What is Kirchoff's current law ?
Kirchhoff's current law states that the sum of the currents entering any node in a circuit must equal the sum of the currents leaving that node. In other words, the total current flowing into a node or junction in a circuit must equal the total current flowing out of that node.
Based on Kirchhoff's current law, the current leaving I_bat must be equal to current entering R.
Based on the diagram, the current entering R = I₁, so the current that might have left the I_bat is I₁ is as well.

what is the physics behind why electric parallel plates move from positive to negative
Answers
The physics behind the movement of electric charges between parallel plates is based on the principles of electrostatics. Electric charges are either positive or negative, and they are affected by electric fields.
Electric fields are created by a difference in electric potential, which is measured in volts. When a voltage is applied to a set of parallel plates, the charges within the plates will be affected by the electric field, and will move in response to it.
What are electric parallel plates?When a voltage is applied to a set of parallel plates, the positive charges in the plate connected to the positive voltage will be attracted to the negative voltage, while the negative charges in the plate connected to the negative voltage will be attracted to the positive voltage.
The movement of charges between the plates is also affected by the presence of any obstacles or resistances in the electric field, such as resistance in the wire. This can slow down the movement of charges and result in a decrease in the current flowing through the circuit.
In all, the movement of charges between electric parallel plates is the result of the electric field created by a difference in electric potential, and the movement of charges is called drift velocity. The movement is also affected by the presence of resistance.

Answer in units of J.
Answers
Part 1: the final angular speed is 0.64 + 0.86 = 1.50 rad/s. Substituting the values, 1.05 J.
What is angular speed?Angular speed is the rate of change of angular displacement of a body over a period of time. It is also known as rotational speed and is usually measured in revolutions per minute (RPM) or radians per second (rad/s).
Part 1:
The angular speed is given by the formula w = Iα, where w is the angular speed, I is the moment of inertia and α is the angular acceleration. Since the moment of inertia is constant, the change in angular speed is given by Δw = ΔIα.
The change in moment of inertia is given by ΔI = mr2, where m is the mass of the objects and r is the change in radius.
So, the change in angular speed is given by Δw = mr2α.
Substituting the given values,
Δw = (3 kg)(1 m - 0.3 m)2(0.64 rad/s)
Δw = 0.86 rad/s
Therefore, the final angular speed is 0.64 + 0.86 = 1.50 rad/s.
Part 2:
The change in kinetic energy of the system is given by ΔK = ΔIw2/2.

Assuming that we could equally divide all the world's wealth and assets among everyone, why would stratification soon be evident among
societies again? Use Functionalism, Conflict Theory, and/or Interactionism to support your answer.
Post and respond to at least two other posts.
Answers
Answer:
Explanation:
Functionalism: According to functionalism, social inequality is necessary for the smooth functioning of society. This means that even if all the world's wealth and assets were equally divided, people's skills, abilities, and efforts would still differ, leading to differences in income and wealth. Moreover, social positions that require more education, training, and skills would still be rewarded more highly than those that require less. Therefore, some people would still be motivated to achieve more than others and occupy higher social positions. Additionally, some people might not want to work hard and would be content with their share, while others might want to invest their share and accumulate more wealth. This would lead to differences in wealth and income over time, leading to the re-emergence of social stratification.
Conflict Theory: According to conflict theory, social inequality is the result of the struggle for power and resources between different social groups. Even if all the world's wealth and assets were equally divided, some people or groups would still try to monopolize the resources and accumulate more wealth and power than others. For example, some people might try to control the means of production, such as land, factories, and capital, while others might try to control the distribution of goods and services, such as markets, transportation, and communication. Moreover, some people might have more social and cultural capital, such as education, networks, and prestige, which would give them an advantage in achieving their goals. Therefore, social stratification would still exist, but in different forms and with different justifications.
Interactionism: According to interactionism, social inequality is the result of the symbolic meanings and interpretations that people attach to wealth, status, and power. Even if all the world's wealth and assets were equally divided, people would still have different attitudes, values, and beliefs about them, which would affect their behavior and interactions. For example, some people might feel more entitled to a higher share of the wealth and assets because of their race, gender, religion, or nationality, while others might feel less entitled or even resentful. Moreover, some people might use their wealth and assets as symbols of their identity, status, and prestige, while others might reject them as meaningless or corrupt. Therefore, social stratification would still exist, but in different symbolic forms and meanings.
Response to Post 1:
I agree with your analysis from the perspective of functionalism.

