Q3: A 1.0 W point source emits sound waves isotopically. Assuming that the energy of the waves is conserved, find the intensity (a) 1.0 m from the source and (b) 2.5 m from the source. (Hint: the area of the sphere is 4ar')
A speaker-driver supplies W watts of power to waves traveling on an elastic sheet. As these waves travel outward in circular ripples, the intensity of the wave at a radius of 10 cm. is 5 W/cm. The power emitted by the source is
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 1.46 cm, and it produces a sound intensity of 6.53 × 103 W/m2. How much time is required for the transducer to emit 3910 J of sound energy?

Urgent please! A firecracker produces a power of 2.5x10-3 mw.a. What is the intensity of a firecracker at a distance of 3.00 m from thefirecracker?b. How many firecrackers would be required to produce a sound level of 120db at a distance of 5.00 m from the firecrackers?
You hear a song from your playlist you haven't heard in a while and it warrants you to commence singing. As you are sing, the power of the compression wave you create is approximately 297.02 nW (note, nW is nano-Watts). What is the intensity of this sound as measured by your roommate who is standing 6.04m from you? Please give your answer in units of nW/m2. This unit is not a common one. Usually, the unit would simply be Watts per square-meter (which would be your answer divided by a million!). This goes to show you that are ears are amazingly sensitive to very tiny sound intensities. Note: Intensity was a topic covered in section 11.1, and I will provide the formula: I = P / A where P is the power in units of Watts, and A is the surface area of a sphere of radius "L" (in this problem).

You hear a song from your playlist you haven't heard in a while and it warrants you to commence singing. As you are sing, the power of the compression wave you create is approximately 579.05 nW (note, nW is nano-Watts). What is the intensity of this sound as measured by your roommate who is standing 9.89m from you? Please give your answer in units of nW/m2. This unit is not a common one. Usually, the unit would simply be Watts per square-meter (which would be your answer divided by a million!). This goes to show you that are ears are amazingly sensitive to very tiny sound intensities. Note: Intensity was a topic covered in section 11.1, and I will provide the formula: ?=?/?I=P/A where ?P is the power in units of Watts, and ?A is the surface area of a sphere of radius "L" (in this problem).
