Answer: (b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at precise center of the ellipse. Minor axis is the same as other ellipses.
Explanation:
According to the first Kepler Law of Planetary motion, the orbit of a planet around the Sun, is in the form of an ellipse <u>with the Sun at one of the two foci of that ellipse</u>. This is also valid for any mass orbiting another mass greater than the first one in the space.
In this context, the ellipse is a conic, whose eccentricity is between 0 and 1. So, when its value is 0 we are talking about a circular orbit and when it is 1, a parabolic orbit.
That is, the nearer to the value of 1 (without reaching 1) the eccentricity of the orbit is, the more elliptical it will be.
In this sense, the only option that is incorrect is:
(b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others <u>with the Sun at precise center of the ellipse</u>. Minor axis is the same as other ellipses.
This statement contradicts Kepler's first law, because the Sun is <u>at one of the two foci of that ellipse</u>. The only way in which the Sun can be at the very center of the orbit is when we talk about a circular orbit. Since a circumference is a especial case of an elipse with eccentricity zero and we get only the center instead of the two foci.
Both Io nad Triton are moons that orbit around planets. Io<span> is the fifth moon out from </span>Jupiter, while Triton is the largest natural satellite of the planet Neptune.It <span>is similar in size to Earth’s moon and was discovered in 1846 .
</span><span>The similarities between Io and Triton</span> lays in the active volcanic like activities.
The correct matches are as follows:
<span>1. It contains large amounts of frozen water
</span><span>C. Europa
</span><span>
2. The temperature of its atmosphere is increased by high levels of carbon dioxide
</span><span>B. Venus
</span><span>
3. It doesn't have enough gravity to have an atmosphere
</span><span>A. Earth's moon
</span><span>
4. Astronomers believe there is a good chance it contains liquid water
</span>D. Mars
Hope this answers the question. Have a nice day.
Answer
B. Check her building’s foundation to ensure it is resistant to shaking caused by moving tectonic plates
Explanation
In the efforts of preventing damage to the house, Emily should first evaluate the elements outside the house that are potential hazards. These could be trees, electricity poles and power lines next/connected to the structure. This step should be followed by making any necessary repairs to the house. Emily can inspect the walls, roofing and foundation to detect any potential weakness. The third step can be adding support to crippled walls, anchoring sill plates to the foundation and installing windows with round corners.
