The effort applied = 200 N
<h3>Further explanation</h3>
Equilibrium :

Total length = 1.75
The distance between the fulcrum and the load is 0.5 m ⇒ d₁=0.5 m
The distance between the fulcrum and the force applied :

A load of 500N ⇒ F₁=500 N
The force applied :

Answer:
The total displacement from the starting point is 1.5 m.
Explanation:
You need to sum and substract, depending on the movement (to the right, sum; to the left, substract).
First, it moves 4.3 m right and return 1.1 m. So the new distance from the starting point is 3.2 m.
Second, it moves 6.3 m right, so the new distance is 9.5 m.
Finally it moves 8 m to the left, so 9.5 m - 8 m= 1.5 m.
Summarizing, at the end the squirrel is 1.5 m from its starting point.
Answer:
A. matter was compressed into a single point and then exploded outward to form the universe
Explanation:
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
