It holds A. Less water than when it is warmer.
The correct answer is “C” ultrasound. Hope this helps!
The period of the sound wave at the given frequency is determined as 0.00235 second.
<h3>
Period of the sound wave</h3>
The period of the sound wave at the given frequency is calculated as follows;
Period is reciprocal of frequency.
T = 1/f
T = 1/425
T = 0.00235 second
Thus, the period of the sound wave at the given frequency is determined as 0.00235 second.
