Professor Stefanovic is spinning a bucket of water by extending his arm and rotating his shoulder in class to show the effects o
anyanavicka [17]

Answer:

a ) 2.368 rad/s

b) 3.617 rad/s

Explanation:

the minimum angular velocity that Prof. Stefanovic needs to spin the bucket for the water not to fall out can be determined by applying force equation in a circular path

i.e

F_{inward } = F_G + F_T   ------ equation (1)

where;

F_{inward} = m *a_c

F_{inward} = m*r* \omega^2

Also

F_G = m*g

F_T = 0          since; that is the initial minimum angular velocity to keep the water in the bucket

Now; we can rewrite our equation as :

mr \omega^2= mg + 0\\\omega^2 = \frac{m*g}{m*r}\\\omega^2 = \frac{g}{r}\\\omega = \sqrt{\frac{g}{r} \ \  }     ------ equation \ \ \ {2}

So; Given that:

The rope that is attached to the bucket is lm long  and his arm is 75 cm long.

we have our radius r = 1 m +  75 cm

= ( 1 + 0.75 ) m

= 1.75 m

g = acceleration due to gravity = 9.81 m/s²

Replacing our values into equation (2) ; we have:

\omega = \sqrt{ \frac{9.81}{1.75}}\\\omega = 2.368 \  rad/s

b) if he detaches the rope and spins the bucket by holding it with his hand ; then the radius = 0.75 m

∴

\omega = \sqrt{ \frac{9.81}{0.75}}\\\omega = 3.617 \  rad/s

A formant is _________.
Stolb23 [73]

Answer:

Our final answer is option (c) that is :

A resonant mode of your vocal tract.

Explanation:

Lets understand pitch of a sound first:

Pitch: Is the rate of vibrations produced and also the degree of lowness and highness of a tone.

Pitch formant:

When we take air  inside our vocal tract it oscillates at different pitches depending upon the cast and capacity of the opening of the vocal tract.

Formant comes from the vocal tract and also at a resonance of our vocal tract.

So basically the vocal tract play a vital role for the formant.

Final answer is : A formant is a resonant mode of our vocal tract.

What are hot clouds of gaseous elements and compounds that act as nurseries for stars
Aleks04 [339]
Interstellar gas clouds are common in many galaxy, like the Orion nebulae which many young stars are being born. A typical nebula is many light years in diameter and contains enough material mass to make several thousand stars the size of our sun. The majority of the gas in nebulae consist of molecules of hydrogen and helium-but most nebulae also contain atoms of other elements. All known element in our periodic table is also being made inside this crucible of this immense hot gas. The source of the organic molecules is still a mystery. Irregularities in the density of the gas causes a net gravitational force that pull the gas molecules close together.
