Two 350.0-W speakers, A and B, are separated by a distance D = 3.41m. The speakers emit in-phase sound waves at a frequency f =11800.0 Hz. Point P1 is located at x1= 4.51 m and y1 = 0 m; pointP2 is located at x2 = 4.51 m and y2 = –?y.
a) Neglecting speaker B, what is the intensity, IA1 (in W/m2), ofthe sound at point P1 due to speaker A? Assume that the sound fromthe speaker is emitted uniformly in all directions.
b) What is this intensity in terms of decibels (sound level,ßA1)?
c) When both speakers are turned on, there is a maximum in theircombined intensities at P1. As one moves toward P2, this intensityreaches a single minimum and then becomes maximized again at P2.How far is P2 from P1, that is, what is ?y? You may assume that L>> y and that D >> y, which will allow you to simplifythe algebra by using (a±b)1/2 ˜ a1/2 ± 0.5b/a1/2 when a >> b.

7.Someone is walking outside when the temperature of the air is -10°C. The metabolic rate of walking is 140 Cal/m2hr, and the usual muscle efficiency (20%) applies. They are completely covered by clothing with a coefficient of thermal conductivity of 0.36 Cal-cm/m2 hr °C. Their total surface area is 1.7 m2, and this area can be used as the area through which heat is being conducted away from the body. Their skin temperature is the same as the inside surface of the clothing, 35°C. The temperature of the outside of the clothing is -10°C. It is dark outside. Their mass is 75 kg. Ignore heat lost to breathing. How thick does the down have to be to maintain a constant internal body temperature of 37°C?
