Which valve is located between the right atrium and the right ventricle?

$A$ cybrid is a hybrid carrying

$2 \tanh^{-1} \frac{1}{2}$ is equal to

$A$ meter bridge is set up as shown to determine end corrections at $A$ and $B$. When a resistance of $15 \ \Omega$ is used in the left gap and $20 \ \Omega$ in the right gap,the null point is obtained at a distance of $42 \ cm$ from $A$. When these resistances are interchanged,the null point is obtained at a distance of $57 \ cm$ from $A$. The values of the end corrections are:
