A probe landed on Mars and did soil tests. What information did it discover? A. The gravity on Mars is much less than on Earth. B. There are no living organisms in Martian soil. C. Mars is about one-fourth the size of Earth. D. Mars is slightly oval in shape.

We can infer that star y is closer but other factors must be considered including the heat of the star, the mass, and the brightness of the star. even though star x seems dimmer it may just be less bright or contain less heat.

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
