To determine the speed of the wave in part (a) and part (b) of the drawing, we can use the wave speed formula, which is given by:
v = √(F/T),
where:
- v is the wave speed,
- F is the tension acting on the string, and
- T is the linear density of the string.
In part (a) of the drawing:
- The tension acting on the string is provided by a 15.0-N block.
- The linear density of the string is 0.0483 kg/m.
Substituting the values into the formula, we have:
v = √(15.0 N / 0.0483 kg/m).
To calculate the wave speed, divide the tension by the linear density:
v = √(310.37 m^2/s^2).
Therefore, in part (a) of the drawing, the speed of the wave is approximately 17.6 m/s.
In part (b) of the drawing, the same calculations can be applied to find the wave speed using the given tension and linear density.
Note: Ensure that all units are consistent throughout the calculations.
