The most appropriate answers are ...
high frequency sound has shorter wavelength !
a higher pitch than low frequency...!!
so , wavelength and pitch !!
Answer:
Equations for speed, velocity and acceleration depend on change of position over time. Average speed uses the equation "speed equals distance traveled (d) divided by travel time (t)," or average speed = d ÷ t. Average velocity equals speed in a direction
We also learned that speed is a scalar quantity, which is one that requires only a magnitude, while velocity is a vector quantity, which is one that requires a magnitude (also mph) and a direction. The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

Answer:
Percentage change in tension is 3.8%
Explanation:
We have given initially frequency = 440 Hz
Let tension in the string at this frequency is
Now second frequency is
Frequency in string is given by
From the relation we can say that
Percentage change in tension is equal to
%
So percentage change in tension is 3.8%
