Activity 3: Direction: Answer the following question. Show your solution and round-off your answer to the nearest thousandths (3 decimal place) 1. A concert was held on an open field. You and your friends were there at the time and were 20 m away from the speaker. (a)How much intensity of sound would you here if the speaker has a 15,000 W of power and is used at its full capacity? (b)According to National Institute on Deafness and Other Communication Disorders, long or repeated exposure to sound at or above 85 decibels can cause hearing loss. With this information, at least how much more should you and you friend move from your current position to prevent any hearing damages?

How to synthesize non-pitched sounds? How pitched is a sound in general?

The intensity of the sound wave is 100 Wim2 at a distance of 3m What is the intensity of the sound wave at a distance of Gm? What is the intensity at 9m? Answers 25 Wim2 11.1 Wim2 If a bright flashlight has a light intensity of 15.0 candela at a distance 1.00 m from the lens, what is the intensity of the flashlight 100.0 m from the lens? Answer I, = 0.0015 candela. The intensity of the radio signal is 0.120 Wim at a distance of 16.0 m from a transmitter. What is the intensity of the signal at a distance of 4.00 m from the same transmitter? Answer 1.92 W/m'.

Direction: Show the complete solution for the following problems. Use a clean sheet of paper in answering. 1. The hearing range of a normal human ear is from 20 to 20000 Hz. If the speed of the sound in air is 340 m/s, what are the shortest and the longest wavelengths that the human ear can hear? 2. If the speed of wave in passing from medium A to medium B doubles while keeping the frequency constant, what happens to the wavelength? 3. Suppose that two-point charges, each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them.

Help.

What is sound? What features of a sound wave and what aspects of sound do they correspond best to (amplitude vs frequency).

Give atleast the 3 uses of how sound wave is used in technologies in details. (Provide a drawing on the space provided below and explain the 3 technology seperately thoroughly on how these technologies work. Label your drawings to help with your explanation)

When you work through these problems, show your work for full credit. Step 1: Write down the equation needed to solve for velocity.   Velocity = wavelength x frequency Step 2: Place the known measurements into the equation. Step 3: Solve the equation. Carefully put the numbers into your calculator. Recheck your answers! It is very easy to hit the wrong button on your calculator. Remember to use correct SI units. The sound wave produced by striking the middle C key on a piano has a frequency of 440 Hz. The sound is traveling at 282 m/s. What is the wavelength?
