Answer:

1228.25

Explanation:

This is because the kinetic energy is when the body is in position so half of the speed or velocity with the mass equals the kinetic energy

Since the density of air decreases with an increase in temperature, but the bulk modulus B is nearly independent of temperature,

Usimov [2.4K]

To develop this problem it is necessary to apply the concept related to the speed of sound waves in fluids.

By definition we know that the speed would be given by

$v=\sqrt{\frac{\beta}{\rho}}$

$\beta =$ Bulk modulus

$\rho =$ Density of air

From the expression shown above we can realize that the speed of sound is <em>inversely proportional</em> to the fluid in which it is found, in this case the air. When the density increases, the speed of sound decreases and vice versa.

According to the statement then, if the density of the air decreases due to an increase in temperature, we can conclude that the speed of sound increases when the temperature increases. <u>They are directly proportional.</u>

In the image, not to scale, which phase of the moon would you observe from earth?

timofeeve [1]

Answer:

The "new" moon phase is being shown because the moon shown is directly between the sun and earth and is not visible from the earth because of the brightess of the sun.
