Sound cannot travel through a vacuum. Explain why.

Physics

Answer:

A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work on it.

A long string carries a wave; a 6.00-m segment of the string contains four complete wavelengths and has a mass of 180g. The stri
Viktor [21]

A long string carries the wave; a segment of the string measuring 6.00 meters in length and weighing 180 grams contains four full wavelengths. The string vibrates sinusoidally at a 50.0 Hz frequency with a 15.0 cm peak-to-valley displacement. The vertical distance between the farthest positive and negative positions is known as the "peak-to-valley" distance. The function that describes this wave traveling in the positive x direction is y=(7.50 \mathrm{~cm}) \sin \left(\frac{4 \pi}{3} \times-314 t+\phi\right).

\begin{aligned}& f=500 \mathrm{~Hz} \\&\mu=\frac{180 \times 10^{-3}}{6}=3 \times 10^{-2} K g / m \\&2 A=15 \times 10^{-2} m \\&A=7.5 \times 10^{-2} m \\&4 \lambda=6, \lambda=3 / 2 m \text {. and } v=f \lambda=75 m / \mathrm{sec} \\&\omega=2 \pi f=100 \pi \text { also } K=\frac{\omega}{v}=\frac{4 \pi}{3}\end{aligned}

If phase constant is $\phi$ then

$\therefore$ equation is $y=7.5 \times 10^{-2} \sin \left[100 \pi t-\frac{4 \pi}{3} x+\phi\right]$

∴ equation is y=(7.50 \mathrm{~cm}) \sin \left(\frac{4 \pi}{3} \times-314 t+\phi\right)

  • A wave is a disturbance that moves from one location to another, carrying energy but not always matter.
  • The square of the equation provides a probability density map of the locations where an electron has a specific statistical likelihood to be at any given moment in time. Wave functions have no direct physical meaning.

At 45 degrees s latitude, the angle of the noon sun is lowest and the length of daylight is shortest on:
Marat540 [252]

Answer;

- June 21

At 45 degrees latitude, the angle of the noon sun is lowest and the length of daylight is shortest on June 21.

Explanation;

-On June 21 you will note that the Northern Hemisphere is pitched toward the Sun. This means that the Sun's vertical ray is striking the Earth at the Tropic of Cancer (23.5 degrees N).

-Days tend to get longer in the northern hemisphere from December 21 to June 21, and then grow shorter from June 21 to December 21.  The June solstice is the summer solstice in the Northern Hemisphere and the winter solstice in the Southern Hemisphere. The date varies between June 20 and June 22, depending on the year, and the local time zone.

What Is the definition of the term gravitational potential energy​
OLga [1]

Answer:

Here are all the possible meanings and translations of the word gravitational energy. Gravitational energy is the potential energy associated with the gravitational field. This phrase is found frequently in scientific writings about quasars and other active galaxies. Quasars generate and emit their energy from a very small region.
