Answer:
Explanation:
Let the forward displacement is taken is positive, and the backward displacement is taken is negative.
first displacement = + 18 cm
second displacement = - 6 cm
third displacement = - 12 cm
net displacement = 18 - 12 - 6 = 0 cm
1. The successful launch of communication satellites
2.More people will be interested in studying science
But science would probably be focused on space exploration and there will probably be less scientists in other fields such as chemistry.
