An 11.8 eV photon is absorbed by an electron in an atom, causing the electron to be excited from level 1 to level 3. The electron then emits a 4.1 eV photon and shifts to level 2. What photon will be emitted when the electron moves back to level 1

Explanation:

energy absorbed by electron to get excited from level 1 to level 3

= 11.8 eV

energy released by electron when it  goes from level 3 to level 2 = 4.1 eV

energy released when electron goes from level 2 to level 1 = 11.8 - 4.1 = 7.7 eV

photon emitted = 7.7 eV photon .

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
