Question

Deep ultrasonic heating is used to promote healing of torn tendons. It is produced by applying ultrasonic sound over the affected area of the body. The sound transducer (generator) is circular with a radius of 1.40 cm, and it produces a sound intensity of 7.19 × 103 W/m2. How much time is required for the transducer to emit 3150 J of sound energy?

Answer 1

To find the time required for the transducer to emit a certain amount of sound energy, we use the formula: energy = power x time. Plugging in the given values, we can calculate the time required.

Step-by-step explanation:

To find the time required for the transducer to emit a certain amount of sound energy, we need to use the formula:

Energy = Power x Time

Given that the sound intensity is 7.19 × 10^3 W/m² and the required sound energy is 3150 J, we can rearrange the formula to solve for time:

Time = Energy / Power

Plugging in the values, we get:

Time = 3150 J / 7.19 × 10^3 W/m²

Calculating this gives us the time required for the transducer to emit 3150 J of sound energy.
