The most widely accepted theory about the universe is the big bang theory.
<h3>What is big bounce theory?</h3>
The Big Bounce theory refers to the universe that is expanding and contracting, move back and forth in a big-picture timeline. The Big Bang theory was happened about 13.8 billion years ago when the universe began as a tiny, dense, ball that exploded. Many astronomers use the Big Bang theory to show how the universe began. But what caused this explosion in the first thing that is still a mystery. It has passed through many stages, which can be considered cosmological theories. The flat Earth, the geocentric model, heliocentricity, galactic centricity, the Big Bang, and the Inflationary Big Bang. In the Big Bounce theory, the universe is expanding and contracting, seesawing back and forth in a massively big-picture timeline more specific theory called "Big Bounce" theory proposes that the universe could collapse to the state where it is first started and then initiate another Big Bang.
So we can conclude that The Big Bang theory says that the universe came into being from a single more than 13 billion years ago.

B. Brittle Star is an echinoderm that moves by waving its arms.
Brittle star is a spiny, hard-skinned, long-armed animal, related to sea star, that lives on rocky sea floor, from shallow areas to the deepest areas. It uses its flexible arms for locomotion.
Answer:
To find the value of the unknown weight, we previously placed the 3 known weights and made a graph of the force against displacement
When hanging the weight is known, we measure the displacement and from the graph we can find the value of the hanging masses
We can also use the equation and multiply the constant K by the displacement and this is the applied weight.
Explanation:
For this problem we will use the translational equilibrium relation
F –W = 0
F = W
W = mg
The spring elastic force is
F = - k x
We substitute
k x = m g
Where we see that the force of the spring is equal to the weight of the body.
