) So we are in a Universe with no center and no edge, but it is expanding... and it might be infinite. And it is all space and t

ime and mass and energy, but was born out of nothingness. What do you think about this? Does it seem sensible and natural or do you find it odd and confusing? Can you think of any better explanation for what we see? I would like your answer to be at least five (5) sentences long.

Answer:

Explanation:

A lot of physicist and many cosmologist believe by their research works on quantum fluctuation that it is possible for the universe to be created out of nothing. They believe and has almost proved that particle comes in and out of existence from empty space. This idea led them believe that big bang singularity also came out of nothing (hyperspace) by quantum fluctuation creating positive and negative energy of equal amount. Thus conserving  law of energy. In this scenario, positive energy is matter and negative energy is gravity so total energy of universe/big bang singularity is zero. Therefore, it is plausible for our universe to come out of nothing on its  own. But why universe came into existence it's own confirming  the idea of 'why there is something rather than nothing' as Lawrence Maxwell Krauss hypothesized could be correct.

an object is producing a sound that has a wavelength in air of 2.69m. If the speed of sound in air is 346m/s, what is the freque
Misha Larkins [42]

Answer:

129.74 Hz

Explanation:

Given:

Wave velocity ( v ) = 346 m / sec

wavelength ( λ ) = 2.69 m

We have to calculate Frequency ( f ) :

We know:

v = λ / t [ f = 1 / t ]

v = λ f

= > f = v / λ

Putting values here we get:

= > f = 346 / 2.69 Hz

= > f = 34600 / 269 Hz

= > f = 129.74 Hz

Hence, frequency of sound is 129.74 Hz.
