Answer:

A. friction is greatly reduced.

Explanation:

Maglev train runs on the principle of repulsion force due to magnetic field

here we know that magnetic field will apply force on the train which helps to levitate train in air

This is why it runs forward due to other component of magnetic force and hence it can run with high speed in air with least friction as there is no two surfaces in contact with each other

So here we can say that

Train run with very high speed due to least value of friction between two surfaces which moves relative to each other

so correct answer is

A. friction is greatly reduced.

If you run your boat aground what should you do first
padilas [110]
If you run your boat aground, the first thing you should do is to calmly assess the situation. In case you have passengers on your boat, you should have them don PFDs (personal flotation devices). Afterwards, you should turn off the engine, check if there is any damage, and generally see if everything is okay.
