Frequency of the wave is 2 per second
Explanation:
- Frequency is the number of times waves pass at a particular point of time. Here, given time period = 3 s and number of waves that pass in 3 seconds = 6. Find the frequency of the wave per second.
- Frequency is given by the formula
f = 1/T, where f is the frequency and T is the time period
- For 3 seconds, frequency is 6
3 seconds ⇒ 6 waves
⇒ 1 second = 6/3 = 2 waves per second
Answer:
Remember that the nucleus of an athom is neutral, which means protons, neutrons and electrons have the same and opposite charge so that the net electircal field is zero. In that case, we say the nucleus is estable.
Now, to mantain the equilibrium of the given element, we need an electrical field equal in magintude +2e with opposite direction, that will balance it.
