If you are sitting 8.20 m from a
70.0 W speaker, what is the
sound level in dB?
(Treat the speaker as a point source.)
(Unit = dB)

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

find the sum of the two horizontal vectors and the sum of the two vertical vectors

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
