Rutherford's gold foil experiment proved that there was a small, dense, positively charged nucleus at the center, which contained most of the mass of the atom. Which contained electrons orbiting the nucleus.
The statement which best described the effect of color on energy absorption and reflection is this: LIGHT COLORS REFLECT MORE AND ABSORB LESS THAN DARK COLORS. Black color absorbs all incident radiations while white color reflects all incident radiations; all other colors fall in the midst of these two colors.
The helium in a glass model is a gas
Fluid Density= 1000000g/ 500 mL
10000g/5 mL, 2000 g/mL
Density water= 1 g/mL
It is denser than water so it should sink
