this is one question with 3 parts
D. From a location 4.0 m away, you listen to a jackhammer breaking concrete. 1. How far away would you have to stand in order to reduce the sound intensity by a factor of 8 (12 = 11/8)? Show your calculation. 2. If the intensity of the sound has decreased by a factor...

4.82 A rectifier" circuit is made by connecting two square-law devices in parallel, as shown in Fig. P4.82. One device has parameters A)-0.5 mA/V2 and VTR ov, the other A2 1.0 mA/V2 and VTR 0V. A sym metric input consisting of a :5-V square wave is applied to the rectifier, and a resistor RL 1 kS2 is connected as the...

Waves, as well as objects, spread out while going through a narrow opening. a. True b. False c. Not enough information You pass a sound and a light wave through identical single slits whose size is half the wavelength of the light wave. After leaving the slit, the wavefronts of the sound and light waves are respectively: a. Planar and...

Inchy, an inchworm, is inching along a cotton clothesline. The 5 meter long clothesline has a mass of 0.2 kilograms, and is pulled tight under 100 N of tension. Vivian is hanging up her swimsuit 0 meters from one end when she sees Inchy 2.54 cm (one inch) from the opposite end. She plucks the clothesline sending a terrifying 3...
