The relationship between the speed, the frequency and the wavelength of a wave is given by:
where
f is the frequency
v is the speed of the wave
is its wavelength
for the pressure wave in this problem,
and v=1400 m/s, therefore its frequency is
Answer:
Geographers explore both the physical properties of Earth's surface and the human societies spread across it. They also examine how human culture interacts with the natural environment, and the way that locations and places can have an impact on people.
Answer:
The right approach is Option b (the force..................exert on you).
Explanation:
- Even before you fall on something like a soft object, users eventually slow to a halt. You are still giving away all the downward momentum, but progressively although with small powers, you are doing so.
- Although you can get injured by massive powers, this gradual displacement is a positive thing. And that is why you have a mattress you would like to settle on.
The other options given are not connected to the situation described. So, the solution here was the right one.
Explanation:
Below is an attachment containing the solution.
