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.

The purpose of California’s law on seat belt use include:

  • To protect children from getting injured in a car accident.
  • To reduce the number of infant fatalities due to car accidents.
  • To enforce the need to exercise safety when driving with children.

<h3>What is Seat belt?</h3>

This is referred to as a safety device which protects the driver and passengers from harmful movement during a collision of two more vehicles.

When collision occurs, the force acts on the passengers and results in the movement of parts of the body which is why was enforced to ensure safety. It prevents the body from hitting other parts of the vehicle such as windscreen etc which could be fatal.

This is why it must be practiced at all time and helps reduce the number of fatalities encountered during an accident or sudden stop in vehicles.
