Wave on a string simulation

1) It takes more energy to move faster.
2)Fast frequency corresponds to high energy.
3) At frequency 27 and amplitude 50 it is 0.98Hz,
4) At frequency 100 and amplitude 50 it is 3.6Hz
5) At frequency 27 and amplitude 100 it is 0.98Hz
6) At frequency 27 and amplitude 50 it is 61cm
7) At frequency 100 and amplitude 50 it is 26.5cm
8) The higher the frequency the more energy it takes and the shorter the wavelength will be. The lower the frequency the less energy it takes and the longer the wavelength will be.

Describe 10 nm and mole of atoms

A single human hair has a diameter of about 50,000 to 100,000 nanometers. So 10 nanometers is 5 to 10 thousand times smaller then the size of a human hair.

1 mole of atom contains 6.022 x 10 to the 23 atoms. If that were a stack of pennys it would reach to the sun and back 500 million times.
A mole of atoms is the amount of atoms it takes to have the atomic mass of that atom in grams.
