The results from the alpha particle scattering experiment led to the nuclear model.
Alpha particles were fired at a thin film of gold at a speed of 7% of the speed of light.
Determine the speed of the alpha particles.
Speed of light = 300 000 000 m/s

Rn in the right answer

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
