Answer:
Let's start by understanding what exactly a scientific question is. A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A good scientific question has certain characteristics. It should have some answers (real answers), should be testable.
Here's examples of a few:
Why is that a star?
or
What is that star made of?
Hope this can lead you to the answer you're looking for at least!!
The feel of weight comes due to the normal reaction force given by the support. Hence, the condition of weightlessness is when the normal reaction force becomes zero. So, during free fall there is no support which can provide the normal reaction. Hence, the bungee jumper feels weightless as she falls towards the earth because of the lack of support force that balances gravity.
Hence, the answer is 3.
The type of energy that an unlit match has is potential energy.
Answer:
A theory is a system of ideas intended to explain something, and a hypothesis is an educated guess.

Answer:


Explanation:
<u>Spring Potential Energy
</u>
For any expression of the restoring force F as a function of the displacement from the equilibrium point x, the change of potential energy is equivalent to the work done to move the object from one point to another.
(a) The potential energy is

We have that

Thus



(b) Knowing that x=26.5 cm = 0.265 m
