Water is a valuable resource because it can be used for both human consumption and electricity generation. Which of the following choices is a poor way to conserve water?
A) Doing a full load of laundry in the mornin
B)Using the dishwasher only when it’s full.
C) Turning off the lights when you are not home
D) Taking a long shower to keep your brother from having any hot water.
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.
Answer:
I would say B makes the most sense here
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
help please
whats an example of kinetic energy
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.

Most of the sun's radiation passes through Earth's atmosphere and is absorbed by land and water. The diagram below shows some of the ways in which air is
What kind of energy transfer is shown by the movement of the air labeled B in the diagram?
Answer: B
Explanation:
In a chemical reaction, the bonds in the molecules
A.stay the same
B.change
C.vary
D.travel
Answer:
B. change
Explanation:
In a chemical reaction, the bonds in the molecules break apart and form new ones, thus b is the correct answer because they change.

Explanation:
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?
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.
