False. according to marshall sahlins and class lecture, theft is a frequent problem in hunter and gatherer societies

According to Marshall Sahlins and anthropological studies, theft is generally not a frequent problem in hunter-gatherer societies. In these societies, resources are often shared and there is a strong emphasis on cooperation and reciprocity. The notion of private property is often less developed, and individuals rely on collective strategies for survival. Theft, as understood in modern societies, is not a common concern in the context of traditional hunter-gatherer communities.

Answer:

Explanation:

It appears that you are trying to solve a problem involving an insulated rigid tank containing saturated liquid water and water vapor. To determine the volume of the tank, you will need to know the mass of the liquid water and the mass of the water vapor. The mass of the liquid water can be calculated by multiplying the mass of the water and vapor mixture by the fraction of the mixture that is liquid water (1.4 kg * 0.25 = 0.35 kg). The mass of the water vapor can be calculated by subtracting the mass of the liquid water from the total mass of the mixture (1.4 kg - 0.35 kg = 1.05 kg).

To determine the final temperature of the tank, you will need to know the amount of heat added to the tank by the electric resistor and the specific heat capacity of the water and water vapor mixture. The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a certain amount. The specific heat capacity of water is 4.186 J/g°C, and the specific heat capacity of water vapor is 2.080 J/g°C.

To determine the electric power rating of the resistor, you will need to know the amount of heat added to the tank by the resistor and the time over which the heat was added. The power rating of the resistor is equal to the amount of heat added to the tank divided by the time over which the heat was added.

I hope this helps clarify the problem and provide some guidance on how to solve it. If you have any further questions or need additional help, please don't hesitate to ask.

Explanation:

To determine if the rings are pure silver, we can calculate the density of the rings and compare it to the density of pure silver. The density of a material is the mass of the material per unit volume.

First, we need to find the volume of one of the rings. Since the rings are cylindrical, we can use the formula for the volume of a cylinder to find the volume of each ring:

V = π * r^2 * h

Where V is the volume of the ring, π is approximately equal to 3.14, r is the radius of the ring, and h is the height of the ring. In this case, the height of the ring is equal to the thickness of the ring, which is equal to the change in the water level (8.45 mm) divided by the number of rings (10). The radius of the ring is equal to half the diameter of the graduated cylinder (2.5 cm / 2 = 1.25 cm), since the rings are placed in the cylinder side by side.

Plugging these values into the formula, we find that the volume of each ring is:

V = 3.14 * (1.25 cm)^2 * (8.45 mm / 10) = 0.00367 cm^3

Next, we can use the mass and volume of each ring to calculate the density of the rings:

density = mass / volume

Since the mass of each ring is 0.738g and the volume of each ring is 0.00367 cm^3, the density of the rings is:

density = 0.738 g / 0.00367 cm^3 = 201.09 g/cm^3

Finally, we can compare the density of the rings to the density of pure silver, which is 10.49 g/cm^3. Since the density of the rings is much higher than the density of pure silver, it is likely that the rings are not pure silver.

It is important to note that this calculation is only an approximate estimation of the purity of the rings. There may be other factors that affect the density of the rings, such as impurities or variations in the thickness of the rings. Additionally, the value of the density of pure silver used in this calculation may not be entirely accurate, as the density of a material can vary depending on factors such as temperature and pressure. A more precise determination of the purity of the rings would require further testing and analysis.

The source for mechanical motion supplied to a generator is referred to as the prime mover.

A generator is a device that converts mechanical energy into electrical energy. The mechanical energy is typically supplied by a prime mover, which is any device that can supply the necessary rotational force to turn the generator's rotor. The prime mover can be powered by various sources of energy, such as fossil fuels, nuclear energy, hydroelectric power, wind power, or solar power.

The type of prime mover used depends on the specific application and available resources. For example, in a traditional power plant, the prime mover is typically a steam turbine that is powered by burning fossil fuels or nuclear reactions. In a hydroelectric power plant, the prime mover is the water that drives the turbine. In a wind turbine, the prime mover is the kinetic energy of the wind that turns the rotor blades.

Regardless of the type of prime mover used, the goal is to provide the necessary mechanical motion to turn the generator's rotor. The rotor is surrounded by a stator, which contains a series of electromagnets that produce a magnetic field. As the rotor turns, it generates an electrical current in the stator coils through the process of electromagnetic induction. This current is then transmitted through power lines to homes, businesses, and other electrical loads.

In summary, the prime mover is the source of mechanical motion that is supplied to a generator to produce electrical energy. The type of prime mover used depends on the specific application and available resources.

Explanation: Dead Grass more flammable than wood and Green grass contains water.

The objective is to calculate the average power supplied or absorbed by each element in the circuit.

In the given circuit shown in Figure 11.35, to determine the average power supplied or absorbed by each element, we need to analyze the circuit and calculate the power for each element.

To calculate the power, we can use the formula P = VI, where P represents power, V represents voltage, and I represents current.

For each element in the circuit (such as resistors, capacitors, or inductors), we need to determine the voltage across the element and the current flowing through it. Once we have these values, we can calculate the power using the P = VI formula.

To find the average power, we need to consider the time-varying components, such as AC signals or time-varying currents or voltages. In this case, we might need to use techniques like calculus or complex analysis to calculate the average power over a complete cycle or a specified time period.

By applying the appropriate calculations and analysis techniques, we can determine the average power supplied or absorbed by each element in the given circuit shown in Figure 11.35.

The correct option for the implication of low variety is B) Flexibility needed. Variety refers to the number of different products, services, or activities that an organization offers. High variety means that a company offers a wide variety of products or services, while low variety means that a company provides a limited range of products or services.

One of the implications of low variety is that customers have limited options. They are restricted to purchasing only those goods and services that the company offers, which may not match their requirements or preferences. This may lead to losing customers to rivals who offer a greater variety of goods and services.

In the case of low variety, it is critical to have the required flexibility. Customers may ask for certain specific goods or services that are not provided by the company. To meet customer requirements, the company should be adaptable and able to rapidly respond to customer requests by expanding its product line. As a result, low variety necessitates the need for flexibility.

The other given options are not valid. Low unit cost is not related to low variety. Unit cost may be affected by economies of scale and other factors, but it is not directly related to variety. High complexity is not related to low variety as well. As the range of goods and services offered by the company increases, the complexity of the company's operations and management also increases. Matching customers' specific needs is partially correct because the company cannot match customer specific needs in low variety. In low variety, the company has a limited range of goods and services, so it is not possible to fulfill all the customers’ specific needs.

In a one-loop DC generator, the output voltage oscillates as the armature rotates in the magnetic field. The number of times the output voltage reaches its maximum value per second is equal to the number of times the loop cuts the magnetic field per second.

This frequency of voltage peak is called the frequency of the generator. It is given by:f = P × n / 60where f is the frequency, P is the number of poles, and n is the rotational speed of the generator in revolutions per minute.

Here, since the generator is rotated at 90 revolutions per second:f = P × n / 60 = P × 90 / 60 = 3/2 × PThe number of times the DC output voltage peaks per second is equal to the frequency of the generator. Therefore, the number of peaks per second is 3/2 times the number of poles. This is assuming that each rotation of the armature cuts the magnetic field twice (once for each side of the loop).

In this case, we can't determine the number of poles, so we cannot give an exact value for the number of peaks per second. However, if we assume a 2-pole generator, then the frequency of the generator would be: f = 3/2 × 2 = 3 peaks per revolution Therefore, for a 2-pole generator rotated at 90 revolutions per second, the DC output voltage would peak 270 times per second.
