Concave.
A surface shaped in such a way that the center curves inward like this:
Convex.

I just took the test I hope this helps. :)
The total gravitational force on the astronaut is greater in the second case. But the additional force is the attraction toward the planet. The force of attraction toward the moon is the same in both cases.
That's another interesting thing about gravity ... Nothing blocks it or shields against it. The strength of the gravitational force isn't affected by whatever may be between the two bodies.
Answer:
A) 9.8m/s this answer is correct.
The acceleration is increasing by 0.9m/s^2 .
so, in each second it will increase by 0.9m/s^2.
Therefore, in 2 second
0.9 * 2
= 1.8m/s
Now,
8 + 1.8
= 9.8m/s
Answer:
Distance travelled is 7 meters and the displacement is 3 meters
