Aguitar string of length 30 cm and stretched under a tension of 78 n has a certain fundamental frequency. how long would a pipe, open at both ends, need to be to play the same fundamental frequency? a 15-cm long piece of the guitar string has a mass of 0.4 g. the speed of sound in air is 340 m/s.
a. 0.6 m.
b. 1.3 m.
c. 0.95 m.
d. 1.63 m.
e. 2.7 m.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

that would be because of both gravity and friction. so     c

it is a negative acceleration
