Amphibians wouldn't be able to live in polluted water, and would just start to randomly die for no reason. That is a really good sign the water could possibly be polluted.

A 5 Mhz ultrasound beam in soft tissue reflects off an object 5 cm deep. The time required to receive the echo at the transducer
miss Akunina [59]

Answer:

The time required to receive the echo at the transducer is t=3.34\times 10^{-10}\ s

Explanation:

Frequency of ultrasonic beam, f = 5 MHz

It reflects off an object 5 cm deep.

We need to find the time required to receive the echo at the transducer. The ultrasonic wave is an electromagnetic wave. it moves with a speed of light. Let t is the time taken by the wave to go once.

So,

t=\dfrac{d}{c}

t=\dfrac{0.05\ m}{3\times 10^8\ m/s}

t=1.67\times 10^{-10}\ s

Time to receive the echo at the transducer gets doubled. So,

t=3.34\times 10^{-10}\ s

Hence, this is the required solution.
