A traditional economy is a system that is based on honorable customs, history, and beliefs. Tradition guides economic decisions, such as production and distribution. Traditional economies depend on agriculture, fishing, hunting, gathering or some combination above. They use exchange instead of money. Most traditional economies operate in emerging markets and developing countries. They are often in Africa, Asia, Latin America and the Middle East. But you can find scholarships from traditional economies scattered all over the world. Economists and anthropologists believe that all other economies started out as traditional economies. Thus, they expect the remaining traditional economies to evolve into market, command or mixed economies over time.

the very act of observing a particle has a dramatic effect on its behaviour why do you think this is the case
Answers
Answer:
Explanation:
In the microscopic world of quantum mechanics, particles don't behave like familiar everyday objects. They can exist in multiple states simultaneously and behave as both particles and waves. When we try to measure or observe a particle, we typically use light or other particles to interact with it. However, this interaction can disturb the particle's state. Imagine trying to measure the position of an electron using light. Light consists of photons, and when photons interact with the electron, they transfer energy to it. This energy exchange causes the electron's position and momentum to become uncertain. The more precisely we try to measure its position, the more uncertain its momentum becomes, and vice versa. This is known as the Heisenberg uncertainty principle.
So, the act of observing a particle disturbs its state because the interaction between the observer and the particle affects its properties. The very act of measurement or observation introduces a level of uncertainty and alters the particle's behavior. It's important to note that this behavior is specific to the quantum world and doesn't directly translate to the macroscopic world we experience in our daily lives. Quantum mechanics operates at extremely small scales and involves probabilities and uncertainties that are not typically noticeable in our macroscopic observations.

What happens to the number of waves when you change the light from green to red?
Increase
decrease
remain the same
there are zero waves
Answers
When you change the light from green to red, the number of waves remains the same.
Light waves behave similarly throughout the electromagnetic spectrum. Depending on the nature of the item and the light's wavelength, a light wave can be transmitted, reflected, absorbed, refracted, polarized, diffracted, or dispersed when it strikes a surface.
The number of waves doesn't vary when the light changes from green to red. The distance between each wave's consecutive peaks, or wavelength, determines the color of light. Red and green light both have waves with a set number of peaks and troughs per unit of time, despite green light having a shorter wavelength. As a result, the number of waves is unaffected by changing the colour of the light.

If dx denotes the change in position of an object and dt denotes the corresponding time interval, then instantaneous velocity is given by:
Answers
Answer:
\(Velocity=\frac{dx}{dt}\)
Explanation:
Remember that instantaneous velocity is just a measure to know the velocity that any object has at any point given in time, so we just need to know the distance it has travel, which would be the change in position, and the time it took that change in position to occurr, this means distance by time, so we just divide dx by dt and we have the solution for instantaneous velocity.
If a change in position as denoted by \(dx\) and \(dt\) change in time, the instantaneous velocity will be given by,
\(v = \dfrac {dx}{dt}\)
What is Velocity?It can be defined by the change in position of the object over time. This is a vector quantity. Vector quantity is a quantity that has both magnitude and direction.Instantaneous velocity:The velocity of the object at a point of time is known as instantaneous velocity. Instantaneous velocity can be calculated by the ratio of change in position to the elapsed point of time.
\(v = \dfrac {dx}{dt}\)
Where,
\(v\) - instantaneous velocity
\(dt\) - change in distance (position)
\(dt\)- change in time
Therefore, if a change in position as denoted by \(dx\) and \(dt\)change in time, the instantaneous velocity will be given by,

Answers
According to the question the tension in each wire is 1.96 N.
What is tension?Tension is a term that describes the psychological and physical state of a person or system in which there is a high degree of stress, uncertainty, and anxiety. It is often associated with conflict and is often experienced when individuals or groups feel threatened or constrained in some way. Tension can be experienced in a variety of different contexts, from interpersonal relationships to the workplace. It can result from a variety of different factors, including a lack of communication, conflicting goals or expectations, and unmet needs.
The body is in equilibrium when the sum of all forces acting on it is equal to zero. In this case, the forces acting on the metal tube are the two wires and the weight of the tube due to gravity.
The tension in each wire is equal to the weight of the tube divided by the length of the tube. This is because the tube is suspended horizontally, so the forces in each wire must be equal in order to keep the tube in equilibrium.
Therefore, the tension in each wire is:
T = (9 kg × 9.8 m/s2) / (5 cm × 0.01 m)
= 1.96 N
Therefore, the tension in each wire is 1.96 N.

Is it possible for the displacement to be greater than the distance traveled? Explain.
Answers
Answer:
It is not possible for the magnitude of displacement of an object to be greater than the distance that this object travelled.
Explanation:
The displacement of an object is difference between its final and initial position. On the other hand, the distance that an object travelled would be equal to the length of the path that this object takes when it moved from its initial position to the final position.
The distance an object travelled and the magnitude (length) of its displacement each represent the length of a path between the initial and final position:
The distance travelled can represent the length of any path between these two points. On the other hand, the magnitude of displacement can only represent the length of the line segment that directly connects the two points.On a flat surface, the shortest path between two points is always going to be a straight line segment connecting the two points. If these two points are the initial and final position of the object, the magnitude of displacement would simply represent the length of that straight line segment. It is not possible for the distance travelled to be any shorter than the shortest path between the two points. Therefore, the displacement of an object would always be less than or equal to the distance it travelled.

As a derivative of behaviorism, the learning principles that are the basis for behavior modification are considered empirically valid.
The concepts of operant conditioning, which were created by behaviourist B.F. Skinner, are the foundation of behaviour modification, a therapeutic strategy. In order to increase desired behaviours and decrease undesirable ones, it entails altering an individual's behaviour through reinforcement, punishment, or extinction.
The concepts of operant conditioning have been thoroughly investigated and put to the test through empirical research, and it has been discovered that they are successful in changing behaviour. As a result, because they are backed by research, the learning principles that underlie behaviour modification are regarded as empirically valid.

A 5 kW, 230 V motor draws a current of 24 A from the supply. Determine the efficiency of this motor.
Answers
The efficiency of motor is 90.58%.To determine the efficiency of the motor, we need to calculate the input power and the output power, and then divide the output power by the input power
The input power can be calculated using the formula:
Input Power = Voltage × Current
Given that the voltage is 230 V and the current is 24 A, we have:
Input Power = 230 V × 24 A
Input Power = 5520 W (or 5.52 kW)
The output power of the motor is given as 5 kW (since it is a 5 kW motor).
Now, we can calculate the efficiency:
Efficiency = (Output Power / Input Power) × 100%
Efficiency = (5 kW / 5.52 kW) × 100%
Efficiency ≈ 90.58%

It is given that,
Initial volume of the plastic box is 2 m³
It is then submerged below the surface of a liquid and its volume decreases to 1.96 m³
We need to find the volume strain on the box. It is defined as the change in volume divided by the original volume. So,
\(\delta V=\dfrac{V_f-V_i}{V_i}\\\\\delta V=\dfrac{1.96-2}{2}\\\\\delta V=0.02\)
So, the volume strain on the box is 0.02.
