Answer: 8 years
Explanation:
According to Kepler’s Third Law of Planetary motion <em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”:</em>
<em />
(1)
In other words: this law states a relation between the orbital period
of a body (moon, planet, satellite, comet, asteroid) orbiting a greater body in space (the Sun, for example) with the size
of its orbit.
However, if
is measured in years (Earth years), and
is measured in astronomical units (equivalent to the distance between the Sun and the Earth:
), equation (1) becomes:
(2)
This means that now both sides of the equation are equal.
Knowing
and isolating
from (2):
(3)
(4)
Finally:
This is the period of the asteroid
The return of a wave back to its original medium is called an reflection
If you're talking about S.I. Unit then it must be "meter" (nothing else). Meter is the only S.I. Unit of length and it also uses in measuring the length of an automobile 'cause it varies from few meters to several thousand meters.
In short, Your Correct answer would be "meter" (m)
Hope this helps!
The gravitational force between two masses is given by:

where
G is the gravitational constant
m1 and m2 are the two masses
r is the separation between the two masses
We see that the force is proportional to the inverse of the square of the distance:

therefore, if the distance is tripled:
r'=3r
The force decreases by a factor 1/9:

Since the original force was 36 N, the new force will be
When a substance boils the molecules within the substance move faster and farther apart, meaning (depending on the current matter state of the substance) molecules will go into more liquid and gaseous states
solid----> liquid ----> gas
In the case of something boiling the substance goes from liquid to gas due to the increased molecular activity because to heat...
