The answer for the following problem is mentioned below.
- <u><em>Therefore the time period is 0.02 seconds.</em></u>
Explanation:
Frequency:
The number of waves that pass a fixed place in a given amount of time. (or)
The number of waves that pas by per second.
The SI unit of the frequency is Hertz(Hz).
Time period:
The time taken for one complete cycle of vibration to pass a given point.
The SI unit of time period is seconds. (s)
Given:
Frequency (f) = 39.5 Hz
To calculate:
Time period (T)
We know;
According to the problem;
From the problem;
<u>f = </u>
<u></u>
Where;
f represents the frequency
T represents the time period
f = 
f = 0.02 seconds
<u><em>Therefore the time period is 0.02 seconds.</em></u>
Answer:29 electrons
Explanation: If you look on a periodic table, the atomic number is the amount of electrons it has.
Before positive psychology, the main focus was mostly pathology, that is, studying various psychological issues and sometimes finding ways to treat them, or sometimes not and just studying them for the sake of studying them and noting their occurrence.
