What is the technique of obtaining a large number of plantlets by tissue culture called?

$A$ tube of length $L$ is filled completely with an incompressible liquid of mass $M$ and closed at both ends. The tube is then rotated in a horizontal plane about one of its ends with a uniform angular velocity $\omega$. The force exerted by the liquid at the other end is

The angles of a triangle are in the ratio $3: 5: 10$. Then the ratio of the smallest side to the greatest side is:

Which process is used to obtain products like cheese and yogurt?

The following series $L-C-R$ circuit,when driven by an emf source of angular frequency $70 \text{ krad/s}$,the circuit effectively behaves like:

Assertion : Galvanised iron does not rust.
Reason : Zinc has a more negative electrode potential than iron.
