Which statement is true about every planetary orbit in our solar system?
The sun is at the focus of the orbit.
The sun is at the center of the orbit.
The planet is at the focus of the orbit.
The planet is at the center of the orbit.
Why does an astronaut weigh more on the Jupiter than on Earth?
The astronaut has less mass on Jupiter.
The astronaut is farther from Earth's center on Jupiter.
Jupiter has greater mass than Earth, and therefore, greater gravitational field strength.
Jupiter is made from metals that have a much stronger magnetic pull than the metals on Earth.
What is the "orbital plane" of our solar system?
the imaginary plane on which a moon orbits a planet
the imaginary plane on which a planet’s orbit and the sun exist
What is the primary cause of ocean tides on Earth?
the fluctuations in the gravitational attraction between the Sun and the Earth
the differences in the gravitational force of the Moon at different points on Earth
the fluctuations in the gravitational attraction between the Sun and the Moon
the differences in Earth’s gravitational field strength at different points on Earth’s surface
Which orbit has a lower eccentricity?

An object is orbiting at a distance of 8,000 km from the center of a planet. The gravitational force between the object and the planet is 5N. What would the gravitational force be if the object were orbiting at a distance of 4,000 km?

20 N
50 N
