Comparing eq (1) and (2), we have: i. $2 \pi f t=100 \pi t \Rightarrow f=50 \mathrm{~Hz}$ ii. $I_o=20 \mathrm{~A}$ iii. $I_{R M S}=\frac{I_o}{\sqrt{2}}=\frac{20}{\sqrt{2}}=14 \mathrm{~A}$

Why Happiness is Considered the State of Mind

Happiness and satisfaction are the state of mind. It can never be assumed that a person is happy due to too much money or having plenty of facilities. We can never say that a person is happy after being well settled. Rather we generally see poor people more satisfied than the rich.

The crow tried its level best but all in vain. At last, the crow used its intelligence and got a solution to raise the water level for its easy access to drink. The crow saw some pebbles near that pitcher and started picking these pebble
