I think the correct answer would be the child quietly sits until the timer goes off. It is ineffective because the child would be used to this process and would come to a time where he will not get something from it.Also, it would make a child feel isolated and alone which would affect hi self-esteem in a long run.

Answer:
S = 11488.42 m
Explanation:
Given,
The speed of the jet, v = 0.74 Mach
= 253.82 m/s
The altitude of the jet, h = 10000 m
Since the jet is travelling horizontally, the vertical component of velocity Vy = 0
The equation for a projectile projected from a height h is given by,
S = Vx [Vy + √(Vy² +2gh)] / g
Since Vy = 0
S = Vx √(Vy² +2gh) / g
= 253.82 x √(2 x 9.8 x 10000) / 9.8
= 11488.42 m
Hence, the humanitarian aid package should be delivered ahead of distance, S = 11488.42 m
Earths surface gravity: 9.7
Venus surface gravity: 8.8
Mercury's surface gravity: 3.7
Your answer would be D: Earth, Venus, Mercury
Hope this helps! (:
