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?

Current Attempt in Progress Two astronauts are 2.50 m apart in their spaceship. One speaks to the other. The conversation is transmitted to earth via electromagnetic waves. The time it takes for sound waves to travel at 343 m/s through the air between the astronauts equals the time it takes for the electromagnetic waves to travel to the earth. How far away from the earth is the spaceship? Number Units
