Answer : The order of potential energy from least to greatest is,
(3) < (1) < (4) < (2)
Explanation :
Formula used :
where,
P.E = potential energy
m = mass of an object
g = gravity constant = 
h = height
Now we have to calculate the potential energy of following options.
(1) Tiles a 15-kilogram stone found at a height of 3 meters.
(2) 10 kilograms of water stored at a height of 9 meters.
(3) 1-kilogram ball located 20 meters.
(4) In the area box of books weighing 25 kilograms placed on a shelf 2 meters high.
From this we conclude that, the order of potential energy from least to greatest is,
(3) < (1) < (4) < (2)
Answer:
<h3>D)Moon and sun</h3>
Explanation:
Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs.

There are 6 electrons in an atom of carbon 13. Hope this helps!
I dont understand , what u write
Answer
The most abundant carbon isotope is carbon-12
Explanation:
The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.
In fact, the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.
