The best description of Ernest Rutherford's experiment is letter C. The positively charged particles were fired through a gold foil. Most of these particles went right through, while others bounced back. This experiment led to the discovery of the nucleus.
<u>Answer:</u>

h is planck's constant
c is the speed of light
λ is the wavelength of light
Wavelength
<em>Thus, the wavelength of light associated with the transition from n=1 to n=3 in the hydrogen atom is </em><u><em>103 nm.</em></u>

On four, in real life, she could put it in a strainer and put a bowl below the strainer. The liquid will fall through and into the bowl, but the solids will stay in the strainer. That may not be correct in terms of your reading because I don't know what the reading is.
