Answer:
Potential
Explanation:
This is because it has not yet fallen, and it has the potential to fall and turn into kinetic energy. When it starts falling, it will be kinetic.
Answer:
Kinetic energy, E = 9.1 eV
Explanation:
It is given that,
At the first excited state of a particular atom is 5.7 eV above the ground state. The kinetic energy of the atom after the collision is 3.4 eV.
We need to find the kinetic energy of the electron just before the collision. The conservation of momentum will be followed here. The energy gets transferred from moving electrons to these atoms is 5.7.
Let E is the kinetic energy of the electron just before the collision. It is equal to :
E = 5.7 eV + 3.4 eV
E = 9.1 eV
So, the kinetic energy of the electron just before the collision is 9.1 eV. Hence, this is the required solution.
Explanation:
in my opinion I'd say it's gravity because it's making the book stay in it's one and only position pulling the book at the center of the desk
