Consider an electron orbiting an atom.
How many nm/s is it covering if it moves around the atom 1000 times a second given that the distance from the electron to the atom is 1 nm. (Idk if this is really true, just a guess and example)
Electron in an atom's orbit.

The abswer is 2000π nm/s
Correct

This isn't hard physics
f=1000hz
ω=2πf ω=2000π rad/s
r=1nm
v=rω=2000π nm/s

True or you could also do it mathematically try working that one out it's even easier
