[填空题]
Two strings on a mus7(*pixdju5at 3 b5a rdic+nmh. kk9zlfho6.b w4al instrument are tuned to play at 392 Hz (G) and 440 Hz (A).z+ 69.k wnlb.h k4fhmo
(a) What are the frequencies of the first two overtones for each string? G : $f_2$=    Hz $f_3$=    Hz A : $f_2$=    Hz $f_3$=    Hz
(b) If the two strings have the same length and are under the same tension, what is the ratio of their masses ($m_{\mathrm{G}}/m_{\mathrm{A}}$)   
(c) If the strings instead have the same mass per unit length and are under the same tension, what is the ratio of their lengths($L_{\mathrm{G}}/L_{\mathrm{A}}$)   
(d) If their masses and lengths are the same, what must be the ratio of the tensions in the two strings?
