Describe where the energy is coming from a hot air balloon

Answers

Answer 1

Explanation: When the air inside the balloon is heated, the molecules in the air begin to move around and spread out, and the air becomes less dense.

Answer 2

Answer:

Explanation:When the air inside the balloon is heated, the molecules in the air begin to move around and spread out, and the air becomes less dense. The surrounding, colder air falls beneath the hot air. This forces the warm air upward, which pushes the balloon up with it. The moving warm air creates a convection current.

true or false a second -degree burn may develop blisters

Answers

The answer would be true. During a second degree burn the top two layers of the skin are affected, which at times may result in painful blisters.

True. A second-degree burn can indeed develop blisters.

Second-degree burns are characterized by damage to both the outer layer of skin (epidermis) and the layer beneath it (dermis).

Blisters can form as a result of the burn, with the damaged skin producing fluid-filled pockets. Blisters in second-degree burns are often painful and can be a characteristic sign of this type of burn.

Third-degree burns are less painful than second-degree burns because third-degree burns result in nerve damage, which reduces feeling.

What does sharecropping tell you

Answers

Answer:

Sharecropping tells me about

Explanation:

Sharecropping is a type of farming in which families rent small plots of land from a landowner in return for a portion of their crop, to be given to the landowner at the end of each year. Different types of sharecropping have been practiced worldwide for centuries, but with the southern economy in disarray after the abolition of slavery and the devastation of the Civil War, sharecropping enabled landowners to reestablish a labor force, while giving poor whites and freed Black people a means of subsistence. About two-thirds of sharecroppers were white, and one-third were Black. The system severely restricted the economic mobility of the laborers, leading to conflicts during the Reconstruction era.

Technician a says that when more air is entering a spray booth than is removed it is considered to have negative pressure technician b say the negative air pressure draws more overspray through spray booth filters than positive air pressure Who’s right

Answers

Technician A is incorrect and Technician B is correct.

In a spray booth, when the amount of air entering the booth is greater than the amount of air being removed, it is considered to have positive pressure. Conversely, when the amount of air being removed is greater than the amount of air entering, it is considered to have negative pressure. Therefore, Technician A's statement is incorrect.

On the other hand, Technician B's statement is correct. Negative air pressure can draw more overspray through spray booth filters because it creates a vacuum effect that draws in the overspray and helps prevent it from escaping into the rest of the work area. This is why spray booths are designed to have a negative pressure differential to help control overspray and keep the work environment safe.
Both Technician A and Technician B are correct in their statements, but they are referring to different aspects of the spray booth operation.

Technician A is correct in stating that when more air is entering the spray booth than is being removed, it is considered to have negative pressure. Negative pressure means that the pressure inside the spray booth is lower than the pressure outside. This setup helps to contain the overspray and fumes within the booth, minimizing the risk of spreading them to the surrounding areas.

Technician B is also correct in stating that negative air pressure draws more overspray through the spray booth filters than positive air pressure. When the spray booth has negative pressure, it creates a suction effect. This suction draws the overspray particles towards the filters, improving their efficiency in capturing and removing the overspray from the air.

In summary, both technicians are correct in their statements. The negative pressure in the spray booth helps contain the overspray, and it also enhances the effectiveness of the booth's filters in capturing the overspray particles.

Read an excerpt from Benito Mussolini’s "The Doctrine of Fascism.” In the Fascist State, the individual is not suppressed, but rather multiplied, just as in a regiment a soldier is not weakened, but multiplied by the number of his comrades. The Fascist State organizes the nation, but it leaves sufficient scope for individuals; it has limited useless or harmful liberties and has preserved those that are essential. It cannot be the individual who decides in this matter, but only the State. What is the purpose of this excerpt? to explain the foreign policy of a fascist state to explain the role of citizens in a fascist state to describe the life of a soldier in a fascist state to describe the life of an official in a fascist state

Answer:

B.  to explain the role of citizens in a fascist state

Explanation:

Benito Mussolini was a Journalist, the leader of the National Fascist Party in Italy as well as the Prime Minister of Italy between 31 October 1922 to 25 July 1943. Benito Mussolini promoted Fascism, a political system that promoted a Corporatist economy where the society is structured according to corporate groups like agriculture, military, science, etc.

In the excerpt above Mussolini was emphasizing on the role of individuals or citizens in a Fascist state. He explained that a Fascist society does not suppress citizens, but rather organizes the nation and has few harmful liberties. In organizing the nation, individuals benefit as their essential liberties are preserved.

What is the most likely reason the rover won't travel in a straight line?

Answers

The rovers were designed to trek up to 100 meters (about 110 yards or 328 feet) across the martian surface each martian day, though they have gone much farther. While a complete martian day (called a sol) is about 24 hours and 40 minutes long (or 24 hours 37.5 minutes if you prefer), the Sun can only provide enough power for driving during a four-hour window around high noon. That means the rovers have to be able to move quickly and effectively.
Moving safely from rock to rock or location to location is a major challenge because of the communication time delay between Earth and Mars, which is about 20 minutes on average. Unlike a remote controlled car, the drivers of rovers on Mars cannot instantly see what is happening to a rover at any given moment and they cannot send quick commands to prevent the rover from running into a rock or falling off of a cliff.
During surface operations on Mars, each rover receives a new set of instructions at the beginning of each sol. Sent from the scientists and engineers on Earth, the command sequence tells the rover what targets to go to and what science experiments to perform on Mars. The rover is expected to move over a given distance, precisely position itself with respect to a target, and deploy its instruments to take close-up pictures and analyze the minerals or elements of rocks and soil.

Now, even if the car owner just replaced the oil, there could be several other things responsible for running out of oil.
