Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving.
any entity lifted against the strength of gravity stores elastic potential of gravity.

Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed
. So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
A = -9.8
v = -9.8t -8
s = -4.9 t2 -8t +25
So… -5t^2 -8t + 25 =0, we’ll rearrange to 5t^2 + 8t - 25. We get two roots, one is positive and is 1.59 seconds
V = -9.8(1.59) - 8 = -23.6
So… it takes 1.59 seconds to hit the ground at -23.6 m/s.
Answer:
hydrogen
Explanation:
pH is a measure of the ion concentration of hydrogen in a solution.
In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.
Mathematically, the pH of a solution is given by ![pH = -log 10[H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%2010%5BH%5E%7B%2B%7D%5D)
Hence, a solution with a pH of 7 is neutral.
Also, a solution with a pH below 7 is acidic but basic if it's pH is above 7.
I think the answer is potential
The independent variable is how much weight you add to the boat.
The dependent variable is: Did it or did it not sink yet ?
