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.
Most likely the variables involved.
<span>It would be hotter near the Earth's equator and colder near Earth's poles</span>
<span>For maximum visibility, backing a vehicle requires a driver to:
Adjust the mirrors so that the driver can see the intended trailer path.
</span>when driver is moving backward or backing a vehicle, adjusting of mirror is important factor because a driver can see backward from the mirror.
Always park back in a space.
<span>There are also other factors a driver should keep in mind:
Turn your head also while backing
back slowly and should ready to stop any moment
if someone is walking behind the vehicle, horn the vehicle etc

Answer:
The magnitude of the resultant is approximately 5.391 units.
Explanation:
We notice that vectors have the following characteristics: A magnitude and direction. That is:
Where:
- Magnitude, dimensionless.
- Direction, measured in radians.
This expression can be rearranged as:
Where:
If we know a set of vectors of the form , the resultant vector () is the vectorial sum of every vector in the set:
If we know that , , and , the resultant vector is:
And lastly, we obtain the magnitude of the resultant by Pythagoras' Theorem:
The magnitude of the resultant is approximately 5.391 units.
