Answer:
Christian
Explanation:
Given that
Force applied by Sean ,F₁=100 N
Force applied by Christian ,F₂=200 N
Lets take mass of the box = m kg
As we know that from second law of Newton's
F= m a
F=Force,m=mass ,a=acceleration
From the above we can say that acceleration a₂ is greater than a₁ is for the same mass of the box.
Therefore Christian will acceleration more for the box.
The frequency of the wave is 132 Hz
Explanation:
To calculate the speed of the wave, we can use the following formula:
where
d is the distance travelled by the wave
t is the time elapsed
For the sound wave in this problem, we have:
d = 660 m is the distance travelled
t = 2 s is the time interval considered
Substituting and solving for v, we find the speed of the sound wave:
Now we can calculate the frequency of the wave by using the wave equation:
where
v = 330 m/s is the speed of the wave
is the wavelength
f is the frequency
Solving for f, we find:
