The longest pipe on a certain organ is 5.34 m. (a) what is the frequency f3 (at 0.00°c) if the pipe is closed at one end?

-Dominant- [34]

For a pipe open at both ends, fund frequency (Fo) given byFo = v /2L

v = velocity of sound = 340 m/s (at about 20ºC)

Fo = 340/2*5.34 = 31.8 Hz

While for the one closed at one end and open at the other end...

For a pipe open at one end, fund frequency (Fo) given byFo = v/4L

Fo = 340/4*5.34= 15.9 Hz

A fan blade, initially at rest, rotates with a constant acceleration of 0.029 rad/s2. What is the time interval required for it

LenKa [72]

Answer:

The time interval is $t = 21.30 \ s$

Explanation:

From the question we are told that

The constant acceleration is $\alpha = 0.029 \ rad / s^2$

The displacement is $\theta = 6.58 \ rad$

According to the second equation of motion we have that

$\theta = w_i* t + \frac{1}{2} * \alpha t^2$

given that the blade started from rest

$w_i$ which is the initial angular velocity is 0

So

$\theta = 0 + \frac{1}{2} * \alpha t^2$

=> $t = \sqrt{ \frac{2 * \theta }{\alpha } }$

substituting values

=> $t = \sqrt{ \frac{2 * 6.58 }{0.029 } }$

=> $t = 21.30 \ s$

Which level of organisms get the most energy out of the food they make or consume?

boyakko [2]

Higher-level consumers get the most energy from food they eat.
An example is a lion eating a zebra. The zebra has more energy than a handful of grass, which has almost none to offer.

Halfway through her run when the music stopped playing, was there energy in Mila’s phone? Why or why not?

denpristay [2]

Yea. Sound energy. It was most likely I am pretty sure. If she was listening to it................hope this is right
