Apiece of glass is immersed in a liquid. it proceeds to float on the liquid's surface. this shows that the density of the glass is ? the density of the liquid?

It shows that the density of the glass is less than the density of the liquid. The liquid must have a higher density for objects to float on it. This is because the force pushing the glass down on the liquid is less than the force the liquid is using to hold the glass up. 

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

Um i think answer is a
