Item 2 Which best explains why a wood-burning fireplace represents an open system? because they can be used for cooking because they are not all made of brick because the ashes have to be swept away because a fire requires oxygen from the atmosphere to burn

Answers

Answer 1

Answer:

Because a fire requires oxygen from the atmosphere to burn.

Explanation:

An open system is when the fire needs the air to burn and also allow the smoke to escape or be released without the need to be "guided" or drive along a made path such as a chimney or through a stack. This process ensures that no smoke is retained or confined in a closed space.

Burning of wood involves a great deal of smoke being released by the burnt wood. So, for the smoke to be released freely, the act of burning in an open space facilitates easier means of dispersing the smoke and not be harmful to the persons/ living things nearby. If wood burning is done in a closed space, it will only suffocate the ones inside the room, making it difficult for fresh air to facilitate easy burning and will require a chimney for the smoke to be released.

Thus, a wood-burning fireplace represents an open system as fire requires oxygen from the atmosphere to burn and also disperse the smoke easily without the need for a chimney or a stack.

Answers

Answer:

This would be a plea bargain.

Explanation:

The given arrangement would be a plea bargain, in the case if a person charged the defendant with attempted murder.

What is the plea bargain?

In criminal court proceedings, a plea deal is an arrangement whereby the prosecution makes a concession to the defendant in exchange for a guilty or no contest plea.

The most obvious advantage is the time and money savings for the parties, the court, and the public. Because the person receives a shorter punishment for admitting to a lesser offence, the defendant may frequently benefit from the plea negotiation process.

In most cases, finding a settlement outside of court is the primary goal of informal negotiations between the prosecutor and the defence attorney during the plea bargaining process.

Therefore, If the defendant were accused of trying to kill someone, the given arrangement would be a plea bargain.

federalism is more democratic and inclusive than unitary system of government.justify the statement with four reason

Answers

Explanation:

Federalism is an important concept of decentralization of power of state. The federal system is more democratic and participatory because of the following reasons:

In federalism the power of the state is decentralized to the federation , provinces and local levels so that the government can rule with the maximum participation of citizens.

Federalism is considered as more inclusive political system which ensures the equal opportunities and participation of all caste, class , gender and regions.

Federalism is based on the principal of cooperation , coexistence and collaboration which makes the federal system more democratic and transparent.

Federalism is a combine of federal , provincial , and local level governments which has formed through the elected representatives of people so that federalism can ensure the values of democracy.

Hope I helped!

Best regards!!

The main difference between federalism and unitarianism lies in the decentralization or not of the government structures of a given country in sub-national entities such as states or provinces. Now, this does not necessarily have any kind of link with democracy and the inclusion of citizens, due to the following reasons:

In both federalism and unitarianism, democracy is the form through which the rulers of the nation are elected. That is, the form of national organization does not determine the existence or not of a democracy. The inclusion of citizens within the government can take place in a federation or in a unitary government, since it does not necessarily imply a greater or lesser presence in the lives and needs of citizens. In turn, authoritarian governments can be decentralized, so that tyrants can control their territories through their subordinates, which means that democracy is not necessarily stronger in federal systems. Finally, democracy and inclusion are evident when social welfare is also evident. Therefore, if the government is structured in a federal or unitary way, it will not matter if the results are correct.

Answers

Answer:

c. both sequential and frustration mechanisms can promote responding during extinction.

Explanation:

Both sequential and frustration theories explain why there is increased resistance to extinction even when there should be extinction. The sequential theory explains that the subject's response increases when zero reward is followed by a reward intermittently so that the subject's memory of nonreward and reward trials boost response. In the same vein the frustration theory explains that a subject's response is increased with the partial reinforcement extinction effect whereby the subject is unable to notice when extinction begins(the discrimination hypothesis) and therefore keeps anticipating reward
