<span>The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune. The interesting thing is, in some other planetary systems discovered, the gas giants are actually quite close to the sun</span>
The greatest amount of kinetic energy is found with the train because it takes most energy to reach that velocity and also to slow down to a halt.
<u>Answer
</u>
He should make the arrow for “Path” curve downward.
<u>Explanation
</u>
The force of gravity is usually directly downward. So from the diagram, it is correctly labelled.
If the object was given a horizontal force, the direction of the inertial is also correct. Inertial is the force the resist the change of state of motion.
What Hector should change is the path followed by the object. It will be a curve not a straight line as it is drawn.
The correct answer is He should make the arrow for “Path” curve downward.
D. a train on a straight track
Answer:
The distance of the star is
meters
Explanation:
It is known that the speed of light has a value of
in vacuum. That is, it travels
in one second, according with the following equation:

Where v is the speed, x is the distance and t is the time.
(1)
Equation 1 can be used to determine the distance that the light travels in 1 year:
It is necessary to find how many seconds are in 1 year (365.25 days).
⇒ 
Therefore, in 1 year, light travels
meters.
<em>If the distance to a star is 3.6 light-years, what is this distance in meters? </em>
A simple conversion between units can be used to get the distance in meters
<em> ⇒ </em>
Hence, the distance of the star is
meters.
