The orbits of all the planets in the solar system are slightly elliptical with the exception of .

There is no exception to this. all planets have some eccentricity. it is physically impossible to have an orbit without any eccentricity. However, venus's orbit has the lowest (0.007) eccentricity (closest to circular) so that could be your answer.

Mercury's orbit's eccentricity 0.2

Venus's orbit's eccentricity 0.007 (this is the lowest so it may be your answer)

Earth's orbit's eccentricity 0.0167

Mars's orbit's eccentricity 0.0934

Jupiter's orbit's eccentricity 0.0489

Saturn's orbit's eccentricity 0.0565

Neptune's orbit's eccentricity 0.009

Uranus's (yur,in,iss) orbit's eccentricity 0.0457

Pluto's (not really a planet) orbit's eccentricity 0.2444 (very high)

hope it helped.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

answer: a. same unit
