Answer:
Powerful electromagnets are fitted on top of guideways either ttract or repel the magents fitted on the bottom of train. The froce of attraction/repulsion rasies the train in hovering position.
Explanation:
Magentic fields exist between two opposite/like poles. The poles do not have to be touching each other. They can be separated by a distance in a medium that doesn' block magnetic field.
In magelv train the magnetic forces between two poles are used to operate the train. The two poles are separated by train body and air.
Your experiment should keep one thing constant and measure the other. So vary the temp and measure the pressure. You will get a set of data that relates pressure with temp.
<span>PV = nRT
So
P and T are directly proportional.
</span>These experiments are one of either Boyle-Mariottte's, Gay-Lussac'a or Charles' law.
<span>Metamorphic rocks will likely form at deep locations, where one type of rock will change into another. At choice (c), 8 km below the surface of the earth, rocks will undergo heat and pressure changes to where they will become other types of rock.</span>
Yes, I think that the universe is way to large for there not to be other life forms out there.
Answer:
When it goes up it gains PE and when it moves down PE is converted into KE
