Decreases density because gases have less density than liquids
Answer:
1917723.40119 m/s
Explanation:
m = Mass of deuteron = 
k = Boltzmann constant = 
T = Temperature = 
RMS velocity is given by
The RMS velocity of the deutrons is 1917723.40119 m/s
I know this question is from 2017 but I am doing this for anyone else that is looking for a answer. The answer should be C.) Allowed psychology to be considered a science.
The area under the acceleration time graph represents change in velocity
The graph is plotted with acceleration on the vertical axis and time on the horizontal axis. The area under such graph represents change in velocity
The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
- atoms are spheres of positive charge
- electrons are dotted around inside
