In the Bohr model of the hydrogen atom, an electron in the 2nd excited state moves at a speed of 5.48 105 m/s in a circular path of radius 2.12 10-10 m. What is the effective current associated with this orbiting electron

The current is

Explanation:

From the question we are told that

  The speed is  

   The radius is

Generally the period of the orbiting electron is mathematically represented as

=>        

=>    

Gnerally the effective current associated with this orbiting electron

Here e is the charge on an electron with value  

So

=>

0.19 m/s and 0.45 m/s

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
