When breathing out, it pushes your diaphragm, the muscle below your lungs, up, which then causes the air to leave your lungs.

A projectile is launched horizontally from a height of 8.0 m. The projectile travels 6.5 m before hitting the ground.
lozanna [386]
You can find

1) time to hit the ground
2) initial velocity
3) speed when it hits the ground

Equations

Vx = Vxo

x = Vx * t

Vy = Vyo + gt

Vyo = 0

Vy = gt

y = yo - Vyo - gt^2 / 2

=> yo - y = gt^2 / 2

1) time to hit the ground

=> 8.0 = g t^2 / 2 => t^2 = 8.0m * 2 / 9.81 m/s^2 = 1.631 s^2

=> t = √1.631 s^2 = 1.28 s

2) initial velocity

Vxo = x / t = 6.5m / 1.28s = 5.08 m/s

3) speed when it  hits the ground

Vy = g*t = 9.81 m/s * 1.28s = 12.56 m/s

V^2 = Vy^2 + Vx^2 = (12.56 m/s)^2 + (5.08 m/s)^2 = 183.56 m^2 / s^2

=> V = √ (183.56 m^2 / s^2) = 13.55 m/s

Standing waves can be established within a cylindrical volume. However, it is not known if the volume is closed at both ends, op
Evgen [1.6K]

The frequencies are missing in the question. The three successive resonance frequencies within the volume are $f_1, f_2 \text{ and}\ f_3$.

Solution :

Let the volume be : v

The frequency for one end open and one end closed is given by :

So, $ f_n = \frac{(2n-1)v}{4L}$

Therefore,

$f_1 = \frac{v}{4L}$     ,     $f_2 = \frac{3v}{4L}$  ,     $f_3 = \frac{5v}{4L}$

So, $f_2 - 3f_1$  and  $f_3=\frac{5}{3}f_2$

Therefore, the ratio of   $\frac{f_3}{f_2}=\frac{5}{3}$    which is not a whole number.

Now the frequency for open volume and closed at both end

$f_n=\frac{nv}{4L}$

So,    $f_1=\frac{v}{4L}$   ,    $f_2 = 2f_1$ ,  $f_2=3f_1$

From above formulae we can see that  ratio of     is not a whole number that is a identification for the frequency of the volume at one end open and one end closed.

Also ratio of the consecutive frequency of the volume at open from both side and closed from both side is always a whole number.
