Answer:
The answer to the question is
The correct weight of the former student = 116 lbf
Explanation:
To solve the question, we list out the known variables as follows
Capacity of the scale = 120 lbs
Capacity of the spring dynamometer = 20 lbs
Reading on the scale = 100lb
Reading on the spring dynamometer= 16 lb
at equilibrium, sum of forces = 0
Therefore weight of former student = reaction forces of the scale + the reaction force of the spring dynamometer = 100lb + 16 lb = 116 lb
The correct weight = 116lb weight or 52.62 kg
Converting to weight which is a force = mass * acceleration = 52.62 kg * 9.81 m/s² =
516.2 N = 116 lbf
The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. The last three trials involved the same procedure with a different rope tension.
