Explanation:
The given data is as follows.
Length (l) = 2.4 m
Frequency (f) = 567 Hz
Formula to calculate the speed of a transverse wave is as follows.
f =
Putting the gicven values into the above formula as follows.
f =
567 Hz =
v = 544.32 m/s
Thus, we can conclude that the speed (in m/s) of a transverse wave on this string is 544.32 m/s.
Answer:
Reduce its weight
Explanation:
For an object on a flat surface, the maximum force of friction experienced by the object is given by:
where
is the coefficient of friction
W is the weight of the object
As we can see from the formula, there are two ways of reducing the friction:
- Decreasing --> this coefficient depends on the material and on the roughness of the surface, so this can be changed by changing the properties of the surface
- Decreasing W, the weight --> this can be done by reducing the mass of the object
