The length of a simple pendulum is increased by $2\%$. Its time period will

What is the length of a simple pendulum,which ticks seconds (in $m$)?

$A$ cylindrical cork of uniform density floats in a liquid of density $\rho_1$. If the cork is depressed slightly and released, it oscillates harmonically with time period $T$. If the same cork floats in another liquid of density $\rho_2$, then the similar oscillation has time period $2T$. The value of $\rho_2/\rho_1$ is :

In a simple pendulum,the period of oscillation $T$ is related to the length of the pendulum $l$ as

The length of a simple pendulum is increased by $44\%$. The percentage increase in its time period will be ..... $\%$

$A$ simple pendulum of length $L$ has mass $m$ and it oscillates freely with amplitude $A$. At the extreme position,its potential energy is ($g =$ acceleration due to gravity).
