Answer:
C
Explanation:
force equals mass time acceleration
Explanation:
It is known that formula for energy in the 1st exited state is as follows.
E =
And, for 1st exited state n = 2.
So, E =
= -3.4eV
It is given that energy added E' = 2.86 eV.
So, energy of the electron in nth state is as follows.
E" = E + E'
= -0.54 eV
we know E" =
-0.54 eV =
n' = 5
i.e., the electron exited from n = 1 to n = 5.
Thus, we can conclude that the quantum number n of the state into which the electron moves is from n = 1 to n = 5.
Magnetic field can be generated when electric charge is in motion.
In short, Your Answer would be Option C
Hope this helps!
Answer:
Centripetal acceleration = 83.77m/s²
Explanation:
<u>Given the following data;</u>
Radius, r = 0.13m
Velocity, v = 3.3m/s
To find centripetal acceleration;
Centripetal acceleration is given by the formula;
Substituting into the equation, we have;
<em>Centripetal acceleration = 83.77m/s²</em>
<em>Therefore, the centripetal acceleration of the edge of the disc is 83.77 m/s². </em>
