Answer:
Thomson
Explanation:
Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model tried to explain two properties of atoms then known: that electrons are negatively-charged particles and that atoms have no net electric charge.
Answer: a) 5 x 10^5 kg/s b) 444 MW
Explanation:
Kinetic energy per unit mass Ke is
Ke = V^2 / 2
Ke = 3^2 / 2 = 4.5 J/kg = 0.0045 kJ/kg
Now potential energy per unit mass Pe is
Pe = g x z = 9.8 x 90 = 882.9 J/kg = 0.8829 kJ/kg
The total mechanical energy of the River per unit mass e = Ke + Pe = 0.0045 + 0.8829 = 0.88744 J/kg
M = P x V = 1000 x 500 = 5 x 10^5 kg/s
b) power generation potential of the entire river at the location Wmax = Emech = M x Emech = 500,000 x 0.88744 = 444,000kW = 444MW
Valence electrons is the correct answer
Answer:
Both of them.
Explanation:
By low or high spin complex we refer to all spins in the system (complex) aligned either up or down, which is normally simulated in Ising model. It means that all spins aligned, either up or down, like this:
∧ ∧∧ ∧∧ ∧∧ ∧
║║║║║║║║
(Those are arrows pointing up) are a stable configuration (lowest energy), as it actually occurs in ferromagnetic materials.