This would lead to differences in wealth and income over time, leading to the re-emergence of social stratification. Additionally, social positions that require more education, training, and skills would still be rewarded more highly than those that require less. Therefore, the functionalist perspective suggests that social inequality is not only inevitable but also necessary for the smooth functioning of society.

What is resolution of vectors?The process of splitting a vector into its components is called resolution of the vector. The vectors are splitted into vertical and horizontal component.
For the first displacement;
The vertical component = - 150 sin45 = -106.1 m
The horizontal component = - 150 cos 45° = -106.1 m
For the second displacement;
The vertical displacement = - 85sin90 = -85
The horizontal component = 0
For the third displacement;
The vertical displacement = 550 sin55 = 450.5
The horizontal displacement = 550 cos 55 = 315.5
Sum of vertical component = 450.5-85-106.1 = 263.4
sum of horizontal component = 315.5 -106.1 = 209.4

300m . He claps his hands and hears an echo calculate the time interval of him hearing his echo
Answers
The time interval between the man clapping and hearing his echo is approximately 1.75 seconds.
What do you mean by echo?An echo is a repetition or reflection of a sound or signal. It can be caused by sound waves bouncing off a surface, signal interference, or the repetition of a message in communication.
The speed of sound in air at room temperature is approximately 343 meters per second. When a person claps, the sound waves propagate outward in all directions and reach the school building, where they bounce off and return to the person as an echo. The time it takes for the sound to travel the distance to the building and back to the person is the time interval between the clap and the echo.
To calculate the time interval, we can use the following formula:
time = distance / speed
where distance is the total distance traveled by the sound (twice the distance from the person to the school building), and speed is the speed of sound in air.
distance = 2 x 300m = 600m
speed = 343 m/s
time = 600m / 343 m/s = 1.75 seconds (rounded to two decimal places)
Therefore, the time interval between the man clapping and hearing his echo is approximately 1.75 seconds.

Calculate the speed the: W< 1 >E S 4.2.1 Canon collides with the barrier
Answers
The cannon will completely stop when it collides with the barrier.
To calculate the speed at which the cannon collides with the barrier, we can follow these step-by-step calculations:
Determine the initial momentum of the system.
Since the cannon is initially stationary, the initial momentum is zero.
Apply the conservation of linear momentum.
According to the principle of conservation of linear momentum, the initial momentum of the system (zero) is equal to the final momentum of the system. The final momentum is the momentum of the cannon after firing.
Calculate the final momentum of the system.
Let's assume the mass of the cannon is represented by 'm' and the final velocity of the cannon is represented by 'v'. The final momentum of the system is given by: final momentum = m × v.
Set up the equation.
Since the initial momentum is zero, we have: 0 = m × v.
Solve for the final velocity of the cannon.
Dividing both sides of the equation by 'm', we get: v = 0.
Interpret the result.
The calculation shows that the final velocity of the cannon is zero. This means that the cannon comes to a complete stop when it collides with the barrier.

The average speed of the elderly woman walking around the shopping center is 1.80 km/h.
To calculate the average speed of the elderly woman, we can use the formula for velocity, which is equal to the distance traveled divided by the time taken. In this case, the distance traveled is 0.30 km and the time taken is 10 minutes. However, average speed is generally expressed in units of distance per unit of time, so we need to convert minutes to hours.
There are 60 minutes in one hour, so 10 minutes is equal to 10/60 = 1/6 hours.
Now we can calculate the average speed by dividing the distance traveled (0.30 km) by the time taken (1/6 hours):
Average speed = 0.30 km / (1/6 h)
= 0.30 km * (6/1 h)
= 1.80 km/h
Therefore, the average speed of the elderly woman walking around the shopping center is 1.80 km/h.
