Answer:

Explanation:
It is assumed that pole vaulter began running at a height of zero. The physical model is formed after the Principle of Energy Conservation:


The previous expression is simplified and required height is found:

![h_{B} = \frac{1}{2 \cdot (9.807\, \frac{m}{s^{2}} )} \cdot [(10\, \frac{m}{s} )^{2}-(1.3\, \frac{m}{s} )^{2}]](https://tex.z-dn.net/?f=h_%7BB%7D%20%3D%20%5Cfrac%7B1%7D%7B2%20%5Ccdot%20%289.807%5C%2C%20%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%29%7D%20%5Ccdot%20%5B%2810%5C%2C%20%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D-%281.3%5C%2C%20%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D%5D)

Alright, so solving for the net force is a rather simple and easy step. I want to briefly explain how you determine the net force, but before I do, let's examine the problem together. What has been provided to us? What direction is it going? Well, we can look at the information!
Amanda's Force: 5 N
Jeremiah's Force: 10 N
They're both pushing on the books, but in different directions. Left and right. If Amanda is pushing the books to the right 5 newtons, and Jeremiah is pushing the books to the left with 10 newtons, that means the net force is 5. The book is being pushed to the left! We can say that because Jeremiah's force is much larger than his sisters.
We can determine the net force from the following;
Net Force → 10 N - 5 N = 5 N
In conclusion, your answer should be a total of five (5) newtons
Because many objects in space don't radiate any optical (visible) radiation at all.
And other objects, like stars, radiate a lot of invisible radiation in addition to the
visible light from them. So the ability to detect and measure invisible radiation
makes it possible to learn a lot more about objects in space than we could if
we could only use their visible light.
When the vibration is in a direction parallel to wave's motion that is a Longitudinal wave (C).
But When the vibration is in a direction perpendicular to wave's motion then it is Transverse wave.
I think the answer your looking for is chemical reactions
