As solar wind approaches Earth, what happens to the charged electrons?
They are deflected as Earth’s magnetic field exerts force on them.
Which best describes how energy transferred from an electron in the solar wind compares with energy absorbed by an electron in the oxygen atom?

Which statement is accurate about how the aurora borealis is formed?
When the electrons fall to a lower energy state, they release energy as electromagnetic radiation, light.
How does the energy in the light of the aurora borealis compare to the energy as an excited electron returns to its original energy level?

During the formation of the aurora borealis, the electrons in an atom experience a change in energy levels. Which statement about this change is accurate?
First, the electron absorbs energy to move to a higher energy level.

Answer:
a joule is the unit of work
Explanation:
Answer:
Explanation:
electron attraction between electron and nucleus = centripetal force of the orbiting electron
In fact, Bohr model depicts the atom as a nucleus surrounded by electrons in circular orbit around it, similar to the planets around the Sun. The centripetal force that keeps the electrons in circular motion around the nucles is provided by the electrostatic force between the electrons and the nucleus.
The momentum is calculated by multiplying the mass and the velocity of the object.
momentum 1 : = (10 g)(4 m/s) = 40 g m/s
momentum 2: = (1000 kg)(0 m/s) = 0 kg m/s
Thus, the paper airplane has a greater momentum than the real airplane.
