Answer: 1.2%
Explanation:
Given
If one borrows $12,250
and give $147 interest on it
Then the interest is given from the formula
![\Rightarrow S.I=\dfrac{P\times R\times T}{100}\\\\\Rightarrow 147=\dfrac{12,250\times R\times 1}{100}\\\\\Rightarrow R=\dfrac{147}{122.50}\\\\\Rightarrow R=1.2\%](https://tex.z-dn.net/?f=%5CRightarrow%20S.I%3D%5Cdfrac%7BP%5Ctimes%20R%5Ctimes%20T%7D%7B100%7D%5C%5C%5C%5C%5CRightarrow%20147%3D%5Cdfrac%7B12%2C250%5Ctimes%20R%5Ctimes%201%7D%7B100%7D%5C%5C%5C%5C%5CRightarrow%20R%3D%5Cdfrac%7B147%7D%7B122.50%7D%5C%5C%5C%5C%5CRightarrow%20R%3D1.2%5C%25)
Thus, the annual rate of interest is 1.2%
122.65 or 122 kilometers per hour
8 km is not a speed. And even if it were, we would still need to know how much time Charlie spent running.
The best answer is C.
The stability of atoms depends on whether or not their outermost shell is filled with electrons. If the outer shell is filled with electrons, the atom is stable and therefore they do not need to react with other elements to become stable.
On the other hand, atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability. To achieve stability, atoms will form two types of chemical bonds called ionic bonds and covalent bonds.
speed of sound wave depends on elasticity of medium and density of medium
it is given by formula
![v = \sqrt{\frac{E}{/rho}}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%5Cfrac%7BE%7D%7B%2Frho%7D%7D)
now if wave travel through solid then its speed is maximum while if it travel from gas then its speed is minimum
so initially its speed is given as 4000 m/s and suddenly decrease to 1500 m/s
so here we can say that its medium will change from solid to liquid
<em>so sound will encounter with water </em>
