A piezoelectric quartz plate of thickness 5mm is vibrating is resonance. Calculate its fundamental frequency if for quartz.
`Y=8xx10^(10)N//m^(2)` and `rho=2.65xx10^(3)kg//m^(3)`.

Explanation

To calculate the fundamental frequency of a piezoelectric quartz plate of thickness 5 mm that is vibrating in resonance, we can follow these steps:

### Step 1: Understand the Formula for Fundamental Frequency
The fundamental frequency (ν₀) of a vibrating plate can be calculated using the formula:
\[ ν₀ = \frac{1}{2L} \sqrt{\frac{Y}{\rho}} \]
where:
