Please help and, please don't take this is me being ride but, ONLY ANSWER IF YOU PLAN ON ANSWER THE 2 QUESTIONS please and thank you
have a great day/night or evening sr or ma'am

1) a and c

2)b and c

Explanation:

1) the first and last box because gravitational pulls depend on the distance and size of and object to another object. If the objects are farther from eachother, than the gravitational pull decreases. Also if an object has a bigger size its gravitational pull increases.

2) b and c because it even says the spend probes are used to collect info, and it is less to use them instead of humans. Also we dont know for sure if the trip will kill us humans and we also dont know if the distance is to far to survive because that has never been proven.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
