Answer:
I hope it is no too late
Explanation:
hmmm,
In a gas, for example, the molecules are traveling in random directions at a variety of speeds - some are fast and some are slow. ... If more energy is put into the system, the average speed of the molecules will increase and more thermal energy or heat will be produced.
<u>Explanation of the properties of electron spin:</u>
Electron spin:
Electron spin is a quantum characteristic of electrons. It is a mode of angular momentum. The magnitude of this angular momentum is perpetual. If the electron spins clockwise on its axis, it is described as spin-up; counterclockwise is spin-down.
- Electron spin has representative s
- The electron spin quantum number has representative ms.
Electron pair:
Electron pair is also known as lewis pair. Lewis pair consists of two electrons that fill the same molecular orbital but have opposing spins. Gilbert N. Lewis introduced the electron pair idea in a 1916 article.
Answer:She can increase the number of wire loops
Explanation: When the number of loops of wire ( usually around the iron ) increases, the strength of the electromagnet is increased.
According to the equation
B=μ₀ N I
Where
μ₀ = permeability of the core
N= Number of turns of the coil
I= Current flowing through the coil
From the equation above , we can see that The strength of an electromagnet depends the amount of current, no of turns of coil and the permeability core of coil. we can now say that Increasing the number of wire loops increases the strength of electromagnet.
Therefore, Lisa should increase the number of wire loops to increase the strength of the electromagnet
An atom in normal conditions refers when electrons are in the fundamental state. When you leave the atom, an electron absorbs energy from an external source and moves to a higher energy state.
Energy states or energy levels are called orbitals. The difference between the energy states in an atom is responsible for the emission of photons when an electron transition occurs between these two energy states.
Because the energy levels are discrete, the emitted photons also possess different energies.
