That's the impression you get from the sound, that you call 'high' or 'low', determined by the FREQUENCY of the wave.
Answer:
the variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variables is the cause and the dependent variables is the effects. It's value depends on the changes in the independent variable.
Explanation:
I hope this small infor is helpful
The wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
Answer:
Part a)
H = 26.8 m
Part b)
error = 7.18 %
Explanation:
Part a)
As the stone is dropped from height H then time taken by it to hit the floor is given as
now the sound will come back to the observer in the time
so we will have
so we have
solve above equation for H
Part b)
If sound reflection part is ignored then in that case
so here percentage error in height calculation is given as
<em>Answer:</em>
<em>Right hand rule</em>
<em>Explanation:</em>
<em>The rule by which the direction of a rotational vector can be found: take your right hand, curl your fingers and stick your thumb straight up. If you let the curl of your fingers follow the path of the rotating particle or body, your thumb will point in the direction of the angular velocity of the body.</em>
