In the X-Men, super hero, comic book series, "Magneto" can move metal objects 50 feet away by simply willing it to happen with his mind. What kind of force is this?

In Newton's Law of Universal Gravity, the "G" constant changes solar system to solar system like "g" change from planet to planet.
True.
False.
4
Which force is NOT considered an inverse square law.
Magnetism between two permanent magnets.
The repulsion force between two electrons.
The attractive force between two planets.
Sound "volume" from the rock star's on stage and the audience.
A light's brightness.

If one of Mar's moons were moved 3 times farther away from Mars, then how does the Mar's gravitational pull compare? (The "new pull" in the answers is from a distance 3 times farther away.)
New pull = 4 times the old pull
New pull = 1/3 times the old pull
New pull = 1/9 time the old pull
New pull = 1/6 the old pull
New pull = 9 times the old pull
6
The new pull is 600 times the old pull.
The new pull is 1/36 times the old pull.
The new pull is 1/6 times the old pull.
1/9

Which statement below is known as Kepler's 1st Law of planetary motion?
All orbits are ellipses.
Equal areas between the satellite the and object begin orbited are swept out in equal time intervals.
T2/r3=Kepler's constant for an object being orbited.
T3/r2=Kepler's constant for an object being orbited.
Equal sector lengths along the obits circumference are traced out in equal time intervals.

Which is statement is Kepler's 2nd Law of planetary motion?
All orbits are ellipses. (Because there is no second law.)
Equal areas between the satellite the and object begin orbited are swept out in equal time intervals.
T2/r3=Kepler's constant for an object being orbited.
T3/r2=Kepler's constant for an object being orbited.
Equal sector lengths along the obits circumference are traced out in equal time intervals.

Two astreroids are floating in space. Asteroid "Geckotorus," mass 56 000 000 kg, is 4 000 m from asteroid "Blip-o-potimus," mass 3 000 000. The force of attraction on "Blip-o-potomus" is greater than the attractive force on "Geckotorus."
True.
False.
