A football field is about 100 m long. If it takes a person 20 seconds to run its length, how fast were they running ?
1 answer:
Hi Alex, thanks for asking a question here on Brainly!
We can figure how the fast the person is running by dividing the minutes by the seconds.
=
=
The person was running 18 km/hr. ✅

The ground-state electron configurations of transition metal ions are diamagnetic [Kr]
. The ion is diamagnetic because there all electrons are paired.
- A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
- In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
- All materials experience the quantum mechanical phenomenon known as diamagnetism, which is the only source of magnetism in a material.
- The magnetic dipoles within paramagnetic and ferromagnetic materials exert an attracting force that outweighs the modest diamagnetic force.
- Diamagnetic materials have a magnetic permeability that is less than vacuum, or 0.
- Although superconductors behave as strong diamagnets, diamagnetism is often a modest effect that can only be observed by sophisticated laboratory equipment.
