A certain rope has a length of 8m and a mass of 1.6kg.It is fixed on one end and held fixed at the other with a tension of 50N.What is the speed of waves on this rope?
答
就不翻译了，计算你自己来吧
natural frequency：f = (1 / 2π) * √ (k / m)，其中 k=F/L=50N/8m
所以f = (1 / 2π) * √( (50N/8m )/ 1.6kg)
波长（人）=2*L=2*8m
速度： v=波长（人）*f
答
某绳长8米和质量1.6公斤的。固定一端，另一端给予50N与张力。绳子的波速是多少？
答
let me try.Since the question is in English,i think i would give 翻译后是这样,题目不会做,很久没碰过物理题了.
