Answer 1

Step-by-step explanation:

Given

$principal \: (p) = rs \: \: 16000 \: \\ \\ rate(r) = 20\% \:per \: \: annum \\ \\ = \frac{20}{4} \% = 5\% \: \: quartly \\ \\ time(n) = 1 \: year \\ = 1 \times 4 = 4 \: \: quartly$

Now

$Amount\: = p(1 + \frac{r\%}{100} ) {}^{4} \\ \\ = 16000(1 + \frac{5}{100} ) {}^{4} \\ \\ = 16000( 1 + \frac{1}{20} ) {}^{4} \\ \\ = 16000 \times ( \frac{21}{20} ) {}^{4} \\ \\ = 16000 \times \frac{21}{20} \times \frac{21}{20} \times \frac{21}{20} \times \frac{21}{20} \\ \\ = \frac{21 \times 21 \times 21 \times 21}{10} \\ \\A = \frac{194481}{10} = 19448.1</p><p>now \\</p><p>Interest = Amount - principal</p><p> \\ = 19448.1 - 16000</p><p> \\ =3448.1$

Answer 2

Answer:

Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.
