The answer is A.) Gravity
Answer:
To install a television antenna, a 10-meter-high pole was used and 30m of wire were used, which were attached to an eye bolt installed on the ground. Determine the distance between the eyelet and the base of the post
The acceleration is the change of speed/velocity over time. Thus to calculate this you do (V1-V2)/T or (11.2-9.6)/4 or 0.4 m/s^2
Even though the mass of the earth stays the same, the force gravity has on us will double because there is less space in the atmosphere for the gravity to pull anything in towards its center. Let me know if I'm correct!
