I got some of these questions like this
(1) If you could buy a pound of chocolate on the Moon, using a pound scale from Earth, you'd get a lot more chcolate than if you bought a pound on Earth.
(2) When an astronaut goes on a space walk outside the Space Station, she will quickly float away from the station unless she has a tether holding her to the station or constantly fires thrusters on her space suit.
(3) I used Newton's version of Kepler's third law to calculate Saturn's mass from orbital characteristics of its moon Titan.
(4) If the Sun were magically replaced with a giant rock that had precisely the same mass, Earth's orbit would not change.
Do you think each of them are true or false? scientific explanations would help alot!!
