Document Summary

Atmospheric pressure is the force of air molecules over the area of the earth s surface. Force = newton (1 nt = kg m s-2); work = nt m (force distance); frequency = hz (cycles s-1); Arms = 7. 07 v: a sine wave has a rms amplitude (arms) of 10 volts. Apeak =14. 14 v: an object exhibiting uniform circular motion has an angular velocity of 628. 318 radians s-1. = 2 f ; f = /2 ; = 628 radians s-1: a frequency of 4 hz corresponds to what angular velocity? f = 100 cycles s-1 or hz. = 8 radians s-1 (or = 25. 13 radians s-1) Paul a. faure: how many millimeters will a sound with a frequency of 1000 hz travel in air in 2 ms? cair = 340 m s-1 ; = c/f ; cair = 340 m s-1 ; = 340 m s-1 / 340 hz ;
