this sh**
It is touching it, so there is no distance between them.
you measure the distance between the nuclei of 2 touching atoms then taking that distance and cutting it in half
what is the required distance beteen emergaency exit dorrs for industrial buildings
200 feet
Maintain a safe distance between vehicles. Never tailgate.
Zero - that is, when they are touching. The strength of the magnetic force is inversely proportional to the square of the distance between the magnet and the paper clip.
maintain distance between your eye and and eye piece of the microscope it helps
Understand that there is no relationship between the amount of steering required and the distance you are from the object
That would depend on where it's sited.
If the magnets are touching, then yes there is, if they are at a distance then the only friction they would have is from the air between them.
1. Energy is required to create a magnet, but no energy is required to maintain a magnet(magnetic field). 2. Like poles repel each other, and unlike poles attract each other. 3. The magnetic force between two poles is directly proportional to the pole strength and inversely proportional to the square of the distance between them.
