Physics Middle School

Students were creating graphs to illustrate the energy transformations that occur as a roller coaster moves along a track. The letters A-D on Graph 1 represent the position of a roller coaster as it moves along a track. The numbers 1-4 on Graph 2 were supposed to represent the energy of the roller coaster at positions A-D, but the students got their data mixed up. How should the bars in Graph 2 be ordered so that they match to the energy of the roller coaster as it moves from position A to B to C to D?

A- it's at the top and not moving so its all potential

B- Bottom so no potential, a little is lost to friction- a little thermal, it's moving so ther'es kinetic

C- in the middle hieght- some potential, lost more to friction so more thermal, not moving so no kinetic

D- bottom, so no potential. more energy lost to friction. still moving so some kinetic

When lights are turned off, the electrical circuit is _________, because _________. A. closed, because it stops electricity from flowing through the circuit.
B. open, which stops electricity from flowing completely through the circuit.
C. tangled, it is in a mess. D. broken, and does not let electricity flow through.

Answers

Answer:

I would say B makes the most sense here

It is A because everything does not make sense, b, when ever it’s answer for because, it does not work out, a closed it so it will stop it from flowing from the circuit, when it opens electricity flows through.

whats an example of kinetic energy

Answers

Answer:

A semi-truck travelling down the road has more kinetic energy than a car travelling at the same speed because the truck's mass is much more than the car's. A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.

Explanation:

Answer:

An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.

1. What could scientists learn by using the Law of Superposition?

2. How could this help people learn about earthquakes?

3. Is there any way to determine when the magma actually intruded with these clues only?

4. Could we use fossils to help determine the age of rocks (and thus the age of magma intrusions)?

5. What other methods could scientists use to date rocks?

Answers

Answer:

Explanation:

1.The Law of Superposition is a fundamental principle of geology that states that in a sequence of undisturbed layers of sedimentary rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. Scientists can use this law to determine the relative ages of rocks and the order in which they were deposited.

2.The Law of Superposition can help people learn about earthquakes because it provides a way to study the history of the Earth's crust and the geological forces that have shaped it over time. By studying the layers of rock and the patterns of deformation and displacement caused by past earthquakes, scientists can develop a better understanding of how earthquakes occur and how they may impact different areas in the future.

3.It may be possible to determine when the magma intruded by using additional clues, such as the presence of index fossils, the type of rocks present in the intrusion, and the relative ages of the surrounding rock layers. However, these clues would need to be interpreted in the context of other geological features and events in the area to arrive at a reliable estimate of the age of the intrusion.

4.Yes, fossils can be used to help determine the age of rocks, including magma intrusions. Certain types of fossils, known as index fossils, are useful for dating rocks because they are known to have existed only during a specific period of time. By identifying the index fossils in a rock layer, scientists can determine its approximate age.

5.Other methods that scientists can use to date rocks include radiometric dating, which involves measuring the decay of radioactive isotopes in minerals, and paleomagnetic dating, which uses the record of Earth's magnetic field preserved in rocks to determine their age. These methods can provide absolute ages for rocks and are often used in conjunction with the Law of Superposition to develop a more complete understanding of the history of the Earth's crust.

Which of the following statements is correct with regard to convection currents?

A. Convection currents in magma are caused by color differences.

B. Convection currents in magma drive the movement of tectonic plates.

C. Convection currents in magma are a result of how the magma is formed.

D. Convection currents in magma play a role in the movement of Earth's inner core.

Answers

Answer:

A.convection currents in magma are caused by color differences

The thermal conduction we find that the correct answer is:

     a) Convection currents in magma are caused by hot differences.

Thermal conduction occurs in three ways

Conduction.   When two material are in thermal contact with different temperatures, energy flows from the hottest material to the coldest, in this there is no material movement Radiation. Due to the absorption of radiant energy between bodies with different temperatures, it does not need physical contact, which is why it is the form of transmission in a vacuum. Convention. This occurs when a mass of liquid or gas is in contact with another colder mass and the material of the hotter mass moves upward in the cold mass, this form of heat transfer includes the movement of material, it is very important in liquid and gases.

 

The magna of volcanoes is a quantity of matter in a liquid or plastic state due to the thermal energy of the interior of the earth, when this mass reaches a colder and fissured area, it can rise towards the coldest part, breaking and deritating. the materials in its path.

Let's annotate the different statements

a) True. According to the explanation, the temperature of the magna causes it to rise due to convection currents.

b) False. The cracks are those that help the convection currents, in general the movement of the plates creates cracks

c) False. The movement of the plates is independent of the convection of the magna which is approximately vertical

d) False. The core of the planet is very deep (> 4000 km) and the magna currents reach about 14 to 20 km

In conclusion using the forms of thermal conduction we find that the correct answer is:

      a) Convection currents in magma are caused by hot differences.

Running is an example of potential or kinetic energy

Answers

When a person runs, their body must convert potential energy into kinetic energy. Potential energy is the energy stored within a system. Potential energy is used when the system uses kinetic energy to move in a horizontal direction. In the human body, potential energy is stored in the form of chemical energy.

Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!! Best answer I promise brainliest
