<h3><u>Answer;</u></h3>

<em>Away from the focus</em>

Seismic waves carry energy from an earthquake <em><u>away from the focus</u></em>, through earth's interior and across the surface.

<h3><u>Explanation</u>;</h3>

<em><u>When an earthquake occurs energy is produced and is transmitted or released in form of a seismic waves.</u></em> Seismic waves are types of waves which results from an earthquake,<em><u> they are vibrations that move through the earth carrying energy</u></em> that has been released when an earthquake occurs.
The <u><em>focus is the point at which a rock that is under stress breaks and triggers and earthquake</em></u>. Seismic waves carry the energy released during an earthquake<em><u> away from the focus</u></em> through the earth in all directions.

Two objects with masses m and 3m are connected by a compressed spring so that the energy stored in the spring is 375 joules. If

cluponka [151]

Answer:

281.25 J

Explanation:

We are told that the two objects with masses m and 3m.

Also that energy stored in the spring is 375 joules.

Now, initially the centre of mass of the system took place at rest, it means v1 = v and v2 = v/3

Thus, from principle of conservation of energy, we have;

½mv² + ½(3m)(v/3)² = 375J

(m + 3m/9)½v² = 375

(4/3)m × ½v² = 375

Multiply both sides by ¾ to get;

½mv² = 375 × ¾

½mv² = 281.25 J

Therefore, energy of lighter body is 281.25 J

Consider two children sitting on a merry-go-round, with one closer to the outer edge and one closer to the center. show answer N

dolphi86 [110]

Answer:

They both have the same angular speed.

Explanation:

The mathematical formula for angular speed is:

$w=\frac{2\pi}{T}$

where $w$ is angular speed, $2\pi$ is a constant, and $T$ is the period (the time it takes the marry-go-round to complete a lap).

What we can see from the formula is that, since the $2\pi$ does not change its value, the angular speed depends only on the period T.

In this case for both the children closer to the outher edge and for the children closer to the center, the time to complete a lap is the same, because the time does not depend on where they are sitting in the marry go round. This means that the period for both is the same.

Thus, since the period for both is the same, the angular speed given by

$w=\frac{2\pi}{T}$ will also be the same

The reason galaxies that are distant from our galaxy move away from our galaxy more rapidly than those that are near is:

Nataliya [291]

The reason galaxies that are distant from our galaxy move away from our galaxy more rapidly is more space expands between us and distant galaxies.

<h3>What is a galaxy?</h3>

A galaxy is a group of millions of stars and their systems that are grouped due to gravitational forces.

According to the Big Bang theory, galaxies are expanding and separate among them.

In conclusion, the reason galaxies that are distant from our galaxy move away from our galaxy more rapidly is more space expands between us and distant galaxies.
