Current Attempt in Progress Flying Circus of Physics Party hearing. As the number of people at a party increases, you must raise your voice for a listener to hear you against the background noise of the other partygoers. However, once you reach the level of yelling, the only way you can be heard is if you move closer to your listener, into the listener's "personal space." Model the situation by replacing you with an isotropic point source of fixed power Pand replacing your listener with a point that absorbs part of your sound waves. These points are initially separated by r;= 1.90 m. If the background noise increases by AB = 4.70 dB, the sound level at your listener must also increase. What separation r, is then required?

Assig Cengage Learning VHF, or very high frequency, refers to radio frequency electromagnetic waves in the range 30 to 300 MHz. In the U.S., television stations broadcast channels 2 through 13 in the VHF range betwe- 54.0 MHz and 216 MHz, with ranges 72.0 to 76.0 MHz and 88.0 to 174 MHz not utilized for TV broadcasting. Each channel has a frequency width of 6.00 MHz. The table below gives the lower and upper frequency of each channel.
