees because the force is in the same direction as the displacement.
Substituting the given values, we get:
work = (1.20 x 10^2 N) x (5.00 m) x cos(0 degrees)
work = 600 J
Therefore, the farmer does 600 J of work on the crate when the rope is horizontal to the ground.
B) When the rope makes an angle of 30.0 degrees with the horizontal, the force the farmer exerts is at an angle of 30.0 degrees to the displacement of the crate. Therefore, the work done by the farmer on the crate can be calculated using the same formula:
work = force x distance x cos(theta)
but this time, theta is 30.0 degrees.
Substituting the given values, we get:
work = (1.20 x 10^2 N) x (5.00 m) x cos(30.0 degrees)
work = (1.20 x 10^2 N) x (5.00 m) x 0.866
work = 519 J
Therefore, the farmer does 519 J of work on the crate when the rope makes an angle of 30.0 degrees with the horizontal.

Calculate the reading shown on the balance.
Answers
Based on the mass of the liquid and the mass of the cylinder, the reading shown on the balance is 1.593 kg.
What is the reading on balance?To calculate the reading shown on the digital balance, we need to first find the mass of the liquid in the cylinder, and then add it to the weight of the empty cylinder.
The volume of the liquid can be found using the formula for the volume of a cylinder:
V = πr²h
where;
r is the radius of the cylinder, and h is the depth of the liquid.
Substituting the given values, we get:
V = π x (3.5 cm)² x 12.0 cm
= 1486.96 cm³
We need to convert the volume from cubic centimeters to cubic meters to use the density of the liquid in kilograms per cubic meter:
V = 1.48696 x 10⁻³ m^3
The mass of the liquid can be found using the formula:
mass = density x volume
Substituting the given values, we get:
mass = 900 kg/m³ x 1.48696 x 10⁻³ m³
= 1.33826 kg
Therefore, the reading shown on the digital balance is:
mass of empty cylinder + mass of liquid
mass of empty cylinder = 2.5/9.81
mass of empty cylinder = 0.2548 kg
reading shown on the digital balance = 0.2548 kg + 1.33826 kg

When two light bulbs are connected in series, the resistance in the circuit is increase compared to that with one lightbulb. The increased resistance opposes the flow of current so far fewer electrons pass per second , transferring less energy. The lightbulbs are therefore not as bright as In a circuit with same voltage but only one bulb.
However, when Two lightbulbs are connected in parallel, each loop behaves like a separate circuit . The resistance in each branch is the same as if there were just one light bulb in the whole circuit.there is the same current in each branch of the circuit ,so the bulbs Will light up with the same brightness as a single bulb circuit. The energy stored in the battery will decrease twice as quickly and battery will run out faster than I series circuit.
6) explain the advantages and disadvantages of arranging components in series or parallel.
Answers
Advantages of Components Arranged in Series:
1. Increased resistance: Connecting components in series increases the overall resistance in the circuit. This can be advantageous in situations where you want to limit the flow of current or control the amount of power being dissipated.
2. Voltage sharing: In a series circuit, the total voltage of the power supply is divided among the components. This can be useful when you want to ensure that each component receives a specific voltage.
3. Current consistency: The current remains the same throughout the series circuit, which can be beneficial when you need to ensure a consistent current flow through multiple components.
Disadvantages of Components Arranged in Series:
1. Reduced brightness or performance: As mentioned in the question, when light bulbs are connected in series, the increased resistance reduces the flow of current, resulting in dimmer bulbs or reduced performance in other electrical devices.
2. Single point of failure: If one component in a series circuit fails, it can disrupt the entire circuit and cause all components to stop functioning.
Advantages of Components Arranged in Parallel:
1. Brightness and performance: When components such as light bulbs are connected in parallel, each component receives the full voltage, resulting in brighter bulbs and better performance in other devices.
2. Redundancy: In a parallel circuit, if one component fails, the other components can continue to function independently. This provides redundancy and ensures that the failure of one component does not affect the others.
3. Increased current capacity: Parallel arrangement allows the circuit to handle higher currents, which can be useful in situations where high power or heavy loads are required.
Disadvantages of Components Arranged in Parallel:
1. Increased complexity: Parallel circuits require more wiring and connections, which can make the circuit more complex and harder to manage.
2. Higher cost: Parallel circuits may require more components and wiring, resulting in higher costs for materials and installation.
It's important to consider the specific requirements and constraints of the application when deciding whether to arrange components in series or parallel. Each configuration has its advantages and disadvantages, and the choice depends on factors such as desired current flow, voltage distribution, and reliability.I
Equation of path of projectile is y=x(1-x)
Answers
The equation of the path of a projectile is y = x(1 - x). Projectile motion is the movement of an object in a parabolic trajectory as a result of being propelled or released under the influence of gravity. A projectile, in simple terms, is any object that is launched into the air, such as a bullet, a baseball, or a rock. It's important to note that the parabolic trajectory is due to the force of gravity acting on the object.
To better understand projectile motion, we must first examine the horizontal and vertical components of motion. The horizontal component of motion is constant, indicating that there is no acceleration in that direction. The vertical component, on the other hand, has acceleration because of gravity. The parabolic trajectory is the result of these two components of motion.As the projectile is launched, it travels a certain distance horizontally before beginning to descend as a result of gravity's influence, resulting in a parabolic path.The general formula for the trajectory of a projectile in two dimensions is given by:y = xtanθ - (gx²) / 2(v₀cosθ)²Where:y is the vertical distance covered by the projectilex is the horizontal distance covered by the projectileθ is the angle of projectiong is the acceleration due to gravityv₀ is the initial velocity of the projectile In the case of the given equation, y = x(1 - x), the path of the projectile will be a parabolic trajectory with a vertex at x = 0.5 and y = 0.25. The equation represents the projectile's vertical distance, y, as a function of its horizontal distance, x. It is crucial to note that the projectile's initial velocity and angle of projection are not considered in this equation.For such more question on acceleration

Let T is the period of a pendulum. The SI unit of time is seconds (s).
It depends on the acceleration of gravity, g, and the length of the pendulum, l.
