It was empty , dark , and cold
Answer : J. J. Thomson’s experiment disproved the theory that an atom is indivisible.
Explanation : Scientist J.J. Thomson did his experiment to prove the existence of electrons. He did the experiment using a cathode ray tube, in which a vacuum-sealed tube with a cathode and anode on one end was placed which created a beam of electrons that traveled towards the other end of the tube. This was the theory that proved that atoms consists of many subatomic particles namely electrons.
The nucleus is the center of the atom where the protons and neutrons can be found.
Answer:
0.0922 J/g°C
Explanation:
Use the formula Q=mc(delta)T. My teacher called it "M"cat to help my class remember it. Q-energy(560J) M-mass(130.6g) c(specific heat) is what you are solving for and delta T is the change in temperature(66.5-20.0). Put these values in the formula and solve for c.
