Question

can someone help me with this physics Lab Vibrating String Experiment I'm confused please and thank you

Vibrating String Experiment Objective To study the factors affecting the velocity of waves in a stretched string. Apparatus Linear transducer, function generator, string, meter stick, mass set, table clamp with pulley. Optional: strobe light.

I have This data for the four-time I did the Experience

Answer 1

mass perunit 3rd data' - 4hodep! Speedot have in astretched sting in an by the relation u=d I te Te tension mitte storing M= linearmasp density length somaos of 1.5m wire - 1-84gn = 1.84X103 1.5m Now Temg = 0.3kgx9-8= 300x173x98 N. v300x10389.8 x 15 1.94-X103 =48.96 mo exper Theortical value Now experment al value:- Node@ u=f*d for nodes v=f* ; f= 38:58H2. u=5787 mp.
