The distance traveled while accelerating from rest is
D = 1/2 a t² .
For this problem, we shall totally ignore air resistance.
We do so completely without any reservation or guilt,
because we know that there is no air on the moon.
D = (1/2) · (1.6 m/s²) · (9 sec)²
= (0.8 m/s²) · (81 s²)
= (0.8 · 81) m
= 64.8 meters .
(That's about 213 feet ! The astronaut must have dropped the feather
from his spacecraft while he was aloft ... either just before touchdown
or just after liftoff.)
<h3><u>Answer</u>;</h3>
D. Suspension
<h3><u>Explanation;</u></h3>
- <u>Suspension</u> is a type of construction where the main load-bearing elements are hung from suspension cables that are then suspended from vertical supports anchored into the ground or a riverbed.
- <em><u>Suspension structures are building structures in which the main elements that support the load such as wires, cables, chains, grids, sheet diaphragms,etc are subject only to forces of extension.</u></em>
- Suspension structures may be either plane or spatial. Spatial suspension structures are generally used for large-span roofs of public and industrial buildings.
Answer:
Some planets and moons are geologically active as, earth is the planet which are significantly highest active planet ion the solar system. The geological activation are depends or vary from planet to another planet and one moon to another moon. Moon is the huge area which covered and the planets and moon are the highest temperate then, it is geologically active.
