Answer:
2.05 radians/s
Explanation:
This is a simple harmonic motion. The angular frequency of a loaded spring is given by

where
is the spring constant and
is the mass on the spring.
Using the known values,

They are too small are never in the same place. Electrons are constantly moving in random motion within the electron cloud, making them impossible to follow.
The Sun --> through 93 million miles of space, in about 8 minutes --> through the Earth's atmosphere --> through the glass window into your house --> through a little more air, inside the room --> through the glass fishtank --> through some water --> light hits the fish; all colors of light except yellow get absorbed by the fish; the yellow waves bounce off --> through the water again --> through the glass tank again, out into the room --> through some air again --> a little bit of the yellow light happens to go into your eye, and you see it. Most of it doesn't, though.
Atomic number represents the number of protons in an element (which is the number at the top of the box) and the mass number is the amount of protons and neutrons together (at the bottom). The number of protons is the same as the amount of electrons.
