Answer:
C
Explanation:
Im not sure but I did somthing simalier
Explanation:
(1). Formula to calculate the potential difference is as follows.
= 
= 
= 
= 
= 38.7 volts
Therefore, magnitude of the potential difference between the two spheres is 38.7 volts.
(2). Now, formula to calculate the energy stored in the capacitor is as follows.
E = 
= 
= 
Thus, the electric-field energy stored in the capacitor is
.
An atom is the building block of all matter. Electrons, protons and neutrons make up the atom. protons and neutrons make up the nucleus of the atom, and the electrons are on the electron shell.
Answer:
c. 7.7 eV
Explanation:
The computation of the photon emitted is shown below:
Given that
From level 1 to level 3, the energy absorbed by electrons is 11.8eV
And, when from level 3 to level3, the energy released by electron is 4.1eV
So, from level 2 to level 1, the energy released is
= 11.8 - 4.1
= 7.7
= 7.7eV
Hence, the third option is correct
The same is to be considered
And, the other options are wrong
