Answer:

Explanation:
The pressure at the bottom of the tank is:


The force exerted on the circular bottom is:
![F=(73581.921\,Pa)\cdot (\frac{\pi}{4} )\cdot [(12\,ft)\cdot (\frac{0.305\,m}{1\,ft} )]^{2}](https://tex.z-dn.net/?f=F%3D%2873581.921%5C%2CPa%29%5Ccdot%20%28%5Cfrac%7B%5Cpi%7D%7B4%7D%20%29%5Ccdot%20%5B%2812%5C%2Cft%29%5Ccdot%20%28%5Cfrac%7B0.305%5C%2Cm%7D%7B1%5C%2Cft%7D%20%29%5D%5E%7B2%7D)

Keck telescope are more used in light, are visible, and is used in Hawaii.
For a regular radio telescope, it tracks and observes a much BIGGER waves, viewing in more detailed/more depth. Notice that light and it’s visibility isn’t much of a strong guidance!
Hope this helps!!
In balancing nuclear decay types of reaction, the same as balancing a chemical reaction, we use the number and the type of nucleons present for the decay reaction. Regardless of the type of decay, it should be that the total number of nucleons in the shole process should be conserved. For carbon-11, the decay equation would be as follows:
11/6 C --->11/5 B + 0/1β
It is an example of a positron emmision or a positive beta decay. It is a decay for neutron-poor nuclei where a proton is being transformed into a neutron and also emitting a positron that is high in energy.
The main difference between a covalent compound and an ionic compound is the type of elements used. In a covalent compound, a nonmetal bonds with another nonmetal (e.g. H20, NH3, CH4).
In an ionic compound, a metal bonds with a nonmetal (e.g.NaCl, KCl, MgCl2). What makes an ionic compound binary is the amount of atoms used. This includes any ionic compounds that has two atoms such as NaCl and KCl.
Note that although MgCl2 has two elements, it does not have the same amount of atoms. Mg is one atom and Cl has a subscript of 2 which makes chlorine have two atoms.

Answer: No.
Explanation: A negative integer can only be made with 2 negative integers or 1 positive and 1 negative integer.
